Question about IBM NetVista PC Desktop

I turn on my PC than half second turn off itself

Ok I got this IBM machine when I try to turn on, it turns on for half a sec and then it turns off. It will just keep on trying to do the same thing if I leave it without unpluggin the power. First I thought the PSU was bad, so I changed that but that wasn't the problem. I tried to change RAM as well... could this be the motherboard problem? My assumption is it is but I do not have another motherboard to test it out... anyone had/have similar problem? Thanks

It could be a motherboard problem, but, this may sound silly, but it could also be a stuck up power or reset button. I had this experience with a desktop pc where the power button got stuck in its "press" position. Try removing the connection of these switches from the mboard and use a metal screw driver to act as the switch by momentarily shorting the power switch connection on the board.

--you can also check the cmos battery of the pc. These newer boards would refuse to even power up if the cmos battery are drained.

Laptop shuts down a few seconds after starting


My IBM is about the same as yours and did the same thing. It turned out to be a CPU Cooling Fan. When you turn the laptop on, try to look in the air outlet port and see if the fan is turning. Another possibility is lint and dirt around the fan. The unit has a temperature sensor that will shut the machine down on a "Hot CPU" signal.

What does the half moon lit up mean, No screen.


The half moon usually means the computer is in SLEEP MODE. Normally, pressing the spacebar will wake the computer up but I have noticed that sometimes, the computer can get "stuck" in sleep mode. If that is the case, you can hold the power button down (until the power turns off and the moon disappears). Wait a few seconds then hit the power button again to turn the laptop back on.

T42 Turns on for a split second then turns off.


OK. What you can do is to take out the battery then the HDD the plug in the unit and try to start it
If is doing the same thing definitely you got a bad SODIMM. If you have two of them try removing one and another to see which one is bad.
When you take out the HDD and memory remember to dismantle battery first and disconect the main.
This is the way to avoid damaging your memory and HDD

Startup problem


try pressing F8 on start up and getting into the safe mode and highlight last known good configuration. If still no luck try this:- Only other solution is to remove right side panel of pc and locate the JBAT1 terminal and move jumper from pins 1-2 to pins 2-3 for a few seconds and back again. Turn on pc and then hopefully you can access the bios to set the time and date and save settings then re start.
