I have a Sony VGN-CR507E that turns on but screen is black. No beeping or sound when started. Absolutley nothing else happens, power light is on, it didn't show any screens on starting, just the black one and that's it.
Power light is on, battery is charged.
Power pack is lit and appears to be working (it gets warm).
Connected to external monitor, still black screen.
Turned off, removed battery, plugged in, same results.
Computer is still "as came from factory" except a year ago upgraded to "fresh install" Windows 7 from Windows Vista., ran fine after Win7 install.
Tried recovery disks (2 sets) and Windows 7 install disk, nothing happens, black screen only.
Removed RAM and reseated, no change.
Original Hard Drive:
Interface: Serial ATA
Not a complete computer novice, but not a tech either (-:
On a whim, I put the hard drive in another laptop we have, and the of course the other laptop wouldn't start up correctly, but it did let me do some kind of "scan and fix errors" routine on the hard drive, and from what I could tell of the scan results log, the hard drive seems to be OK. There was no message about bad sectors or such, and after it was done it went on to try and start Windows again.
Installed a new hard drive on Sony anyway just to see what would happen, no joy, black screen.
Can't get to BIOS - Tried every combo of keystrokes to try to get to BIOS to check if set to boot from CD, that didn't work either. New hard drive was 320GB, 7200 SATA.
SONY VGN-CR507E - INTEL MOTHERBOARD SYSTEMBOARD A1496672A
I'm thinking this board has everything combined on it, no seperate graphics card(s)? So I may need a new total board ? UGH !
Or is there something else that might be causing this? Help !
