I have developed a new issue with my old Samsung R40 laptop. It will now always hang while running the BIOS. This was not so when I got it earlier this year. The computer will usually not proceed to booting the operating system. If I enter BIOS setup, I am able to adjust at most 1 setting if I am quick, before the computer locks up and must be power cycled.
If the BIOS does not hang, and starts booting into Windows XP, which happens about 1 in 5 attempts, the system is completely stable under load. I can hear the hard drive powering up and seeking, so it's not that the system is failing to read from disk.
To find the cause of the problem I have so far:
- reset BIOS to defaults, confirming that it really happened
- disconnected all peripherals and cables
- disconnected the hard drive
- removed either one of the two memory modules
- disconnected the WLAN radio
The BIOS would always hang in diferent stages. Sometimes on device enumeration, sometimes right after entering setup. I was able to restore essential settings one by one.
I am in peace if the machine is dead. I'm just kinda curious how is it that it can work in Windows stable in this condition.
