Hi all,

I have a laptop that has been working fine for a while and now suddenly it just will not boot at all, all i get is a black screen.

When i turn it on i do get the green power button coming on so i know there's some power but i just get a black screen.

Any ideas?
 
Hmmmm, could need a cmos reset. I've seen this a couple of time. Not the easiest thing to do on a lappy unfortunately.
You could try taking the laptop battery out and holding the power button for about 30 secs. Other than that, take the cmos battery out.

How easy is that to do?
 
It depends on the Laptop.

Sometimes the CMOS batteries are easy to access sometimes you will have to strip down the entire laptop.

There are usually guides available for the more popular models, have a quick Google around.

I'll have a look around when i had it open last i did see a battery type thing in the back, how do i know what battery is what?
 
Some laptops have cmos clear jumpers under the ram. But last one I did I had to fully strip down and unsolder one of the pins off the battery and resolder a minute later.
 
i found the big battery type thing and removed it for around 30 seconds and put it back in and still getting the black screen, anymore ideas?
 
Could be the connector from screen to motherboard. Could check that but before i'd say plus a monitor into the vga port and see if you can get a dispaly. Also might be able to sign a light on the screen to see if the backlight is ****ed.

When the laptop powers on it there any hard disk activity? Normally have a little LED blinking away.
 
Might be dead graphics card is it gaming laptop? Try to connect it to desktop monitor, does it boot to windows or just run?
