Re: P52 Bios 20m9 Need
Tried to change RAM etc. nothing worked. With the old bios the fans are spinning and I get beep codes if RAM is missing. So I think there is no hardware issue!?Comment

Re: Lenovo P52 not powering up
I´ve flashed again the version attached. I´ve got it from this forum, but don´t remember the exact post, I´ll try to figure it out.
With this BIOS, the Laptop is starting. I get no HDMI output, but I get the error code 0288 for Display Error, wich is fine, because there is no internal display attached.
Also I get 4 short beeps.
The system starts directly when I plug the charger. No blinking on power led. Power off and power on again works with the power button.
Fans are spinning and the system stays on.
I think the hardware is fine, otherwise the laptop wouldn´t start?
I´ve checked the bios with ME Analyzer, it says:
Note: This CSE ME firmware was not found at the database, please report it! (See attachements)
Any ideas on this?Attached FilesLast edited by Clarify4082; 09-18-2023, 02:52 PM.Comment

Re: P52 Bios 20m9 Need
Hello again
,
checked everything hardware related, I think it´s not a hardware issue. (See: https://www.badcaps.net/forum/showth...&highlight=P52)
I´ve tried to extract a fresh bios from the original Lenovo file to flash this, but Innoextractor don´t give me a .exe or .cap file.
Can you extract a fresh bios from the original installer (attached)?
thanks!Comment

Re: P52 Bios 20m9 Need
Thank you!!
Finally the spare LCD-Screen arrived and I got the laptop working with the bios attached (working_20230919).
There is one thing that needs to be fixed.
With the running bios (working_20231909), everything works fine but it takes 30 seconds to get to the Lenovo boot image.
So I think this is because of a bad/missing/wrong ME.
But if I patch a bios you provided with a new/cleaned ME the Laptop don´t power on.
If I try to clean the ME on (working_20230919) I get an Error in the intel flash image tool (see attachments).
Can you please have a look again?Attached FilesComment

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 an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
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...
