7:04 though in theory it should be fine to hold the cooler to carry the board, i dont like it. it's still tension on the board itself.

1:15 OMG what a sick price!!!

i have a dell optiplex 3070 who cames without the power supply and when i plug the screen in and try to turn it on it doesnt beep but the power led comes orange then stays white the screen isnt showing anything maybe its because of no ssd inside of it

Try putting it in an oven at 400 degrees for three hours, then dropping it into a bowl of chilled ice water with ice cubes. Let it dry for a week flipping it over every two days. If it still doesn't work try changing the cpu pinion. If no success then it's probably dead. P.S. Quit posting useless clickbait.

Sorin from Electronics repair school has discord that has many many many bios images and also a great repair community for laptops. They may be able to help you as well.

Please send the broken machine on to another youtuber! Th3c0der (or however it is spelled) in the UK would be able to replace the CPU. Not that there is commercial value to doing that, but having him swap it out in a video will be good content, collaboration and it might just prove your diagnosis correct.

Getting all the voltages on the various rails is a good way to diagnose some possible problems. Don't forget to also find the on board fuses and 0 ohm resistors between the voltage rails and the actual power using chips. You have found a few, but you did not explicitly say in the video you checked all. You may have done so off camera?

You say you have a scope. I would try and find the data line for the BIOS chip and put a scope on that when powering on to see if the computer attempts to boot. If it does, you should have fully functioning processor, bios, RAM and such.

If a "laptop" responds to the power button, in general, the SIO chip is functioning, since this is the thing that switches the computer from standby to on.

7:00 i have seen other reviewers say same thing about updating, i would hope that by now, 6 months on they have corrected with updates.

Did you ever try this using a USB display adapter?

nice! just love to see this kind of tinkering.

Should I buy this gpu for blender?

I just bought one like this and it would not recognize my 4k monitor via the DVI port. Wound up purchasing a video card that supports 2560x1440 and voila!

If the 4th phase was not controlled or broken, the fans would not spin. The 4th phase can also be the turbo booster, which is normally turned off. The 1.8V phase is probably the PCH, not the IGPU, although the GPU is supposed to be in the PCH of the N100. Test all your phases in ohms mode. If they are not close to 0 ohms, say 20 ohms, they are fine. If they are lower, you can confirm that the CPU is dead by applying voltage to the phase (0.5 V, 500 mA) with some alcohol on the DIE. If the whole area gets hot, the CPU is fine. If one corner lights up, the DIE is broken. My guess is that the N100 is fine. Instead, I suggest you focus more on the 3.3V PCH rail, as this is likely to be the problem. Test pin 8 of the bios SPI IC, which should bring 3.3 V. In most cases in these small PCs, the ram SPD SPI IC is in parallel to the bios SPI IC, both powered by the 3.3 V rail of the PCH. My guess is that the ram swap triggered voltager on the SPI lines of the bios IC (through the rams SPD / SPI). Try dumping the bios and open it in the UEFI tool and look for any errors. Also reflash the bios with a clean (ME) dump. Since the pc turns on shorly and the fans spin, my guess is that it 's somehow bios / SPI related.

for the pc that has the graphics problem, couldn't you use a external graphics card setup, you can get external graphics card dock, maybe that would fix that problem.

Hi, usually, SMD bridges (0 Ohm resistors) are black (which is the resistor color code for 0) and bear at least a '0' on them, but the one of the Zulu might have been soldered upside-down or was unmarked. Almost everything smaller than the Mini-ITX mobo format, if not a SBC, can much too easily fail, essentially because it is too much heat for a too small volume and SMD are so small that it is very easy to miss a lose/missing one - once again, this is programmed obsolescence :( Before all, find a way to test the RAM.

Reguarding the latter part of the video - is there not any way to attach a buzer to the motherboard for beep codes? my Desktop pc definitely boots CPU, RAM, GPU and has bios lights to show this stage step through of the post process

was quite scary when you put in that 10k ohm resistor, if my understanding is correct if that was r2 of a voltage divider, you could end up diverting more voltage towards the vOut of the divider circuit?

You need to invest in a hot air rework station for dealing with surface mount devices. Also look for tin whiskers when looking at the board when looking at it through the microscope.

Halo bro i am asking that the cooler master 550w psu (80plus)(non modular) can connect to this gpu

My similar Beelink refused starting due to the glue under BIOS battery became conductive and shorted IO signals. After cleaning it works fine again.

If the Blink system supports a direct flash BIOS image it might be worth while to see if maybe it got corrupted and just needs to be flashed with a working image. It's logical that something like that would happen if the BIOS were active because their normally connected to the memory in that the BIOS image get's written to memory when the system boots. It does this because the RAM is generally faster than the BIOS chip. At least that was the case for older systems. Point of the matter is this. Attempting to flash a good image to it might be worth a shot. Like you said, "it's already broken."

dude, your bios is lost

People, do not buy no name chinese electronic junk.

I did something similar with one old monitor, the problem was not in the alcohol you used to wipe the case, but in the age of the paint, which had lost its strength, after that I told myself that I would never wipe 10 years year old things with alcohol (and I used ethyl, not isopropyl, it is even weaker)

I am wondering why write speed is that of a single drive. With most RAID, data is written across all the disks, so the more spindles you have, the faster the writes. Same with reads, obviously.

Blah blah blah

THERE'S A LOT OF MISSING KNOWLEDGE IN THIS VIDEO!!!!! +The youtube playback, you have to force H264 because old devices can't play VP9 +The sound distortion might be the driver? (you helped me discover this). I have a Dell that sounds exactly the same in an updated Windows 10, but was totally fine in Windows 7... hmmmm, I'm going to see if the headphones are any better. +and 4GB?... I have an older system nearly identical, an Inspiron that tops out at 3gb... You're lucky :) Kinda wish you put the specs in the video description.

wow amateur

The burnt resistor was probably a zero ohm resistor used as a fuse. That should be replaced with same part.

Neat looking build. Used SAS drives are the best way to expand your storage on a budget. I just picked up a bunch of 14TB drives for $85 each. Hoping my new build will solve my storage problems for a bit... 🤪

"Finding schematics for __THIS__ computer was never going to happen" - i like the approach :), sad but __TRUE__ ;) Thanks for pointing that "CMOS" reference - cmos technology was a great break in the 70s but nobody now remembers how great it is, i dont even remember when have it started.

Used enterprise drives are a good cheap way to get some storage on the cheap. Some sellers even offer a 5 year warranty on the used drives.

Could try Haiku OS on it.

You don't have to use the hdmi for the screen , try useind usb or Bluetooth

Hey man ive been here since almost day one and always enjoy ur videos just wanted to ask if you think you could do a series of videos on servers/homelabs and nas solutions how to set it up what you can do with them etc etc? I want to start my own but dont know what to do and how to do so really and cant find anyone else pleasant enough to listen to

Umm no.

infrared camera?

Stupid question... Is there any motherboard speaker output jumper on that motherboard? If there is, and you can hook a small speaker to it, it may give you some diagnostic beeps.

that'd be nice to make a comparison with linux windows 7 and windows xp trying to run the same range of software to see how much bloat they add/how good the drivers supports are

The background music at the beginning sounds like the old skype ringtone!

Install LM XFCE edition and it will fly.

Could I ask you in the ikea unit you have components in orange boxes where did you get those from?

For some guy like tihs Carey that works with computer over the years, not disconnecting the power from the mini pcs... is a crime. Obviously, something will break no matter which platform. I once installed a RAM module when the power was still plugged and ended up burning the slot. ALWAYS remove power/battery when replacing RAM modues or other parts.

low end cisco has been rubbish for over a decade... avoid

It may be an interesting idea to try a lightweight Linux version, just to see how it compares.

interesting

My guess for the issue is probably heat related.

Nice video thank you and a reasonable nas upgrade. Can explain (maybe in another video) why the write performance is so low? I was always under the assumption that raid 5 would increase read and write speed with the number of disks in the array.
