CFFL lamps dead, or its inverter, 99% on CCFL tubes. bad. all screens this old do that, they have short life... why not upgrade , go to used PC store get any PC there, 2010 or newer, that has no CCFL (has LED back lamps) and a future. best is one with W7 COA sticker on bottom. XP aND vista ARE DEAD OS now, not safe at all on the internet nor does PnP work now, at MS.com why even mess with old tubby CCFL laptops? carbon14 dated at 1999 , (as old as) its 18 years old. most are in the land fill, 99% or more. or shipped to N.korea for CAUSE.

There are a few things that come to mind:

1. Turn off the laptop and leave it off for 5 minutes- then restart it (with the external monitor unplugged). Check to see if you have your video back.
2. Unplug the monitor, then hit the hotkeys again to switch back and forth between inputs- does the video show up?
3. There could be a loose wiring/connection issue between screen and the rest of the laptop. Sometimes fiddling around with opening and closing the lid will work. Otherwise, you may need to open the laptop to check the connection between the two (not recommended if you are not good with fiddling around inside computers), or taking it to a tech who can do it for you.

Hope these answers help.

if the compaq logo is also not appering the the issue is with the RAM and the slot is to be cleaned and reinserted the issue will be resolved.

In case somebody has the same problem. Result of my investigation: * If everything is ok then the Presario CQ61 boots without battery. * HP support recommends to do a hard reset i.e. remove power supply, remove battery, press power button to discharge everything internally, connect power, press power button In my case the problem was solved by changing the AC Adapter (Power supply). Note: The led besides the power connector is not reliable. It is on with the working and faulty adapter. Note: The voltage level at the battery pins is not reliable. I had same values.

old PC,, Cq series. cq62-nnnnn you left off the nnnnnn cq62-100, 200 ,300 what? running mS windows 8 HP does not support W8 on this PC so that means you are on your own steam...

check o see if your sound driver is compatible with new software operating system.

Find your model number near the serial number. With that number go to the following link and enter it. This link is for HP's support website. You can find everything about your PC, replacement parts, Drivers, Manual. HP Troubleshooting

Please ask a question so we may help you.

Oh dear you have broken this and will need to send it off to be fixed.

Won't load in safe mode?? What's your operating system? Has the hard drive been formatted?

1. Turn off your computer. 2. Press the power button to turn your computer on. 3. Hit F11 a few times quickly, while the launch screen is still up. This will launch the Recovery Manager. (If you see the Windows 7 boot logo, you've missed your chance and need to restart your computer and try again from step 2.) 4. On the left side it will say "I need help immediately". Underneath that there will be an option that says "System Recovery". Click on that. 5. There will be an option to either back up your files before restoring, or to recover without backing up your files. In my case, I'm recovering without backing up my files. 6. It will tell you to make sure all devices are disconnected from your computer. Make sure they are, and then click "OK". 7. There will be a "Welcome to the Recovery Manager" screen. Click "Next". 8. It will begin to reformat your partition and to reinstall the Windows 7 setup files. Once it's done doing that, click "Next". You'll be brought to a page saying "Recovery is Complete". After that all you need to do is reboot, and it will bring you through the wizard to set up Windows 7, just like on a new computer! Good luck :)

THIS IS NOT A PROBLEM THAT NEEDS to be asked on here as there are so many stolen laptops about ,ull need to go to a repair shop with proof of purchase or something that is on your system that only yourself could identify , to regain access to your laptop..

Try to reinstall windows formatting your Hard Drive... It seems to be an windows crash, or some software.

Drive is formatted with wrong file system. The files you're trying to copy are too big
