No Power to the keyboard, but yes power to the mouse

[mstrealy]

My keyboard has no power in any of the usb ports...The mouse has power in all the ports i have tried...I have tried other keyboards with the same result (made sure all keyboards worked with other computers before trying and the did so its not the keyboard itself) Also the mouse has power in all the ports i triedso i dont believe it is the usb ports either. I took the lithium battery out for 20 mins and put it back in and still the same result no power to the keyboard. So i think some how the keyboard got disabled in the bios but i can not get to the bios without the using the keyboard...Has anyone ever had this happen or does anyone know how to get to the bios without using a keyboard...(There in no ps2 port on the computer and no reset button on the motherboard) Thanks

You took the lithium battery out of what, the keyboard or the motherboard?

Is this a wireless keyboard with a USB adapter (transceiver) or a wired keyboard?

Not a wireless keyboard....i took the battery out of the motherboard

When you removed the motherboard battery, did you also disconnect all other power sources (power cable, monitor, and powered speakers)? Then, did you depress the power button to discharge any residual power in the system?

Does the BIOS give any indication that it has been reset?

With the keyboard connected to a known working USB port, just place your hand on the keyboard depressing many keys. While holding down, power the system on and keep holding the keys down. The intent is to cause a keyboard error to force the system to let you access the BIOS. Have you tried this?

If your mouse is working and you can get to your Windows login screen, you can enable the on screen keyboard via the ease of access function. This will at least let you determine if your Windows installation is okay.

You should also be able to look at Device Manager and see if any hardware is indicated as having a problem.
