    How old is it? Does the cooling fan(s) spin rather loudly or very quickly? It sounds as if this issue is heat-related. Otherwise this is an issue with a Virus.

When the laptop freezes up on you does the keyboard or anywhere on the top cover feel very hot if so check to see if the fan is even blowing, if it is blowing then its possible there is dirt on the heatsink fan that is blocking the air flow and thats causing the overheating. You would need to take apart the laptop to get to the cpu heatsink to remove all the dirt.

if the fan isn't running at all then you would need to get a new fan.

If the fan is running and there is no dirt or debris near the heatsink then that means the motherboard is not reglulating the voltage properly and the motherboard needs to get replaced.

if nothing is feeling very warm or hot to the touch and the system is locking up then the hard drive may have bad sectors and the hard drive would need to be replaced.

Dell latitude c640. turned on this morning and got the caps light to blink a few times and cd drive to power up then nothing. Just turned itslef off. Has been working fine until this.


several reasons why this will occur:

1) battery is not fully charged - you might try rebooting with the computer plugged into a wall socket.

2) computer's main power supply has been damaged and needs to be replaced.

3) virus - though with most standard virus' , you can still boot up, there are a nasty few that will wipe your entire computer including the operating system.

Dell C640 Turn On Problem


Probably an overheating problem. The best thing would be to disassemble your notebook, and clean the heat sink. If you're not experienced with this kind of things, don't do it. You can try to use a vacuum, or take it to a specialist.

This could be caused by a number of thing, bad battery, bad power supply, bad memory chip, bad processor, and a bad component on the motherboard. Start by checking the output of the power supply with an ohm meter. The output rating will be on the power supply or you can go by the input in the machine. Then try starting without the battery. Then remove the memory and try with one chip then the other. At this point, if the problem persists, you will need to take it for a professional diagnosis. They will be able to test the processor and motherboard to find the exact problem component, and tell you whether it's replaceable.

Booting problem


Try putting the computer into safe mode by holding down on the F8 button and selecting safe mode during the boot process. Once you get to the safe mode screen and windows appears, restart the computer.

If that doesn't fix the problem you will have to restore Windows.
