Hello, I have a Dell Latitude C510 Laptop.When i press the power button the lights come on for some seconds and then goes off and has been doing like this for days now.So i had to remove the RAM and other cards one after another but still act thesame. Pls what can i do now help me okkkkk.

I'd test the ac adapter, make sure its putting out the proper voltage. Try powering on while only on ac power (battery out), and try with only the battery.

it sounds like a short or cpu o/heating

does the cpu fan run and is it clear of dust

Madcatz

I agree with dai, sounds like something is shorting out or causing feedback in power. You said you removed RAM and other cards, which other cards?

Also if you havn't tried this, remove the hard drive, cd drive, wireless card, modem card, touchpad cable, hotkey cable, take out/unplug everything you see, except for the dc in jack, processor and fan, power switch, memory, and lcd cable. see if it stays on, if not, unplug the lcd cable and try it again. Still turns off after that then i'd look into replacing the motherboard first.

Hi Madcatz.
I tried everything you just say b4.When i said i removed all cards i was talking about hard drive, cd drive, wireless card, modem card, touchpad cable, hotkey cable.and even LCD cable has been removed but still to know avail.pls help me don't want to believe its Motherboard fault.bcos no money now to get one.

if you have nothing hooked up to the motherboard, just processor, fan, and the power switch, do any lights flash or any beeps? or does it still shut down?

if it still shuts down, then you need to start replacing things. first and cheapest is the power switch. if its stuck and not "popping" back out like it should be, the motherboard will think your holding it down and will shut off in 4 seconds, like your describing.

if the power switch doesn't fix it, then you could see if you can get ahold of another processor that will work in the motherboard, from another C510, or dells website should have a list of what processors were availble and tested to know they work with your unit.

Does the CPU fan run? Or it doesn't try to start before it shuts off?
