Please help.. I was listening to a music from cd on my laptop. I used the laptop battery as a power and not plugged into electricity. Then i heard the song became unstable and then it went off, run out of battery. At that time i just put the laptop aside, not directly recharge the battery. The next day when i turned it on with the power connected to the electricity, it went black screen. I've tried to use the F1 or F2 but it showed only blinking dash. Can i recover the hard disk? How to do it? I went to the computer store but he said the hard disk cant be saved. I didnt trust the guy because he just turned on the laptop and saw the blinking dash, not doing anything else, directly made a judgement like that. Anyone can give solution? i havent made any backup, that's why i need it. Thanks in advance..
The contents of the disk can almost certainly be recovered, any data on there should be safe. From what you've said in your OP it seems more likely to be a hardware issue than a hard disk failure.
Building on Jollyjohn's reply; you'll want to remove the disk - if you don't feel 100% comfortable with this I'd recommending asking someone to help you. Once removed put the disk in a disk caddy. You can then plug the disk into another PC and access it like you would a USB pen drive.
However, if you want to find out what is causing the problem, you'll want to start by doing what Fruit Bat suggested - use your Windows Vista DVD (if you have one) and try booting from the disk. This might involve entering the BIOS and selecting the DVD drive as the primary boot device (although this will usually be set by default, unless you've changed it yourself).
If your laptop does manage to boot from the disk, you'll be given the option to 'Repair' Windows without losing your personal data.
