Re: non powering

Hi! the motherboard is dead. if the ac adapter light turns off when plugged in and if you unplug it, it will turn on, then the problem is with the motherboard. It needs to be replaced. Call Dell Tech support if you still have warranty to have the motherboard replaced or else, you have to pay for the repair.

Hope this helps!

My laptop compaq presario v6000 does not switch on but the power light comes on when the chager is on. when i try to turn the computer on it just flick the light on then back off. can anyone yep me to

The DC pin on your laptop is bent/broken/loose. Look at where your power adapter plugs in on your laptop. Get a paper clip, bend it out to make a long paper clip and slightly push its tip on the pin inside your laptop. If the pin moves chances are either the DC pin needs to be soldered down or needs to be replaced. The part is usually cheap around $10 but the labor can cost more than $50.

Have you tried the other fix? It often times works.
Remove the battery AND the power cord.
Hold the power button for 10 seconds.
Now plug in the power cord.

Magic should happen

C 400 Latitude display problem

That LOCK A sysmbol is the caps lock.

Most likely its due to hardware failure. Be sure the battery is holding a charge and the power adapter is working.

It could be bad Ram. Usually when there is nothing at all but a quick light on and off and nothing, its due to motherboard issues or hardware plugged into it. Try removing any CD drives or add in devices.

Good luck
