    It could be the lid sensor. Try rubbing a magnet to the left of the keyboard near the caps/numlock lights (above the DVD drive).

    If the GPU is dead it will turn the light on for a few sec but you only get black screen. It might be the GPU.

    I would try the following steps...

    1. RE-FLASH THE BIOS:


    • Download the current BIOS for that model
    • Prepare a thumbdrive with the BIOS file and insert it in a USB 2.0 port
    • Try to access the BIOS setup (F2) or the EZ Flash utility (F4) on start-up
    • If the previous efforts don't open the BIOS, try them again, after a CMOS reset
    • If you can get into the BIOS or EZFlash, update or re-flash the BIOS

    So if you can establish a successful BIOS flash, the next step is making sure that there's an available boot option.

    2. BOOT FROM A KNOWN-WORKING BOOT SOURCE:


    • With a valid BIOS, you should be able to access the boot menu (ESC) or the BIOS setup (F2) to select boot devices
    • Use a bootable CD like a Windows installer or repair disk, to try and boot from the optical drive
    • If the optical drive doesn't work, try making a bootable USB thumbdrive and boot from that

    Bottom Line: If you cannot access the BIOS on this computer, it is indeed non-functional as described by your eBay seller. No computer can be made functional so long as it has a corrupted or damaged BIOS.

    hey , i cant see anything on the screen , how can i flash?
    can you give me the steps to acces flash drive blindly . by counting the no of times the key should be pressed.

    If you don't think this computer has any video functionality, this is all a moot point. You can't use it unless you get that fixed.


    But I saw nothing in your previous posts that suggested you think that is the specific problem. Rather, you have described a computer that doesn't post or boot up. If you believe that you're not seeing anything on-screen because there is a BIOS and/or boot device problem, rather than just failed video, I was suggesting ways that you can at least try to address those issues.

    So again, my initial point was that you need to be able to access the BIOS, and to re-flash it if you can get in there. Refer back to my previous post for more detail, but essentially:

    • To access BIOS setup, press F2 immediately & repeatedly after pressing the power button.
    • To directly access the EZ Flash utility, press F4 immediately & repeatedly after pressing the power button.

    If you cannot do this, either because the video has failed or because the BIOS is corrupted, the computer needs to be serviced if you want to restore it to a working condition.

    You could try attaching an external monitor or LCD via HDMI or VGA ports. If that fails to display any video, you're still stuck with possible failed GPU or corrupt BIOS. BUT if it does display video, you know the problem is your laptop display or LCD video cable or connection.
