Ah a very lucky customer indeed! I had one this week from another computer repair guy who found me on Google. He changed the hinges on a HP laptop for his customer and did not unplug the battery before working on it, including unplugging and plugging the screen cable etc. I checked it over and found a short but unfortunately it was the chipset. :( Anyway, I wanted to say thank you Sorin because without you I probably would never have decided to start doing board repairs two years ago. Before that I was like most of the other repair shops; just replacing motherboards.
Former Dell tech. Yep; BIOS locked up. As surmised, could be from owner not having system fully powered off and battery + AC disconnected before changing the drive. Disconnect battery and AC and hold power button for about 20 seconds. Reconnect AC first and try to power back on. If still will not, disconnect again and hold for 20 seconds again to drain residual power. Reconnect battery. Press and hold the CTRL + ESC keys and plug in the AC power. Keep holding the keys until the KB lights up or you see other lights on the system or LCD light up, then release keys; this should bring you to an option to reset the BIOS.
@@brlin As stated, it was speculation on my part. However, changing any hardware while the system is not fully powered off can cause it to lock up. If it was in a suspend/sleep state, then by definition, that lockup would be within the BIOS, as the OS is not actively controlling the system. I have also seen this happen if the system battery fully drains while the system is in suspend/sleep mode.
@@brlin Have you ever seen bug-free BIOS? I've been writing software for living about 25 years and I can honestly say that BIOS is typically the buggiest piece of software running on any computer. I'm positively surprised every time a BIOS works correctly so I'm not surprised at all to find out that the BIOS was locked up. The biggest problem with this hardware was difficulty of resetting the BIOS. I would't trust some key combination to reset the hosed BIOS.
We never know if we can or can not fix anything until we take a look inside and that is time and knowledge consuming. If some people don't understand that, then, things are going very bad in this world...!!!! Great video.
Master Sorin for the dell laptops first thing before open the laptop always try to keep pressing power button and connect the charger while pressing, if its frozen bios the laptop will turned on 🤗👍🏼😎
Hi Sorin, a proper lucky calibrated customer😆yes strange Dell don't make simple access to BIOS battery.. mormaly yes, but finally you repair and tech us another one...thanks very much bye Francesco Timpano from Florence Italy
Hello Sorin. Few years ago I just to buy laptops from my company with description of not working. It was all dell's and every single time it was cmos battery issue, too low or just simple disconnect need to be done. Company around 1,5k workers and around 15 pcs per year was not working. I just to buy them as a parts for laptops that ware with damaged screen etc and all, all! Ware OK 😂 love jour video ❤
Very interesting. I haven´t seen a fault like this before. I´ve gotten cases of corrupted BIOS where the laptop can´t POST, but I never got a case where it takes no current. Thank you!
Good job, but I would at least clean the fans from dust before returning it. I swapped my SSD in my second hand Dell Latitude and I watched a few videos to make sure I did it right, even checked the dell's website. They even recommend you to touch another surface before putting your hands on the machine, to limit static discharge. No drama, all going well.
I help people with IT related issues once a week at my local library - It's called Ældresagen here in Denmark - I've seen this kind of error a few times before. Laptop is completely dead, required the battery to be removed in order to fix it. I suspect it has something to do with UEFI boot procedure getting stuck 'somewhere' and the BIOS battery 'remembers' the state, making the laptop appear dead. Here the customer removed the SSD, making the partition UEFI is looking for disappear - so it got stuck?
that's why when I need to change the ssd/ram, I always restart the laptop, make sure it's entering the bios/boot menu and shut it off it's still better than shut down the laptop from windows state
Diagnostic fee in hands of skilled technician makes perfect sense. Diagnostic/Bench Fee at large chain "would you like a warranty with that" shop is just a scam. There is no incentive to actual repair when boss is giving you 15 minutes to diagnose and can make $300 an hour just off of "no-fixes". I have fixed every "no-fix" from one of these facilities.
As you say - putting bios battery in a hard to access location is not helpful. My Gigabyte Brix was the same but luckily removing the motherboard is easy on that.
I had this on my current laptop. Luckily there was a post on a forum. My wife watched silently and concluded: I was sure that laptop wasn't coming back.
Exactly, why put the BIOS battery under the motherboard? Dell design choice is poor, I was working on a Dell XPS laptop. It wasn't powering on because of a dead CMOS battery..
Amigo, you denied looking at my XPS 15, for powering off randomly and other crap. The problem with it was the dead bios battery. It still has battery charging issues, however after replacing bios battery, it turns ON and works fine
You say the customer must have removed the ssd whilst the laptop was powered on or in sleep, but yet at 15:10 you didn't shut the laptop down properly or disconnect the battery before removing the ssd! so in doing so you could have caused other errors
Now you see the liability of an battery and constant power supply which obviously should have been isolated before any work was carried out, i am assuming that was the issue failing to islotate and this is why i dont favour any electrical device that runs on batteries as that item the battery has sent many an good device still with an reasonable service life left in it to the scrap heap... in fact what with non-removable batteries now fitted into mobile phones as standard means that this issue can only get worse..
Had a similar issue before. Asked the customer exactly what they did for the problem to arise in the first place. Just getting all information before tackling a job. Especially with high end laptops, gaming laptops, etc. Usual issue when the drive is replaced. Great diagnostics!
THIS VIDEO IS MISSING SOMETHING???!! I GOT IT ,IT'S MISSING THE FAMOUS SATISFYING SENTENCE WHICH IS ( *WE HAVE PICTURE* ) AM I RIGHT?! AND BY THE WAY SIR *I'M NOT BEING SARCASTIC NOR MAKING SUCH A RUDE JOKE NO! I REALLY LIKE IT WHEN YOU SAY IT MR. SORIN*
I got the same issue with my Thinkpad T14s Gen 3. No charging, no powering on. The problem was indeed a frozen bios. Internet I pressed the hidden button on the back of the laptop for 5 seconds, and after that pressed the power button, the laptop turned on just fine
that was interesting - sounds like he did not have the ssd plugged in properly and it corrupted the BIOS settings - I had an HP some years back - I was adding something that required a BIOS update, and it turned out that update itself was corrupted - I lost Video - I had a second notebook that was the same model so I striped some parts - no joy, I even bought a new BIOS for it, still no joy - the electronic stores where I used to be able to get schematics for anything no longer exist here in South Florida - I finally gave up on it and the wife bought me a refurbished same model that I put in my nicer case and keypad - so basically I had to replace the motherboard - I enjoy watching your trouble shooting from time to time when I see them - I have been subscribed for a couple years but have not seen a new Vid in some time -
Dell has a nasty advanced BIOS with lots of secure boot settings. Can be by swapping the ssd the bios detected the change. It should boot and give a warning. But maybe it got frozen instead. I change often ssd’s on brand new dell notebooks and this is always scary. After changing hardware it takes a while for the bios to get into post mode
The ec on my later models of this laptop need the chipset to work and send the ec firmware to the ec, my xps 7590/precision 5540 seems to have a dying chipset, if i let it shutdown for too long it doesnt react to power button and I have to reheat the pch before it would start
Actually, this is a common fault. Usually it happen with DELL and HP laptops. I'm not a repair shop guy but a Tech support in an hotel and i can guarantee this since we work with mostly hp and dell devices (desktop and laptops). Before diagnose what i always do is disassemble the entire PC/Laptop device and do a hard reset (Take out the CMOS battery and hold the power button for around 10 to 15 seconds to discharge completly the device) and after a couple of seconds i turn it on and everything is working fine. If it isn't then is something else. So as a recommendation, you can try this at first or as a last resource if everything you try is not working at all before doing deep diagnose.
Had a similar fault here once, I think with a Lenovo laptop. I saw somewhere that when there's no button to reset the bios, you usually hold power for 30 seconds to 1 minute.
I like dell my CHEAP & rarely have issues besides the power jack especially Precision this was surprising. Going through your channel now though it tells a different story 😂 I wish I could bring you this Toshiba portage z30t-c I got with no power…….there is no bios battery like this unfortunately 😭 not even sure it’s worth repairing
Some Acer laptop models (and Lenovos?) made in the last few years have a "pin hole" where you can insert a "pin" to reset the BIOS. I work in a school (I.T.) and you'd be surprised the number of times we've seen this same thing happen and have to stick a pin up its R's (😂) to get them to work again.
Sorin well done, quick question , I have a hp laptop not charging the battery ,at the battery terminal when connected to charger, have 12v down to 3v pulsing, could it be battery is no good or low side mosfet or bq chip, or not talking to super I/o, Regards Jim
I had two separated and completely unrelated issues with my current desktop PC: First: Bios wouldn't detect any Hard Drive connected to the mother board, it would boot a Live ISO from a USB for some reason, and not only that, I could mount my drives and see all the files... After a very long and stressful day, out of desperation I pushed the "Clear Cmos" button on the motherboard, and the problem went away. Second: Few months later. 20 minutes or so after being turned on, the screen went black and the system froze no matter what I was doing at that moment, consistently. after a few minutes of trying a few things I went straight to reset the Bios. Problem solved! Lesson learned, always reset the Bios first.
Whatever they call “BIOS settings” these days stored inside a SPI Flash chip with UEFI firmware. I guess firmware manufacturers implemented special procedure to clear (ignore) specific block inside firmware, when RTC clock battery removed
I would not call this "corrupted bios". that's when you have to reflash the bios. pulling the battery is just a cmos settings reset. I don't see this kind of issue stopping the EC and the charging circuit from doing their job so maybe u just needed a proper charger
Great video again my dear friend!!! You have the fans on hand... Sweep the dust from the casing and blow the fans a little bit just for me ok? :P i hate laptop dust
The Precision 5510 is a crappy laptop. Battery time can be measured with with a clock missing the hour hand. All DELLs have an effing ultra-miniature connector for the backup-battery. Those that have one, that is. (One DELL Precision in my organisation was actually delivered without backup battery, which we didn't find out before the user fully discharged the battery) I REALLY, REALLY hate that connector. If the main battery is completely discharged it will NOT boot. And will usually switch off almost immediately after you switch it on. In these cases it's usually enough to leave it off and charging for 15 minutes. Also, it's Precision, so the Graphics chipset is made for technical work, not games or other 'regular' graphics intensive work. Most users, when they get the 'unknown charger' message will select to not be alerted again. Then the battery dies in a few months as the machine doesn't charge the battery while switched on. (The machine switches off charging and may even slow down the CPU in order to save power so that you don't get a Brown-out) This was very common when we went from HP to DELL, and didn't manage to collect all the old PSUs, because they have the same voltage and plug.
Hello, remove the battery first. This is an excellent way to demonstrate how a half-educated electronic guy can create three problems out of one. Imagine me, who is illiterate in electronic recording, and my self-fixing TV or projector. A computer contains a "logical" part beside the hardware...
yes, but I believe newer MB's have a bios button, like my workstation, which will reset it. Mine also has a dedicated usb port for flashing the bios. So a lot has changed, I'm not sure exactly if the reset button takes the place of removing the battery, but when I built this that was my understanding of it
So how should I replace an M2 SSD on a Dell? I've been building computers for two decades but I rarely take apart laptops and I want to upgrade the M2 on my Alienware.
This is why I hate Dell; they do stupid things in the BIOS. Years ago I had a DELL USFF where I upgraded the CPU - which the BIOS was fine with; but I later upgraded the (crappy, noisy) cooling fan with a Noctua, to handle the extra power. The BIOS didnt like that at all - but rather than give a pissy message - it just decided to switch off the CPU cooler entirely - cooking the new CPU. Fuck Dell.

Dell support usually goes through procedures like holding the power button for a full minute, I wonder if that would have worked in this case.
Sorin with his magic hands made a miracle and the laptop riched life again :) nice job

Made me laugh and smile!

You did not check the CMOS battery voltage, if it's low, the job may return sooner or later.

what? from the main battery itself?
@@sanjeet5 yes
glad this not happen to me when I upgraded the m2 to 4tb in my tuf 17 inch gaming laptop I paid £1k for.
Nice one
Simple fix but as you and many others thought pch gone. Interesting that usually dont need bios to boot laptop or is that not the case?
Ive had a few Dell Desktops with similar problem. I removed bios battery ,restart and it comes back up.
Hi, with 10V battery, why it's not charging?
is that bios or rtc reset?

From my experience with Lenovo/IBM laptops I always suspect the BIOS and cmos settings when replacing hardware.
Sorin, you have magic hands and a 6th sense to solve issues! 73's de ON7OFF. I really hope to meet you on the band one day.
Why didn't you clean all the dust under the fans and the fans were clogged with dust need cleaning?
Un do what the customer did, Remove the SSD. Maybe it's loading down a date line .I'll continue watching.
That won't fix frozen BIOS
Did you put in a new Bios Battery?
Hi I have an HP Notebook 250 G5 is it possible to mount a graphics card externally (egpu or exp gdc laptop) thank you in advance

Hello🤝 pizza 🍕🍕🍕
The Precision 5510 is a crappy laptop. Battery time can be measured with with a clock missing the hour hand. All DELLs have an effing ultra-miniature connector for the backup-battery. Those that have one, that is. (One DELL Precision in my organisation was actually delivered without backup battery, which we didn't find out before the user fully discharged the battery) I REALLY, REALLY hate that connector.

(The machine switches off charging and may even slow down the CPU in order to save power so that you don't get a Brown-out)
This was very common when we went from HP to DELL, and didn't manage to collect all the old PSUs, because they have the same voltage and plug.
