Specs: Windows 7, 6gb
Few days ago my laptop with ST9500325AS sata HDD (500gb) was not started at all. when i took to a local computer shop, they said that the HD was damaged. So i bring a new HDD of WD5000LPVT 500gb.It worked fine for me around two weeks. One night i played tom clancy HAWK game for few hours. then i shut down the laptop normally and went to sleep. by the next morning when i turned on the laptop was not screen display even the system logo.the power light and battery light were blinking as normal but the HDD was not. So to check my laptop i assembled my laptop with older Seagate (ST9500325AS sata HDD (500gb) hd. the laptop started fine. Then i took the WD hdd to the shop from where i brought again to replace it as it is still in warranty period.They checked it with a external adapter used in external hd. the WD hd worked fine in that case. all files can be opened when it connected via usb operated adapter.they didnot replace it to me. but when i assembled it on my laptop inside, it would not worked. i tried it several times. but no display and only black screen. i canot find where the problem it with my laptop or my WD HDD. my laptop config are given below

Just because a hard drive can be read okay when connected to a USB adapter, it doesn't necessarily mean it will boot in to Windows okay when you put it back in your computer.

The Windows installation or Windows startup configuration on the drive could be messed up. If it's just the startup configuration that's messed up, you can usually fix that by booting from a Windows 7 System Repair Disc and choosing "Startup Repair".

You are supposed to make this repair disc with the utility that's built in to Windows when your laptop was working okay. If you didn't make one, ask a friend who has Windows 7 to make one for you.

✔ Best Answer
So the laptop display is not showing anything, even the power-on self-test? What happens if you remove the hard drive and turn on the laptop? If the laptop is showing the power-on self-test, I think, perhaps there's a problem with the hard drive controller on the motherboard.

Have You tried to connect the laptop to the external monitor?
What happens if You remove the battery and running it with the power adapter?
Or, try pressing the power button for 30 secs after removing the battery and unplugging the power adapter, and turn it on again.
