Even after replacing the batteries, nothing appears on the screen

It would be helpful if we knew the Make, Model of Laptop and the OS you are using? Try a hard restart , remove ALL media, DVD, CD, USB, etc., unplug , remove battery, leave battery out, plug in , reboot. Describe what happens, Fan spins? LED's blink? HDD spins up? Sound? Anything on screen? Have you tried a System Restore/Recovery? You can start by removing the HDD and testing it, if you done have a USB to sata/ide adapter take it to a Qualified Computer Tech.

take out the batteries; remove cartridge. press hold power button for 30 seconds. place batts back in and try to turn toy on

If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

You may need to replace the batteries.

I had the same problem. I remove all four batteries and the battery backup that is underneath the little phillips screw in the battery compartment. I immediately replaced it and the other batteries and everything worked. FYI, others have called for keeping the batteries out for 8 hours.

sounds like the mother board is failed..try one more thing..remove battery, run on power supply only, and see if that helps..otherwise, it's motherboard replacement time.

try hooking up an external video source. Check to see if the computer is actually booting up. if the computer boots up, then the LCD invertor or Backlight of the screen is bad, need to be replaced.

If the computer does not boot up after hooking up an external video source, then most likely your motherboard is bad!


need to be replaced.

replace the cr123 batteries. If one of them is down on voltage you will experience exactly the symptoms you describe.

Press and hold the volume up + key and the select button to perform a "hard reset" Best of Luck.

it could be a bad battery which would have functioned for a while then went bad. if you take it to a watch store they can try a new battery if it works buy it if it doesn't then don't. even some walmarts in the jewelry dept have the batterys
