I have a compaq desktop computer and when i plug the keyboard in the lights blink but it want work

If the wire to the mouse and keyboard are not usb plugs than make sure they are plugged in correctly and restart your computer.

Try to do a Hard Reset. Disconnect all peripherals connected from the unit (power adapter, monitor, keyboard, etc) then press and hold the power button for around 15 seconds. Plug everything back then power the PC on.

Hope this help. Goodluck!

TO START THE PC HIT F-1
AND NEED A KEYBORD,MUST.TRY TO COLLECTED FROM ANY WHERE.BECAUSE THERE IS NO WAY .

try to plug the keyboard in another computer. If it is analog the lights dont come on the keyboard (caps lock, NUM lock, ect.) it is the tower if the lights do not turn on, it is the keyboard. If your keyboard is USB then try to use it on another computer if it doesnt work it is the keyboard, but if so I would make sure any software the keyboard came with is installed and try it agian.

Pull out the battery and replace it again. Then power it on again. If the problem persists, you will need to have the motherboard, processor and RAM checked by appropriate technical personnel. Any of these could be responsible. 

most probably there is chip falilure, connector wire break, or broken connector pins. if u u not getting any of the lights coming on, then it is certain that ur keyboard is dead.

Hello

Have you tried another keyboard? What troubles me is you said that lights blink when you unplug and replug it in. This jack was never intened to be hot swappable (meaning plug and unplug with power on. I hope the only thing wrong is the keyboard else you'll need a serviceperson to diagnose the motherboard.

I would take the cover off and reseat the memory, video card, and processor. Make sure your fan(s) are working too, and blow any dust out of it if you see a lot of build up.

Dear sir/madam,

please do the following tips to solve:

1. checkout the cable connection between your keyboard panel and port on your computer.

2. checkout the keyboard port, whether its working or damaged (check the keyboard cable connection's pin also)

3.checkout the post settings of computer with keyboard (commonly, keyboard light would blinking on and off at the time of computer boots)

4. if the post will be come properly, then you have to view the keyboard settings in the control panel of operating system.

5. commonly, keyboard issue comes with in the above instructions only. if its not working, you keyboard cable will be damaged or the keyboard have a problem related with in.
here, you can only change the keyboard.
