run o&o shutup, you can disable alot more of that windows 10 rubbisch telemetry
Would resetting the PC from the recovery/startup options work? That options leaves the OS but deletes all user data.
EEVblog or you’re raiding the “eviction” dumpster in your business park.
@@Damicske Nope, you cant, suricata still picks it up even if you disable everything.
@EEVblog Install that junk without internet and it will allow local account.
I wish I had one of those Magic dumpsters
No kidding, can't even find deals on stuff this modern on local classifieds most of the time where I am let alone for free.
If I had access to that dumpster room ....
Well, let's just say finding a home for things would be my challenge - and one of those things would be me.
If I had access to that dumpster room I'd have a side hustle in used PCs and test gear on ebay -- no foolin'.
You'd be able to make a living on all that stuff
I would install a camera to get latest updates for that dumpster.
You are trying to say you are homeless in the most confusing way or what..?
@@a51mj12 I am not homeless - but that might change if I bring more stuff home than I have already :-D

left a comment but, check out PCunlocker . bootable tool you can put on usb and get access to change any user password and make them local and stuff. Great for dumpster diving.
The power connector has three connections: Vcc, Ground and Sense. Sense is the middle connector, ground is in the two contacts you already identified. The Vcc contacts are facing the ground contacts on the middle plastic part. They are a bit hidden.
These Lenovo chargers are not smart. They have a specific resistance connected between the sense and ground so the device knows how much power it can draw or if it wants to run at all.
@@EEVblog Yeah, that's what I said. Ground are the two outer contacts and the Vcc contacts are attached to the middle plastic part and facing the ground contacts.
@@EEVblog The diagram you showed was technically right. The VCC is pointing to the contacts on the inside of the connector and the ground is the outside of the connector. superuser.com/questions/1246823/lenovo-trim-yellow-rectangular-power-adapter :)
@@EEVblog You were looking at a Lenovo Laptop some years ago i think? or some other Lenovo product, it used their old style of power plug but it's the same deal, and it also caused a headache for you there.
I had another look, and yeah, it's almost impossible to see those inside contacts. That makes bodging something really hard.
EEVblog That looks a lot like the lenovo thinkpad laptop charger connector. Edit: I see you already found that out
I think I'll try and use this as a large screen capture drawing tablet. My Microsoft surface is messy for this, but this has the perfect 1920x1080 screen capture area, the touch screen, and support for a 2nd monitor to use for recording monitoring.
That's a cool idea. I'm picturing it attached to something much like one of those adjustable drawing table that swings from vertical to horizontal.
For software to improve the touch usability I know Epson has a drawing suite meant for their line of IR projectors for smartboard functionality. I don't recall it being locked down given it was meant to be compatible with all the proprietary software from earlier smartboard mfgs. Thinking about it I might have to try it myself on one of those 2 in 1 laptop/tablets.
The best way to clear up space and clean Windows would be to get a USB with Windows 10 and blow away the old stuff, there will be a partition with a OEM recovery image that will take up a fair bit of space on the drive that is not needed as well. Win 10 OEM activation is all in the BIOS so no keys to worry about either.
@@michaeljames1893 I just killed the Norton Backup files and some other stuff and it has 177GB free now. Plenty.
Its probably got another ram slot on the back side of the motherboard. if you actually plan on using it, integrated graphics benefits greatly from having dual channel memory. if you have another 8gb sodimm ram stick laying around it would be worth it to throw in there.
Dave -- I know I'm being paranoid, but: computer found in the dumpster room? Might be worth a fresh install out of concern for malware/etc on the machine? Even if not done maliciously, the previous owner may have been lax about things (and Norton obviously isn't much use.) I'd personally be pretty hesitant to put any serious data on there. At least use a different password?
well - that was a classic horror movie opener - "I've found this aio computer in the dumpster and there's nothing wrong with it!"
The shop I used to work at back in college ended up with some early aio machines and what a nightmare it was for me and the owner as the machines were such junk.
4:27 ... If you look closely, the icon above the power jack shows "-" on the outer ring, "+" on the inner ring and then there's the dot in the middle for the centre sense pin.
I came here to point that out too. The icon is a correct representation! 😀
Came for the title, stayed for the enthusiasm! Your positivity is contagious, Dave! That little walk-through on removing the OS password was an unexpected bonus :) Keep-em comin', mate!
Allow me to jump in and defend this AC jack for a moment.
These rectangular jacks were originally found on the T*4*-series of Lenovo laptops as a replacement to the barrel jack.
They have a greater shear resistance comparatively to the barrel jacks of yore due to the increased soldered area to the circuit board and the reduced height, making them much sturdier and harder to rip off than a barrel jack.
These days, we have USB C, and it's all nice and standard :)
I have a ThinkPad that has one of those and the weird thing is that it also had a barrel Jack
I hadn't considered the increased soldered area but I feel like they could just as easily have made a stronger barrel connector. Like they barely save maybe 2.5mm on this construction just to make a ton of accessories useless, for a port that is electrically identical to the old one.
i dont have usb c charging on my p1 because its too damn powerful. It will charge with PD but it wont be able to reach full power without a slim tip.
@@Nukle0n they made a better barrel connector before that and it was big and ugly. the slim tip truly is the best power connector when it comes to high power draw. anything below 100w luckily gets usb C now.
I have an L390 Yoga with USB C :) loving it, Powerdelivery lets me charge via my truck's 12v and phone's power bank. Saw this on my buddy's cheapo laptop with that and honestly not too bad, better than the barrel on my old dell
Windows exploitation with Dave, now on SECVblog
A windows 10 reinstall would have been better, the key is built in. UEIF or whatever that acronym is. When installing windows, it attempts to trick you to get a Microsoft account, but you have to keep telling it to piss off. I will be done with Windows if they ever force that.
I was impressed, but I would've just fetched and dumped the drivers onto my Windows 10 installer flash drive and done a clean install...
@@RickyX64 What "drivers", there is nothing to it. Its not like the days of old. That's why windows physical memory size is so massive, from the libraries. Either way, any real nerd would have a SSD with Linux ready to go. Also, I went to try Arch linux, turns out, its not so straight forward lol. No wonder people flex with it. I shall too.
@@Wtfinc Most newer (non-OEM) motherboards do require their network adapter drivers to be installed first :)
@@rkan2 OEM Shmo-EE-Em lol, no big deal. easy 3min job to find all, what, two drivers u would need. like u said, network, an likley touch.

I almost can't believe they still havent fixed it though... That's about a 20yo exploit...
@@ThePlacehole Ah, so it's from the good old days, where one could pwn windows with big enough ping packet, certain vector image and just by browsing folders with links in them in general :)
Classic Windows✨
@@ThePlacehole Its not a bug but a feature
@@ThePlacehole they dont have to fix it, if you have access to the physical stuff you can do more than just removing the password or adding a user :3
I got one of these machines with an i7 from the dumpster about 6 months ago! Use it every day. It’s very nice.
Today I learned that windows password security is even worse than I thought it was.
BigJoe_Buster The only thing that’s secure from the manufacturer is Apple’s encryption at the boot level. MS just fails hard. Even their hardware bitlocker encryption is trivial to circumvent.
This type of security is always difficult though since you have physical access. On Macs, if you have physical access to get past boot you can reset the password from the restore mode without any screwing around.
@@Alexlfm Yep, all Macs have FileVault enabled by default (quite nice too, the T2 chip handles all encryption). And starting with Catalina, Macs have the same activation lock as iPhones (so if your laptop is stolen, it's basically a brick to them since it'll need the iCloud account details to reset).
Physical access defeats all security short of an encrypted drive. But with a more secure OS on the drive you'd have to boot a different OS to bypass the security.
@@hanelyp1 That will stall them for at least 2 minutes
@@Alexlfm How is Bitlocker trivial to circumvent?
Welcome back Dave, good to see you back on it. Looking forward to the fence controller diagnosis and fix, interested to see what kind of voltage and (milli?)amperage it kicks out.
I love that you showed off this hack. It's one of my favorites. It's funny that since the XP days, they not only didn't fix this simple hack but made it easier where you don't even need to boot from a disk or thumb drive.
"NSA Spy enabled" got me 😂🤣
You did it backwards... You forgot to tear it apart before turning it on 😁
Awesome! Have a good year, Sir.
"I'm sorry Dave, I'm afraid I can't do that."
Its actually quite a nice connector, survived many years of abuse on all my thinkpads.
Wait, wait, wait... Avast AND Norton?! BAHAHAHA No wonder you found this thrown out!
Haha agreed.... 😁
Most issues I run into in Australia with computer problems when I fixed computers was them running slow. I always discovered it was one of three issues; Windows was corrupt (and windows 10 corrupts easily), conflicting security software or bloatware, usually in the form of free software attached to downloads. Also, there is that other issue with the 2018 build of Windows 10, you literally have to reinstall windows if you want to version update past it, because it has a bugged updater.
Windows huuuh
Jerry Dodge yeah,like a finding two turds in a diamond.
@@foxdavion6865 Or the 4th one - the users browsing habits arent terribly good, and you end up removing 15 toolbars from I.E. (because they're not smart enough to use a real browser) and then wait as MBAM or similar antimalware software removes the 13,000 PUP's from the machine. Boom instant speed demon again :)
The Lenovo plug has 3 connectors, the center pin, the inside of the "shroud" and the outside. The center data for the computer to communicate with the power supply, find out what model it is, etc, althought it's not a DRM thing where it doesn't work if it doesn't detect something, but this is how it was even on their old connector, they just changed the shape of it, and I believe you struggled with this on another occasion with a Lenovo laptop.
Reminds me of when I scored a HP Color Jet CP1515n printer with half-full toner cartridges during a roadside council-cleanup. The printed image in colour was not entirely spot even after re-alignment procedures. Somehow, two years after hefting it home, the alignment came good, so it really became wiinner-winner-chicken dinner fodder.
I really like how you patched that modular synth system
I really had a struggle when I came across those big yellow barrel connectors on the far left at 5:04. They also have a center pin, but it was not connected in my case. There are two seperate tubes in the outer "ring" and the inner one was positive...
Most laptops connectors with centre pin are like that.
I bought my missus one of those machines early last year. It's been a great machine. I'm sure Mrs EEVBlog would enjoy it.
Great find! And thanks for the windows recovery tutorial.
Thanks dave for peeling the protective covers off. I was starting to sweat and shake while I watched.
If you are reselling, it is MUCH better to leave them on. Same as factory screen protectors on multimeters, etc. It's there to protect the screen, so let it do it's job.
You'll love those square connectors Dave, especially if you have any other Lenovo gear. They were standard for several generations of Lenovo hardware, before being replaced by USB-C. You can get the power adapters for peanuts from a place like eBay, or hell, you might be able to beg some if you have any local enterprises that use Lenovo gear - they'll have totes overflowing with them!
edit as I watch the video: Yeah, they're bidirectional and can be inserted either way.
Great find! Wow, so jelly!
Note for non-Australian viewers: "Gone Walkabout" is an Aussie expression for going away for a holiday/vacation. It has its origins with the habit of some Australian natives of working for a while then wandering their traditional lands for a while before perhaps coming back to work some more.
Damn, it's April already??? How time flies eh? :P
Thanks for the password reset cmd tip. That's exactly what I needed today for a laptop and it work the first time, unlike yours witch had a Microsoft account :)
Jiminy Christmas! I have to imagine your whole neighborhood must be outfitted by this time with free PCs from the magical dumpsters of technical generosity.
Glad you are back. I was worried the fire got you mate
The Positive doesn't actually point at the center, it points at a circle around the center, between the center and the outer circle.
"I don't have the proper power supply for this, lets jam wires in it's butt" :D
Nice find! All-in-one would be nice to have next to my head banging/healing bench :) Will check the usual getting spot soon, but it's usually just crap in there.
That guys is addictive, really like his videos and enthusiasm.
Man, I wish I could find the dumpsters you dive in... Geeez
On how I screamed… Apparently on some cheaper Lenovo laptops the center (ID) pin is connected directly to superIO and putting 20V across it kills it.
No zeners, sidacs or suppressors???
@@watchmakerful Nothing, just straight trace to SMC, I blown one myself. Fortunately new preprogrammed chip was just $15 or $20 delivered.
That is what happen to me I guess, did the same like Dave with a lenovo laptop (with same connector) and a smoky smell arose. Be careful kids. ;-)
Incredible. For next Christmas I want a dumpster like Dave's.
That's a really awesome dumpster find! :) Nice one! :)
Greetings from the Netherlands :)
Excellent find, congratulations! I still use 10 year-old processors with excellent performance, let alone something so new like this. It is quite hard to understand how this would end up in a dumpster - hopefully it is a simple case of novelty that wore off. That or venture capital that flooded towards one of the startups/companies of your building.
If it wasn't for Windows 10... :D
What's wrong with Windows 10?
Esse Vbe tá em todos os lugares, KKK
Nothing, if you don't have a computer.
Windows 10 is fine, but please keep on using unsafe 11 years old Windows 7. There's other OS if you don't wanna be part of Microsoft's rat race.
@@Nukle0n more safety is Debian than bloody Windows.
Yesterday I felt lucky when I found a Casio fx-82 in a dumpster....
Such an amazing find!
@Dave instead of 'hard shut down', at the login screen, you could connect a keyboard and mouse; click on the power icon, hold down shift on the keyboard and click restart.
Seems like it'd been easier to just reinstall windows and get a nice clean install with none of the old user's crap.
That is what I'd do once I saw it was at least attempting to boot- wipe everything and reinstall
Yeah, though I would have been installing Linux instead. Still not quite sure how I should be organising things with multiple drives, though.
there's huge risk you are forgetting; the touchscreen drivers. They aren't standard yet so Windows didn't have them in repository. If you just reinstall Windows without checking first then I'm afraid you won't find out the screen is a touchscreen at all.
@@xponen It would seem likely that the touchscreen driver was available to download... maybe from some fancy web of sites that covered the whole wide world.
@@jmonsted you are right, it is probably on Distributor's website, but the scary thing is that the OEM might not upload their driver & configurations online instead pass it on to Distributor to upload it online. In a good example we have Intel who provides driver on their website while the Distributor customise the driver and re-upload it on their website, but for other OEM they do not provide a website for download and the Distributor might not either or just didn't update them.
The video title should be "How to hack into a Windows 10 computer"
Nice Vlog Dave
That's a cool workaround to get command prompt/superuser access
Wow you just found great PC with 23" monitor. Great.
I usually use the regedit trick instead, you plug a Win10 recovery USB stick into your PC (really just the standard Win10 installer), boot up to it, press 'shift+f10' after going a couple of steps in, type 'regedit', load the c:\windows\system32\etc\system.dat hive into the registry, and change some stuff, basically this: winaero.com/blog/reset-windows-10-password-without-using-third-party-tools/
Really handy thing to do, either way works though.
Ray Herring reminds me of the day when Win2K could be bypassed by an original boot CD, which was patched. How life has come full circle, eh?
Nice score there Dave... Well done!!! 10/10
You can also get into system recoveryby holding down shift whilst clicking on reboot in the power menu on the logon screen
What a scavenger! I love it. :-)
10:48 even with Windows 10 Home 1909, just click "I don't have internet" and it'll let you make an offline account ;)
He should have fresh installed... More effort bypassing the password.
@@PaftDunk no, he doesn't have the factory default driver for the touchscreen and the pop-up camera, it would render them useless or function inappropriately.
@@PaftDunk For sure, plus you don't want all the previous persons garbage software on there and who knows what viruses/malware is hiding on it. Boot off Windows 10 USB, diskpart, "clean", install. Done. Clean.
@@xponen That's not too hard to fix: either the drivers will be fetched through windows update, or a simple search for the model number will bring you to a page where you can download them.
@@VisibleReality Window updates did not and will not include the driver's OEM tools used to configure the driver, eg: for calibrating Windows tablet's sensor, such as orientation (up down left right). Also a Touchscreen driver have same name but different resolution depending on model being used on; eg: the difference in resolution, the place to put OEM button for tablet. In camera devices there's also variation; like an Imaging system is host to a modular camera with its own driver, better install the right one in sequence.
There are extra connectors on the inside yellow square which are the positive. The centre hole is indeed the power detection.
Wow. That is quite the find. Respect.
I cannot believe someone would throw that out, it's really nice! Damn throwaway society is ruining the planet.

That "GC-0700 (Samsung)" marking is showing what plastic the mold is intended to be used with. There are several vendors making a "GC-0700" ABS/PET mix, but they have some variation in characteristics and so for the best part quality you want to run production using the same plastic the test shots were done with.
5:46 I remembered you posted on Twitter yesterday about finding a power adaptor for this, and I couldn't make out the label in the photo. I thought it took the 90W or 135W power adaptor, and was going to post about the same 45W power adaptor you found that I had for my ThinkPad X250, albeit with a UK plug rather than an Australian plug.
Daves new years resolution. Become an expert windows computer hacker :-P
LOL, that's about my limit.
yeet "published 1 minute ago"
edit: the hdmi port might be an input, have seen a lot of AIO pcs that double as an external screen for your laptop or other device
That's true. The HDMI port on many AIOs is more often an input, rather than an output. It means you can run two PCs but use the same screen for both. There might be a selection for the HDMI input in the setup - Internal/External/Auto. Some people prefer to do that rather than run a virtual machine for the second platform because it's technically a lot easier, plus it can also be handy for occasional use stuff like a media box or a R.Pi.
Only AIOs with quite a decent graphics sub-system will have an *output* capable of running a second screen - higher end Asus etc.
My college has some Dell AIOs from about mid 2018/2019 and on the back there is a HDMI connector for input and on the side next to the brightness controls is a button to switch the display input so its more likely that the HDMI input is so that the PC can be used as a secondary monitor when the PC becomes outdated. It may also be that Lenovo (or any other manufacturer of AIOs) just take a generic display panel that they would normally be using in a standalone monitor and then integrate its controller board into the PC's Motherboard and the Windows Operating system in order to lower cost which is probably why almost no AIOs have any Linux Drivers or at least to any of my knowledge.
It's both an input and output.
Nice score Dave kudos.
Nice score, Dave. Wow, what amazing security there is in Windows. You don't even need any special software to bypass the login password if you have access to the power button on a machine. :P
Keep in mind that it doesn't need to be that easy if the owner decided to make it more secure than that. The Macs are just as easy... anything that stores user credentials on the device itself can be hacked.
Don't forget to put cmd.exe back :-D
Алексей Рукин should have used the copy command instead of rename. Microsoft’s next update will check hashes of executables and block those not originally installed.
Dumpster dive pc that isn't 25 years old. Why doesn't this happen anywhere but where famous youtubers live?
o0julek0o if you know someone who works at a dump or an electronics recycling centre... people dump some insane crap. I live in the country and a nearby tip got an electrician I know to test a bunch of electronics they wanted to resell. Including an I9 a bunch of laptops and PCs from the last few years and a Gas Chromatograph which still sells for $20000 on ebay.
They also had a bunch of workshop equipment and pretty much the only thing that failed was a 3 phase welder. Everything that passed worked. As far as I know They just chucked any storage on the computers and their office computer which was running Windows XP is now a fancy I7 all in one so I suspect they found uses for everything they didn’t want to sell.
Dave, you are hilarious. I felt a stirring in my loins as you pulled off the logo protection plastic film :-) loved it
We both need to get out more...
Quite like the square Lenovo adapters, compared to our other DC adapters those types are quite sturdy.
reason for throwaway was probably Norton license expired :)
17:53 -- "And yes, I really do find this stuff in the dumpster! I have to keep saying this!"
A few years ago you made a video about a $250k Oscilloscope you'd "found in the dumpster." When I asked you whether or not it was actually some kind of "wink wink, nudge nudge" promotional video for the manufacturer, you outright called me an idiot for thinking it was _ever_ even possible that you _could_ have found something like that in the dumpster, implying everyone is just supposed to _know_ when you're showing a legitimate dumpster diving score versus a product some company offered to send you for a review that you knew would make for a good video (which, in my opinion, is a wholly valid reason to make a video -- if the content is good and you're honest about its nature, why shouldn't you make a little extra money). Naturally, after you said something to me, I got literally hundreds of comments from people calling me stupid, openly wondering how I'd survived long enough to ask you that question.
Now you're here saying, _"Yes, I really do find this stuff in the dumpster! _*_I have to keep saying this!"_*
You're a brilliant person, Dave, and you make excellent content, but you _know_ why people question the legitimacy of content like this.
Congrats on the new PC regardless.
That was April's Fools Day
Just check the date. If it's April 1st (or March 31st in the western hemisphere) then you can assume that it's bunk. Personally I hate April fools jokes but I don't resent others for having their fun.
epic find,
nice password bypass too,
thank you kindly
Nice score Dave, fancy one myself now!
Why go through all this complicated renaming of the files, when you could just reset PC to the factory condition through that same troubleshooting menu?
To see if there was any data left on the device such as a crypto currency wallet or something else

I know the reason for throwing it out: screen is little bit dusty.
The smoky forest blaze which launched a thousand PCs.
Good for you Dave!
got a universal adapter that came with the square bit, had no idea what it would fit until I saw this video. that makes sense now
fastest I've clicked on a video in a while :)
Looking at the stats after release, I actually haven't seen this many views per minute in a long time.
It's definitely broken, it's infested with some sort of malware called windows 10. Luckily, the fix is pretty easy, you just need to install Linux on it.
Shift-F10 is a good key combination to press. It opens a shell in the setup, probably in the recovery too.
PSU tips are available for laptops to convert older Lenovo DC barrel connectors to that rectangular style - or at least look very similar. They're only a dollar or so. "Thinkpad PSU plug " would be a good search term to try in Ebay - but carefully sheck the pics to make sure it's the same.
Wow! Nice way to start the year!! :)
Nice find!
I found a pretty neat noname "time>" 19" 4:3 lcd tv quite a few years ago. It has pretty much everything except hdmi and handles all the retro stuff i can think of.
Happy New Year
Great find !😎
Lol I got a universal laptop power connector kit like yours and it has the exact plug you're looking for. Thanks for the recommendation!
Great find
That connector is a special Lenovo one, like the big round one. They used the round one until 3rd gen und the square one until 8th or 9th gen. Since then they use USB-C.
one heck ofa find! awesome! 😁 that charger looks the same as one for a Lenovo laptop! wish i could find those!
I really like your work brother.
You can also access system recovery mode by holding shift while resetting the computer
Hey Dave - a general remark to these items & also to your laptop videos:
ALWAYS the heatpipes go dirty over the time and it's a nightmare to clean them. The ability to remove heat always lowers over time. The plates that distribute the heat from the pipe to the air are so close by - they can only collect dust.
So I suggest, if you already open such a case, remove the ventilator and remove the dust / mold between the ventilator and the heatpipe - for example by vacuum cleaner.
When ever I opened a used laptop - the heatpipe exhaust always was completely dirty.
Great find, I wonder if you could use that WiFi M.2 slot for an eGPU. Different keyed slot to NVME yes, but I'm sure you could find the right adaptor out there.
great little rig for a guest
