have you went onto the BIOS to make sure that the boot options are correct e.g. CD DRIVE 1st priority?

This error usually occurs when the CMOS/BIOS battery is flat.
Replace the BIOS battery and then boot up and go into the BIOS setting to setup the Date & Time etc.

try this...

turn on the laptop,,,
keep pressing F8
a menu screen will appear,, select SAFE MODE using the cursor keys and hit enter,,
once it boots in safe mode click no to use system restore..
follow the onscreen instructions to send it back to a date when it did work,,
it will shut it self down and restart in a propper manner..

if that fails,,

when u turn on the laptop it displays a menu,, it shows to press a certin key to enter system recovery,, press that key,,
follow the onscreen instructions to restor the laptop to factory condition..

Look under "Coin-Cell Battery".

hope that will help you

The Cmos battery is located on the motherboard or mainboard of the PC. It is very difficult in most circumstances to get to them on a laptop.

Post what your problem is and maybe we can be of further help. Explain the problem and the make and model of the laptop.

Not to worry.This is due to some device connected to the system.Disconnect all external device connected and then restart

If you can get to the CMOS battery, there should be a set of jumpers close by that should say Clear CMOS or CMOS reset, or something to that effect. There are usually 3 pins, and the jumper is between 2 of them. Remove the jumper and put back over the pin that was open, and the pin next to it that was jumped before. Leave it for a few seconds, then put back to original position. This should clear the bios, and all you in.

Good luck, and please rate me, OK?

Try this:

Shut down, unplug the AC adaptor, removed the battery, and hold the power button for up to 1 minute to discharge.

Make sure there are no stuck keys.

Restart.

If you feel safe pulling the top plate just above keyboard and removing the keyboard (marker K) on bottom of computer, thie will expose the video cable unplug and reseat it. sometime will fix the problem but the most likely answer will be your LCD is burning out. 5 out of 6 will be LCD but you could be the 1 that just need a reseat.
