View Full Version : Motherboard Rear Panel not working

07-08-2007, 03:04 PM
okay im trying to fix a friends Acer Power F1 desktop (p4 2.4 etc) and it boots fine and goes to the windows user selection screen but nothing on the rear motherboard ports work.... this includes usb ports, ps2 mouse and keyboard ports etc. so pretty much i have a computer that works but i just cant use it becaue i have no input. the keyboard lights dont come on during post and the keyboard does not work during post either.

is the motherboard fried and do i need a new one or can i fix it? maybe a reflash with the bios (not sure how id do this if i have no keyboard support tho)

anyone got some advice??

Well do you get an error on POST which says " Keyboard error, Press F1 to continue" or something similar?

If not then it may not be the rear panel. Have you tried a different keyboard/mouse?

What kind of motherboard is it?

there is no error about the keyboard, as i said it boots like normal the windows user screen.

i have tried different usb and ps2 devices and none work.

i cant see any label or brand on the board but the cpu fan is labelled Foxxconn so maybe its a Foxxconn board.

Replace it, it sounds like its 1/2 dead.

Check in your BIOS that it is set to halt on keyboard errors.
Some BIOS's can be configured to not stop on keyboard failure, check this.
Also check in the BIOS to see if the USB devices etc. have been disabled. I doubt this very much but it is a possibility.

i would have done that but i cant even get into the bios because there is no keyboard even during post. i did mention that in my first post.

oh yes. n00b to me:rolleyes: lol
ok, you could reset your BIOS and see if any thing happens.

You could pull the cmos battery out, but then how is he going to reconfigure the BIOS??

The BIOS would be back at factory settings - so if he had somehow disabled that usb ports, these would be re-enabled and problem solved. Though i doubt very much if this is the problem. Just another option.

Well u need SOMETHING like a keyboard to actually move from menu to menu.

You don't need a keyboard to reset the BIOS.
Once the BIOS is reset, why would you need to go into the BIOS?
If the usb ports had been disabled, they would now be re-enabled and they would be fine.
Read my previous post more carefully please ;)

i understand what he means, if i was to reset the biops then the keyboard might start working and therefore i would be able to reconfigure it. ill try it.

Glad to hear you got the point :cool:
Not too sure why you would want to reconfigure the BIOS - are you overclocking or something?
As already mentioned i doubt very much if this is the problem, but everything is worth a try

Well, HOPEFULLY resetting the BIOS fixes it.

Otherwise, that wont be only thing that wont be working.

Just my 2 cents worth:2cents: if you are able to locate a Linux Live CD like Knoppix and boot from that it will detect any working ports, if the Keyboard / Mouse are not detected by the Live CD then theres a good chance the Boards faulty. Good luck

True, while on similar topic, you could also try Windows Ultimate Boot CD.

Its stuffed. Throw it out.

07-08-2007, 06:16 PM
Lol, most likely.
Sucks when mobo's die on you. I had to replace mine earlier this year - $300 later....:annoyed:

07-08-2007, 06:34 PM

im not reconfiguring rather i meant just setup the way i wanted. thanks
