Having problems with your HP Pavilion a1540n PC Desktop ?

Boot hangs, even with a bootable CD. Problem started with keyboard and mouse failure and error messages re those. Keyboard and mouse still don't work, so I can't hit F8 to enter Safe Mode.


Answers :

Start by trying another keyboard, if you are using a old styled keyboard with a round connector, try one of those usb keyboards and see if it helps or find another round styled connector keyboard that goes into the violet keyboard connector on the back. If your machine doesn't work with another set of keys, not on either usb or the ps2(round connector) Let me know if you are in warranty? If you are outside of warranty, you could unplug all the cables, open the side cover of the computer and find the flat 3volt battery inside. Remove the 3volt battery for a few hours and place it back in, replug the machine to power etc. Try starting up again try both usb and the Ps2 keyboards and see if it works. If it still doesn't work your computer most likely has a faulty motherboard, and it might have to be replaced, I would recommend that you get someone to look at the computer locally or to come over, or you can replace the mainboard. Take the old one to a dealer /reseller - that sells computer parts like motherboards and related and ask to get either the same mainboard or another one with the same cpu socket, same memory, etc so it fits to your other parts. After replacing the mainboard if the issue still remains its time to get a professional to look at the machine.
