I asked for the serial number because it`s one of the forum rules to post it, if it is available https://www.badcaps.net/forum/troubl...before-posting
Cleaning the ME firmware should fix your bios problem, do you know how to do that ? https://www.badcaps.net/forum/troubl...22#post1622422Comment

Not sure what the go is with this one. I had left it doing final Windows 11 updates, when I came back to it later had high fan spin and forcibly turned it off with power button. Not sure if this was a bad Windows F/W update or not. Now all I get is 7 orange blinks on the battery light when the power is applied either via barrel adaptor or USB-C. This doesn't seem to line up with anything in the manual. AFAIK, it was already on V1.31 BIOS which is supposed to be the latest.
One other weird thing is it is flattening the BIOS battery after I just have replaced it but I think that is a side issue. Attached are the dumps for BIOS (U365) and EC (U366). S:N is 5CG8100CT2. BIOS looks ok in UEFI tool.
Edit. Was checking the CMOS battery issue and found 12 ohms on P3V3_RTC and only .75V present. Usually I find these issues to be PCH related but there quite a few things on this rail.
Edit 2: Bloody cap! I put 3V onto that rail and it finally went full short. Was C4766 (1uF 0201) just on the other side of the board from the CMOS battery connector. Now it starts up.Last edited by reformatt; Yesterday, 11:55 PM.Comment

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice... -
