W7S Black Screen on Bootup (Dead?)

Sometimes, when I turn on my computer, the screen is just black, even after a minute. so i would have to unplug the computer and restart it, then it would be fine. it happended a couple times... but just right now, it won't turn on anymore no matter how many times i unplug it... anyone know what might be the problem? i don't think it's the screen is dead... because it's not even loading into windows (because i cna't do anything.. i don't hear any sound etc)

is my w7s dead?

 

What are the status lights saying on both your adaptor (if it has a light) and your notebook? Any signs of life (hard disk activity, CD/DVD drive lighting up or able to eject)?

 

at first the hdd sign flickers for a few seconds, then after the only sign lit up is the lightbulb

 

The notebook power light? Does your notebook have a floppy drive? You could try flashing your BIOS, but i think that requires the computer to actually boot before you can flash it. Did you change anything recently? BIOS, Hardware or Drivers? About the only other thing I could recommend would be to open it up (if your confident) and reset your CMOS jumpers (to reset the BIOS to its original settings). You'd need the service manual and a decent computer knowledge and i would seriously recommend asking for a second opinion before trying it, just to make sure i know what I'm talking about. If not, take it to a professional, if it is dead they may not charge you much for looking at it (when my HP Pavilion ze4281 died the people i took it to only charged me AUS$16 which im sure would not be the usual service fee).

Good Luck!

well. after waiting a long time it finally boot up again...even though it works now, i still want to know what is wrong, so incase it's an issue with the notebook i can get an exchange since it's still new

 

It sounds very much like a hardware problem.

Here is what I suggest:
1. Do a RAM test. Use memtest86+ (google)
2. Do a HDD test. Check the website of your HDDmanufacturer for a bootable tool to check the HDD.

This is the easy stuff. There is no easy way to check the motherboard components.

Next time it does this thing:

1. Try an external monitor on the VGA port. Maybe it's the LCD that is acting up (although if there is no HDD activitiy I'm afraid it's the motherboard).

2. You can also try to enter BIOS when it "dies", press F2 just after starting the computer, but if you don't have a screen image there's not much you can do, you can't even verify whether it enters BIOS or not.

3. Unplug computer, take out battery, press power button 3-4 times keeping it pressed for around 10 to 20 seconds each time. That should clear the charge in some/all the capacitors on the motherboard. Then plug it in without the battery, and try to start it up. If it's a transient defect, this might do the trick.
