Find hardware causes.

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!?

Sorry to tell you that this problem is not caused by the bios.

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?

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!

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?
