Question about Computers & Internet
L20 197 model (celeron) laptop.
Often refuses to boot when power switch pressed.
Replaced motherboard with another good unit. Replaced celeron CPU, and tightened screw correctly. Changed RAM, tested Ok.Installed XP from scaratch all drivers etc worked fine.
Shut down suddenly and won't reboot.
When power switch pressed middle led lights up bot no boot. Soemtimes, the fan whirrs and it boots normally and works normally. I suspect the CPU/socket area. Anybody have any ideas?
In 19 years of working on computers I've seen 1 bad Intel CPU and it still worked it just showed the wrong processor speed. I'd eliminate the CPU being the problem. Generally if you have a bare system with motherboard, ram, keyboard and video and they turn on the system is good. The video may cause a crash if it's bad somewhere in the bootup process going into windows but it shouldn't stop the initial bootup process. The area I would likely suspect is the hard drive. If the arm inside the drive that controls the heads is loose it can cause the drive to read sometimes when cool and then to start slipping and not read when the system is warmer. If you can get into the bios there should be someplace there to check your temperatures and voltages. Those might be a suspect area. If the power supply isn't delivering the proper voltages or the CPU is getting hot could cause problems also. I'd like to hear more about what you're seeing on the screen when this system fails to boot. Does is show the ram countup, system devices and hard drives as detected in the bootup process? Or is the screen just blank. When it doesn't boot does the hard drive light blink continuously?

Tips for a great answer:
Your computer has no power at all or cannot boot properly. In some situations this can be caused by an external device or an electrical problem. This can usually be solved by removing all external devices and resetting the power supply.
Instructions for laptops:
1. Disconnect all external devices you have.
2. Unplug the power adapter from the laptop.
3. Remove the battery pack from the laptop.
4. Press the power button and hold it for at least 15 seconds.
5. Reconnect the power adapter.
Do not yet reconnect the external devices, they should stay disconnected. Do not yet reseat the battery pack.
6. Switch your laptop on and test if it boots normally and watch if the power LED lights up.
7. If the power LED still does not lights up, continue with the next steps.
8. Disconnect the power adapter from the laptop.
9. Press the power button and hold it for at least 15 seconds.
10. Reseat the battery pack. Do not reconnect the power adapter.
11. Switch your laptop on and test if it boots normally.
Solution 2: Unplug and reconnect System Hard Drive
1. Unplug the power adapter from the laptop.
2. Remove the battery pack from the laptop.
3. Unplug and reconnect System Hard Drive. This is normally accessible by removing a panel at the bottom of the laptop or removing the back enclosure (see User Manual).
4. Reseat the battery.
5. Switch your notebook on and test if it boots normally
