Hello,
Try this quick fix :
What I suspect here is that you tried a bad CD or
DVD disk inside your drive, in that case, get a very
good lens cleaner to clean your drive first.
If that doesn't work,
Get a screw driver and trace the screw holding the
CD/DVD Drive to your system at the back of your
laptop, then unscrew it and remove your drive. If you
cant do this by yourself, just try and get a good
technician to do it for you. Then clean the interface
connecting the drive to your laptop.
After this, power up your system normally without the
drive connected.
Then shut down properly, and reconnect the drive,
making sure that its firmly connected.
Then power on again and check it in the system
BIOS if its now detected, then save and exit, then
boot your system properly again.
If it doesn't work after this, then I'm afraid you might
have to get another drive.
Hope this helps you out.
Goodluck!

plz try with a new drive

I believe the other device listed is your card reader

Press fn then F9 for locking and unlocking touchpads.

Also try to power cycle your battery.Unplug the power adapter, press and hold down power button for 30 secs. When it is already powered off, take the battery out, put the battery back. Then power the laptop on. This should also resolved the issue.

Thank you!

Mark, there is a good chance that the power supply is not working correctly.
If you can (or have someone) test the output, it either is not providing the power or the connector(s) is/are bad.
The people at your local Radio Shack may be willing to do the test for you. (since most are Compaq dealers)

if ur getting a constant beeping sound then the problem can be with the ram cards so u need to ope the pc and check with the ram cards first of all

change the resolution

Probably the plug is damaged or the adapter is out ..cause in any other cases it would worked with the adapter in ..even if thebattery is out ..
if there is no light on the stand by ..or other lights control ..than you have to see if the adapter is still functional to eliminate this issue ..after that try to charge the battery in another one and see if it still works on batteries at leas...If all that done ..and it still not getting power at all...Not necessary start ..but see lights or such ..than it is not a power issue but the motherboard has a damages either on the powering line ..or the CPU itself..

This could be due to corrupt wireless drivers or corrupt BIOS settings. To isolate this, uninstall and reinstall the wireless drivers on the notebook. If issue persists, then update BIOS and check for the issue. Incase, if the issue is unresolved, then check if the Wireless network adapter is detected in Device Manager or not.

If it is not detected, then remove and reseat the wireless network card on the notebook. Incase, if the issue is unresolved, it clearly states that the wireless card on the notebook has gone bad. At this point, I would suggest you to take the notebook to any nearest Authorized Service Center in your location.

Lots of possibilities here.

• power
• memory
• mother board
  

Verify that you have enough power. Do you see power when connected to the laptop before you boot?

Try removing the memory and putting it back. Does it boot. Try putting in only one stick of memory. If that does not work, try the other stick.

Try removing the battery, and booting only on the power supply. If the machine boots without the battery, you have a battery problem.

Hopefully, one of these will help you understand your problem.
