I've just tried, it's kind of stuck in a boot loob, power + esc + caps are light, and I see the screen flickering once and the fan spinning and it restart few times, then it's back to my original state, only power button light.
If I clear CMOS, I'm back at the loop boot state.
It detects if I put no RAM (got the beep error code)...Leave a comment:

Surface Pro 4 X911788-008 - No boot
Hi,
A friend bring me his Surface Pro 4 X911788-008, it won't boot at all.
It charges, battery is fine, cpu and ssd are heating when I press power (I can shutdown by pressing 15s power).
I've mesured voltage of all inductances after pressing power, everything is fine except 2 that are at 0v, I think they are used for iGPU.
There resistance is 2.5ohms.
I've found schematics and board view [URL="https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/schematic-requests-only/86286-surface-pro-4-x911788-009-schematics"]here... -
Yes, and I've got bad luck with theses keyboards:
1st one (the original) : was working but lot of keys was destroyed by last owner
2nd one (refurbished) : not working at all
3rd one (refurbished) : worked maybe 30mn, then I started having issues and finally broke
The 3rd one was the worst as the laptop cannot boot at all when plugged in, even when shorting power button....Leave a comment:

Hello, I'm back with this laptop, I decided to dump the EC but before, just tried to boot again, and the keyboard lighted up and fans spinned, and no picture. CPU, GPU and PCH was warm.
I've flashed back original BIOS, but cannot boot (sometimes not at all, sometimes only keyboard light and fan).
Power on doesn't work with keyboard, I have to use a tweezer on the connector.
If the keyboard is connected, I cannot power on, even with tweezer.
And finally, after charging the battery for a while and booting withtout the keybord (I only let backlight ribbon connecte),...Leave a comment:

Here is my dump, but i dont know which one is the bios or firmware as there is 2 different chip, MX25L25673G and MX25V8035F so I've dumped both.
Thanks for your help !

SAPPHIRE NITRO+ RADEON RX 570 4GB - No picture
Hello,
I got a SAPPHIRE NITRO+ RADEON RX 570 4G that has no picture.
I see no dmg on the board.
Fans and RGB are working.
I can see the card on Windows with an other GPU, but with an error in device management.
When I try to install last driver, it freeze.
I've tried to boot on Arch linux to do a meme test, and it freeze at boot.
Here is my resistance measurements :

Quick update and end of this thread. I've got some help from a discord channel, and we figured out there was a short on the anode of the replaced diode.
It's certainly a diode for RTC_VCC, and after injected voltage, I saw the PCH heating , so dead motherboard :')
Thank you anyway.Leave a comment:

I've done measurements on motherboard coils, hope it'll help, see attached picture....

If you have 0v at every pin, battery is certainly dead anyway.Leave a comment:

I don't have schematic, just remove battery and measure voltage between ground and all other pins.Leave a comment:

Just measure battery voltage with a multimeter. Or if you can boot in OS, you can check if battery is dead or not.Leave a comment:
