Thank you for your help, unfortunately, still the same problem: 2 amber 3 white blink. It suppose to be RAM related, but pretty sure it's bios, any suggestion?Leave a comment:

Hi Piernov,
Thank you for answer, iGPU work when he's a low frequency/resolution like in bios, memtest, and windows without driver load, but as soon as driver load, it crash directly.
I know nothing about iGPU, is there a way to modify his frequency profil in bios or something like we can with video bios?Leave a comment:

Acer Nitro 5 AN517-52-54PM no power disable iGPU possible?
Hello everyone,
I have this laptop came in with no power, shorted main power rail, after measuring resistance on coils, found out that VCC_GT was short (high side MOSFET part of the dual MOSFET was shorted)
After replace the MOSFET, laptop came back to life, pass memtest without any issue, but whenever I try to boot Windows 11 SSD or Windows 11 install from USB, laptop freeze I guess iGPU is partial dead since he received 19V when MOSFET got shorted.
So the question is, can we disable iGPU like hardware mod or BIOS mod?
Thanks by advance for your interest... -
Re: Asus R702UA dead (missing voltage)
Nice job, and thank you for the picture, I should have post one myself back in time.
Edit: if people ask about the value, it's something like MLCC 1uF 6.3v 10%Last edited by alderick; 11-08-2021, 09:33 AM.Leave a comment:

Re: Asus R702UA dead (missing voltage)
Hello,
I don't remember which side of the board that cap is but you can find it with multi meter in beep mode, one probe on JRST2402 (RTC_RST side not GND obviously) et try all caps around the SOC.
Reprogram bios is useless in that case, the only faulty thing was the cap, just find it and replace it.Leave a comment:

Re: Gigabyte GA-Z170X-UD3 no post
I removed the PCH, the short on MB is gone, so it is fried like you said.
Since I don't have a BGA rework thingy, I'm gonna trash the MB.
Case closed, thanks for help.Leave a comment:

Re: Gigabyte GA-Z170X-UD3 no post
Hello, thank you for the answer.
Without CPU same 1.3 ohms, and with only standby, it takes 3W at main socket, PCH warm but not as much as when I try to start MB.
PCH fried anyway so.
Can't change that thing, I should trash it I guess.Leave a comment:

Gigabyte GA-Z170X-UD3 no post
Hi guys,
Recently my main desktop just die in the night (I shutdown before sleep), no idea why, already buy a new MB and CPU so nothing hurry.
The PC try to start but no post and code 49 on MB debug digit thingy.
The PCH is hot, CPU cold, 20W on main plug.
On PCH package there is some cms caps, 1.32ohm is it normal?
If i bring power on rail one by one, both 5V and 5v stb take power, ~0.6A.
Any idea or thing to check?
Thanks a lot.
Edit: I did backup M_BIOS and after copy B_BIOS into M_BIOS chip, without any cha...Last edited by alderick; 09-02-2021, 05:09 AM. -

Re: LA-6911P discrete to UMA
Hello,
I would like to know if you had any success with that modification?
I have the same board with a dying GPU and I want to go to UMA too.
Thanks.Leave a comment:

Re: Acer E5-575-39FE no voltage on battery
No, can you tell me how please?
If you mean the switch under the laptop we can reach by a small hole, I did check and it's working fine. 0.2 ohm when pressing and open circuit when release.Last edited by alderick; 11-30-2020, 09:01 AM.Leave a comment:

Acer E5-575-39FE no voltage on battery
Hello guys,
Laptop have been dropped, broken screen and battery had no voltage on connector.
I replaced the screen and it's ok, but still no voltage on battery connector, 16.91V on cells, which is fine for 4cells battery.
I ordered a brand new battery from Acer, same thing, no voltage on it's connector.
Is this a MB issue?
I did some measurement on the bq24780s, but since there is no voltage on battery i'm not sure it's any help?
Thank for reading.
