Having problems with your Sony VAIO VGN-NR285E/T Laptop ?

Unit powers on, LCD flashes for 2 seconds, but HD does not boot


Answers :

Either the BIOS has lost the hard disk configuration or the hard disk controller has failed or the hard disk is faulty.
\015\012Go into the BIOS configuration and see if it detects the hard disk. If not
\015\012then re-seat the hard drive and then boot up the Sony laptop.
\015\012If it still does not boot up or detects the hard disk, then to determine if the hard disk is faulty, remove the hard disk and connect it to an USB hard drive adapter and then plug it into a working computer's USB port. This computer should see this as an external hard drive and if you can open the folders and files then the hard drive is OK and the fault is probably a faulty hard disk controller. This is a motherboard problem.
\015\012If you cannot detect the hard drive then the hard drive is faulty. To get the laptop working again, replace the hard drive, install Windows, install the Sony's device drivers and your programs.
