HP slimline home computer's keyboard

Have you tried a System Restore/Recovery? Can you boot to Safe Mode with Networking? "is anyway to increase?..Drive"? Why not remove the junk from the drive first, Use freeware CCLEANER at : http://www.filehippo.com/download_ccleaner/

Have you connected any other USB devices that could be draining power? Try to disconnect everything but your mouse and keyboard and see if the problem comes back, if this rectifies the issue get a powered USB hub to connect the rest of your devices.
Also check that the USB bandwidth and power level limits are not being exceeded, I have attached a picture

exact key board driver install then try
what keyboard model?
download load driver for keyboard
update keyboard driver

I have this problem to sometimes. Hold the keyboard connect button with the hub connect button at the same time. If this doesn't work then restart the computer. If this does not work reinstall the software.

Was the keyboard working before you cleaned it? Did you removed the keyboard connector, might just be loose connection. Check the connection again and see if it works. Keyboards faults normally starts with one or few keys not responding properly, and if the entire keyboard doesn't seem to respond then it's most likely faulty.

If this doesn't fix then you need to buy yourself a new keyboard.

hope this helps.

It is possible that the bios is set to not support legacy usb devices. if this is the case you may have to get a ps2 style keyboard to go in and check it. Otherwise your keyboard could be bad. check it on another computer.
Or your USB drivers could be no good or faulty. reinstall motherboard drivers from the manufacturer.

Buggy Motherboard... could be the BIOS could use an upgrade, Bad Battery on MB, or MB could just be bad. Data on you drive is good and recoverable. New PC ? Buy.com a Referb Box is a good choice if you are on a budget. A Turion Processor is not worth the expense to fix in my opinion. If you can do it youself,for fun, replace Motherboard, HD and CPU and re-use the rest. Buying a new one, even a real cheep one is a less frustrating solution.

I told the computer not to go to sleep when I leave it unattended. It worked!
Thanks for your help, Basti!

i dont think so it may be compatible just send to total details of your system and keyboard and adapter

Unplug the AC power, remove the battery, wait a full minute and then reinstall AC and battery. See, if you now power up. Most power up problems are related to AC power, DC input jack, motherboard, memory or processor. A lot depends on your comfort level and expertise in how far you should go in self diagnosis and repair. Good Luck.
