Repost in correct place

What were you doing when it last worked? Did it suddenly shutoff? Or did it reboot/shutdown normally?

Go into your device manager, find the missing hardware, right-click, Properties. Hit the "Details" tab & in the Properties dropbox select "Hardware ID" & do a google search on it. If you want to share it here I can help, but this should help you find the right driver, if it still simply won't install then it might be bad. Just go buy you a usb wireless adapter.

Hi!

Your Compaq V2000 has an Intel Pro Wireless 2200 BG wireles adapter. (doesn't support N, but that's not the point I think)

If your new network configuration is based on WPA/WPA2 encyption, this adapter has some known problems to establish a connection. It works great with WEP, but not so well with WPA.
Sometimes the issue can be solved by installing the latest versions of drivers and software for the wireless adapter.
If it still doesn't work, a known workaround is to disable via device manager all other network adapters in the computer (ethernet adapter), leaving active only the Intel Pro 2200 wireless adapter.


Hope it helped,

Hi,

If you see power lights but nothing appears on the screen, it could be a "POST" (Power-on Self Test) problem or simply LCD problem.

Here are some steps that you can try. One of these may work on your case.

1. Remove the battery and the ac adapter then press the power button for at least 20 seconds to drain electric charges left on the system. (You may need to repeat this step to get it work.)

2. If above step doesn't work, try to plug in an external monitor and see if you get display from the external monitor.

3. If you get display from the external monitor, I'm sure your having problem with the LCD components. In this case, check and replace faulty LCD backlight, LCD cable or LCD inverter. The LCD inverter is often a culprit.

4. Try to reinsert the memory module/s (RAM) of the unit, try using one RAM at a time to see if it works. A faulty RAM will cause the laptop not to POST.

5. If reinserting the RAM doesn't help, most likely your motherboard needs to be replaced.

Hope this helps.

Windows corruption - either a driver is malformed or one of the Wake-up settings from the device or Power settings is wrong. Easiest way is to reinstall: use a generic XP install disk with your key and later get the drivers from the HP site.

i also have a compaq presario f572us that's been having similar problems. when i went onto the hp website i saw that apparently they've been having similar problems with this type of computer as they offer free repairs for 2 years after you bought it. you should probably check if this works for you too

Put another monitor and go to the display settings settings advanced and there u can configure display settings if it wont work so just change the monitor
