Re: cannot start ,sometimes happen sometimes ok

The first thing you want tod o is to determine the problem. Itt's probably the backlight on you screen.

To check this hold you lap top up to a very bright light, but don't allow any glare onto he screen, turn it on, You should see the shadow images of the stuff you computer normally does. If this happens( I'm 90% sure it will) proceed to next step.

Try pressing the brightness adjusting feature of those lamps, this is usually done with some combination of the Fn key and F7 or F8 (you should see a blue light bulb symbol in the corner of one of these keys.) if this doesn't work proceed to next step.

go buy CCFL tubes (there little diode like lights) If you are unsure about taking you laptop apart don't risk this, follow instructions in link to change back lights.

If this stuff doesn't work, aggghhh who am I kidding. This WILL work.

I assume no responsibility for you messing up your or any one elses laptop while trying to follow these instructions.

A bit vague? Unplug, remove battery, leave battery out, plug in , push the on/off button. Describe what happens, fan spins? LED's blink? HDD spins up? Sound? Any thing on the screen?

3 Press and hold down the power button for 30 seconds.
4 Conncet the charger (don't connect the battery yet) and try to start by pressing the power button.

Also listen carefully for any beep sounds if you hear beep sound then the rams could be defective otherwise the mother board seems to be defective.

Acer Aspire 3050 will not boot - LEDs flashing 8 times

My Gateway did that it was due to the power adaptor being loose on the motherboard. Push the cord in and rotate it and continuously push the power button if it starts that is your problrm. You can temporarily fix it with tape once you discover where the cord wants to be or you can use a clamp.

Compaq presario 2500 notebook won't boot

This sounds like a weird solution, but it worked for me. I recently bought a used Presario 2500, it worked when the guy showed it to me, when I got home it didn't work two days later. I tried several tips from the web, finally I started pushing several buttons randomly. I pushed the Email (Envelope) button, and the computer powered on suddenly. Now, the Envelope button is the only button that will power the computer on. When the computer is on, that button will also bring up Outlook, but when the computer is off, that button turns it on. Let me know if this fixes it for you.

Not uncommon... the power switching chip that regulates standby and other power regulation to the board must be faulty or fried. Must replace motherboard.. Try removing battery.. sometimes batteries will short or try to draw too much power and put the chip on the fritz..

best wishes.
