Solve : Laptop won't start?

1.	Solve : Laptop won't start?
Answer» Hi, I have a Sony Vaio PCG-7D1M laptop. When I switch it on, it displays the Sony Vaio logo for about 30 seconds, then the screen goes blank and nothing else happens. I can't press and keys to get it to go into the bios. It doesn't shut itself down, it just remains powered on with a blank screen. If there is a cd in the drive, it will spin that, and all the other lights on come (power led, wifi led ETC...). The power light stays on green, but the battery light is orange. If I plug in the power cable, the battery light blinks a few times, then goes back to solid orange. Any ideas what is WRONG??? Nick nickc,Not really very knowledgeable about laptops.However have you tried removing the battery and running it just off the A/C power supply? If so what were the results? truenorthHi, Yes, I tried removing the battery. When I plugged in the power cable and turned it on, it was completely dead. I also noticed that the cable was a little loose in the socket. This leads me to think it is a problem with the power socket (or maybe the power adapter). I guess that the battery has run down to a point where it will allow the laptop to be powered on, but not to be booted upQuote allow the laptop to be powered on, but not to be booted up The laptop still powers on?

If you have access to a computer shop there are many very inexpensive multi voltage after market adapters/chargers available. I would 1st take the laptop to one that will let you try one of their adapter units in the store to see if it makes any difference.

If you can you could try making a temporary bridge with 2 small wires between the adapter plug end and if you can CONNECT them to the laptop power connecting point.

Hi,

I have a Sony Vaio PCG-7D1M laptop. When I switch it on, it displays the Sony Vaio logo for about 30 seconds, then the screen goes blank and nothing else happens. I can't press and keys to get it to go into the bios. It doesn't shut itself down, it just remains powered on with a blank screen.

If there is a cd in the drive, it will spin that, and all the other lights on come (power led, wifi led ETC...). The power light stays on green, but the battery light is orange. If I plug in the power cable, the battery light blinks a few times, then goes back to solid orange.

Any ideas what is WRONG???

The laptop still powers on?
