IBM T 42 - Not starting

Sep 14, 2008

-   Same problem here with an R50e. I asked my boss if I could take it home. He said yes and I took it home. To my surprise the machine booted and worked for almost two days (with several reboots due to windows updates, benchmark tests, and burn in tests that stress the CPU and memory.) Now the Problem is back.
I guess It has to do with large SMD components on the motherboard that become lose when the motherboard flexes. A known problem

The only thing that starts up are the LEDs and the CPU fan.
I think they are (left to right)
NUM CAPS HDD POWER BATTERY SLEEP.

• When pressing the power button all LEDs light up. (except for the wlan indicator which is a bit separate)
• After about a second BATTERY and SLEEP will go dark.
• After a little more than a second BATTERY comes back. (If I pull the battery and only work with the AC adaptor the BATTERY LED will stay dark after the initial stage)
• Half a second later NUM and CAPS go out.
• HDD POWER and BATTERY (if a battery is presend) will stay lit.
  
  

You can hear the fan spin up quite a bit so I guess the CPU is running at full speed.

Notes:
The ThinkLight does not work. Usually It does as soon as the BIOS is done with the POST (power on self test).-   henrik-fixya
