Hello @ThienBui
Good morning!

This LENOVO with PCB: GS452GS552GS752 NM-C781 Rev 1.0

I tried the Vinafix bios and the PC turns on but there is no image.

With customer source bios, the PC turns on with image, boots to the system, and completes the 4gb onboard ram memtest without errors.

The problem is when I install an offboard RAM for upgrade. I've tried many RAMs and whenever an onboard RAM is connected, the PC turns on without an image.

Can you change my BIOS source and solve this problem?

I need two things.

* Remove bios password

* Solve problem with RAM upgrade.

Thank you very much.

Why are there so many problems? I think you need to try another bios first

Morning!

I told you, I tried the BIOS that is in the Vinafix post and it doesn't work; the PC does not have an image with the vinafix BIOS.

There are only 2 situations:
* There is 1 problem with RAM upgrade.
* I need you to remove the BIOS password.

Can you remove the pass from my bios?
Can you solve this RAM problem?
Please
Tks
