Hi there, I have a Toshiba Equium A300D-16C laptop.

It was fine until now...

When I press the power button, my laptop turns on but the screen remains black / off.
HDD indicator doesn't flash or anything ... ( in case this helps )
I've also tried to remove the battery, hold the power button for 30s and plug the power cord back in... Same thing laptop turns on but screen is black.

I tried to connect my laptop to my PC's monitor using HDMI cable but no success... Laptop turned on but my pc's monitor was showing nothing.

I haven't changed anything inside my laptop or unscrewed it.

Any help would be appreciated.

Many thanks,
Rejanu.

If this will help: I quite often kept my laptop on the bed/pillow so it may have something to do with overheating or something.

How did I get to this point:

Yesterday my laptop was fine, there was nothing wrong with it... I switched it off at night but when I tried to switch it back on this morning that's where I faced this problem.

I'd say you have no choice but to take it to a professional for diagnosis. It's most likely that an internal surface mount fuse has blown as this is quite common. Unless you are an expert on surface mount components, I doubt you will be able to find and replace it yourself.

I shut my Toshiba laptop off and 1 hour later tried to turn it back on. The laptop comes on but it has a black screen. I've unplugged and taken the battery out, held the power button down for 30 then 60 secs, but the screen remains black... Help!

Spamming different threads is not going to get you the help you need. You need to follow my advice in the first thread you posted in!

mainly black screen problem caused by RAM (if not bios sound). Else it may be you motherboard problem. if got sound can check online to get answer

try this just to see if anything will happen.
boot-up or power-up and start tapping the F8 key let's see what happens.

when you turn it on do you hear anything running like the harddrive, cd-rom, fan, etc.?

you might have to take the HD out and reinstall it.

it could be your fan, memory cards, power supply, harddrive, or just the monitour itself.

so let's try a few things before you start getting into the pocket.

I tried to boot my laptop and even tried with its battery and power supply, it's still not working and last I used it it was working absolutely fine! I can't find any solution that works on my hp probook 4510s . Can anyone help me please?

My PCs screen beeps and goes black at the boot, turns back on to show that windows is starting up and beeps, then turns black again, but thhe screen is still on (running or whatever). Restarting, opening the setup menu and turning it back on (beeps) and off worked before, however, I'm not sure because someone else did it, but when I tried it, it didn't work again..
so..

The best thing to do should be to delete everything on your hard derive (hd) because it's a virus, or try system restore (before you got the virus or the last time it worked) if it is able to.

I'm having someone delete everything off my hard drive for this (should work) and have to reinstall everything. Oh well..

Good luck
