Laptop screen blank when switched on

Hello, I need help. My acer laptop won't boot up. I tried to reset it (Hold power button for 30 sec without the battery and no power) for hours. It still won't turn on.

When its plugged in, the battery LED turns on. I press the ON button, the num lock light blinks once and the CD/DVD drive lights up and the fan starts... however, I hear a clicking sound.

Could you help me find out whats wrong with it?

My dell inspiron 3537 is not starting up. It blinks the power LED 3 times and then the power LED stops blinking and stays on.

It is not showing the charger when I plug it in.
I have tried starting up by removing the battery and using just the charger, the problem stays. Since the power LED blinks when I'm on just charger mode, I don't think there is any problem with the charger.

Please help.

Hello,

I have a lenovo thinkpad and hoping someone can help ... My PC was on sleep and there was not power cable plugged in, the thinkpad red light was on last night and today I realised the power must be dead as it wouldnt turn on. I have plugged in the power cable but its still not turning on. Any tips?

Your help is much appreciated

System Configuration: Windows XP / Internet Explorer 7.0

Hello everyone. Im new to this forum so I hope you can help me with my problem. Today I was playing some warthunder when suddenly my pc just turned off. I tried to turn it on after and it wont boot. The fans were spinning loud but everything else just seems fine. Here are my specs:

Motherboard: Biostar G31-M7 TE
Cpu: Intel Core 2 Quad q6600
Gpu: Geforce GTX 260
PSU: Cooler Master Silent Pro 1000w
Hard Drive WD 160gb

From what I have read I think the problem is because of the motherboard. I think it has reached the end of its life. I have had his system more than 3 years. If you could help me I will be thankful. Sorry for he bad englis...

I tried removing the battery and pressing the ON button for 60 seconds. Didn't work.
When I boot, the screen is black. However, I can press Control Alt Delete and bring up New Task that way. The only thing I've been able to bring up (or think of) is notepad, which opens.
The laptop is an MSI GT 780 DXR running Windows 7
When I boot into safe mode, the same thing happens. I am backed up except for the photo shoot I just did, of course. ) :

Hello,

My monitor was on sleep mode (orange light) so I pressed spacebar to awake it. However, it just went blank on me and I couldn't turn it on since. the indicator light doesn't light up at all. I tried another power cable but it still doesn't work. I'm guessing it's an internal problem with the screen but I don't exactly know what the problem is. How do I go about fixing it? Thanks!
