keyboard fai to work

Hi folks,

Motherboard Asus A8NVM

keyboard fails to work

This happened after an incident of power interrupt. The power supply was accidentally interrupted while the PC booted CRrom. It just started to boot. From that time onwards on starting PC, pressing [Del] did not start BIOS. The PC booted straight to HD, boot sequency set, floppy/CDrom/Hd. After booting up the OS (tried FC5_64 and WindowsXP as well) keyboard failed to work. It did not type on Doc., such as Editor, Webbrowser, etc. Changing another keyboard did not help. Pleasd advise how to fix this problem. TIA

could you specify type and make & model eg usb Joe bloggs eazytype

2) the del key did not start bios I hope means you can no longer get into bios as bios always starts if the hard drive does.

3) if you have a cordless/battery keyboard maybe its just the battery?

however, b4 booting turn over your keyboard and give it a number of clear any food (?) or dust....maybe the grit is interfering with the del key?

4) if still no good try pulling off the del key and having a look at the design pls.

5) finally press hard and quickly your del key?

assuming no luck with question 1.

Hi aus9,

Tks for your advice.

Problem already solved.

- removed the CMOS battery
- allowed PC standing for about 10 min.
- replugged the battery and turned on PC
- booted to BIOS default

Because the power supply interrupted suddenly which caused confusion to CMOS. Unplugging the battery cleared the residue memory.

Switch another keyboard in and hope the keyboard is just burnt out. Since you cannot get into bios it is a hardware problem and not a OS problem. There is a high probability that some damage was done to the motherboard. On some motherboards there is a soldier on fuse that can blow. In my expience once this fuse blows it is a reoccuring problem. Good UPSs will prevent this kind of problem and buy you time to safely shudown the machine. Assuming you are not running a USB keyboard you may be able to add one by just plugging it in and booting. This will not give you acces to the bios.


You got sooo lucky.
