20 Most Recent Compaq Presario V400 14" CRT Monitor Questions & Answers

Did you mean you want to connect your computer to a TV?If you did and connected it but nothing happened then you may have to select the correct input on the TV remote. It used to be called AV but some of them have a little picture of a screen with and arrow pointing in to it from the left.You just switch your TV on, switch your computer on, then press the button on the remote a few times until you get the PC input picture. You may also have to hold the Fn key on the computer and press one of the keys with a Monitor / TV screen symbol on it. It maybe one of the Function keys or one of the number keys at the top of the keyboard.

take the moniter to a known good pc and see if it work if moniter works correctly it is your video card if not you need a new moniter

This happens when your screen resolution is set to something higher than what your monitor can display. For example, if your monitor supports resolutions of up to 1024x768 and your video card allows you to crank it up to 1600x1200, doing so will give you an error. Another reason you might get the error is if the refresh rate you selected a certain resolution is higher than what your monitor supports. The monitor can't "sync" with the video card, so it just gives you that "Out of Range" error. If you are sure you have your resolution set at a reasonable amount, make sure that your monitor is plugged in all the way. Actually, if you're like me, that might be the first thing to check. =)

If you are using Windows, hold down the F8 key while the computer is starting up and choose "Safe Mode" from the list of options that appears on the screen. This should force the display to be a low enough resolution so that it will work.

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...

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
