Re: G500 - this is not a valid windows machine?

This sounds like the Windows ID key was deleted from BIOS.  You may need to contact Microsoft Support to obtian a replacement Key for your Windows Distirbution.  Try booting from a Linux DVD (Live DVD) to see if the computer works as it should.

 

If hardware is working under Linux / Windows but you get this message it means the Windows Key has been lost or compromised.

No worries.... Also - the Trusted Platform Module may have lost its data as well, this can be fixed by the Windows Key replacement process most of the time.

If your notebook or computer is having a similar problem, we would need more detailed information to move forward.

Re: G500 - this is not a valid windows machine?

Yes , you're correct.
my computer have the same issues.
I got a hold on the IBM Hardware Maintenance Diskette and after many failed tries .. I was able to read and write UUID-serial-etc.. .
when I reboot the computers multiple times, sometimes it will lose all the info again (UUID all in fffffff. )
I want to:
- locate and reflash the EEPROM and the BIOS chips. maybe via using an SPI programmer
- if that fails (due to a physical damage) , then I want to replace the chips (where can I buy them?)

Re: G500 - this is not a valid windows machine?

In most notebook computers the EEPROM is not socketed for removal / replacement. This is mostly due to space restrictions imposed by thin and lightweight designs that have become the norm, much to my regret. I do miss the older more durable designs.... If not socketed, then it requires a solder removal tool, and a very steady hand. Most often, the process of removal usually causes more damage to the main system board and will result in a very costly paper weight.

If you are covered under warranty, the best route to resolve this type of issue is to have the system board replaced, as it will carry updated ROM bios and not need to be re-flashed.

Also - going forward with EEPROM replacement usually will void the warranty (if present) as this is not considered to be a FRU or CRU item.

Also - in the linked photos, some of the other SMD's are showing damage, indicating some other issues may be also causing the system problems you are reporting.

Re: G500 - this is not a valid windows machine?

indeed.
I want to fix this issue myself.
any comprehensible guidance on how to reprogram or to replace the damaged chip? (tools, probes, connectors, etc..)
