IBM does not start (load) (urgent)
I have IBM 600X. (its urgent please reply)
One day system hanged. I restarted. And it never did.
Now the situation is it does not start.
1. Processor fan runs at high speed for few seconds then goes slow.
2. Power light and HDD light it alwasy on (green).
3. No sounds.
4. No display at all. Complete black. Not even backlight.
5. No display even in external monitor.
6. No display even without RAM, HDD, CMOS Battery.
Few findings when i opened it....( i have been able to solve few minor problems myself...so don't mind opening morover M BTEch Computer Engineering...)
When i opened it for the first time.
When i removed the Cmos battery ... then tried giving power.. suddenly displayed came and few error codes ..related to no keyboard.. no battery. no time and date (its obvious as these where out)..
then again i switched off.. now there is no display even without battery ( CMos) (also no display with all components).
then i proceded forward.. removed cpu fan.. again display comes back... but the same problem. from next time.. no display or even no activity after few seconds even without fan. ( here i didnot leave my laptop for longer time as there is risk of heat.. without fan)
i am not under any warranty.. so please don't suggest to take to IBM center.
NO other good repair centres here..
so please suggest few remedy..
M comfortable with any hardware fixings...
its urgent please reply
