My acer aspire 5100 keyboard,usb

A temporay solution is to use a pcmia card with usb port slots. That way you can connect a usb keyboard, usb mouse or any other peripheral device thru this slot. It has worked for me for 1 month so far. It is the most inexpensive way to temporarily fix this aspire 5100 manufacturer defect. I believe that this model easily overheats and affects the motherboard in areas that control dvd, usbs, keyboard and mouse. I am contemplating a suit against Acer for this 'lemon' of a product. There has been no recall nor support from Acer to fix this problem and they continue selling this and other defective products. Feel free to email me at gitmodotcom@aol.com from comments or questions. Ray=)

My Aspire 5100 has the same problem. There is also a small dent under the Microsoft button as though something melted underneath. I believe that my fix will require a new mother board.

hi there pntbrshro172

I did what you have in your post. It worked for me. The mouse and keyboard worked perfectly fine but when i restarted my acer, it had the same problem. i can't put my laptop in my freezer everytime i'll be using it.LOL..you have any other solutions?thanks a lot for your help..i really appreciate it..

I had a similar problem with the Ace Aspire 5100. So, I got a P2A 1080 PPA 1080 4 Port USB 2.0 PCMCIA Card bought in JR and Windows Vista recognized it. So, I was able to connect my wireless mouse and keyboard using an usb connection.

Good luck.

O.K If you follow these instructions to the letter ,I can help you get your system up and running again.Acer motherboards have the CMOS battery hardwired in its frame work and cant be changed This is where your problem is.Unlike most other computer brands you can change out the CMOS battery like a watch battery.
First Dont panic.
Now go to a computer supply store and get a de-magnatised computer screw driver set and cpu thermal paste ( artic silver).
Remove battery
Remove all srews from the back of the laptop
open and remove back cover.
Remove the Hard drive,and ram stick
Flip laptap bak upright and remove title bar strip or power bar strip (its the plastic strip above the keyboard) its only snapped in so be gentle .Remove the screws that are visible here.
Remover keyboard and unplug the circuit stip to both the keyboard and touchpad mouse.
Remove the power plug leading to your screen.
Remove the entire keyboard face plate with a few more screws.
Flip laptop back over and remove the fan the cpu heat sink and cpu.
Follow the wires leading from your screen to the clipset.unplug the black and white wires then remove the chipset.Pull the LCD creen wire through the board and remove the screen from you laptop.
Now all that should be left is your motherboard and dvd rom drive.
At this point your going to empty the information being held by your corrupted CMOS battery by FREEZIN IT!!! YES FREEZIN IT. Put mother board in your freezer for no shorter then 10 hours ,taken it out once ever 2 hour for 10 mins to warm then back to the freezer again. This process will clear the CMOS battery.
Now its time to put all back together.
Follow your step backwards until you reach the point of installing your CPU.
Take a cue tip with some rubbing alcohol and remove the old thermal paste from the cpu and heat sink. Now add a tick tak size amount to you CPU and reseat it in its housing (notice the small arrow on the cpu and housing indicting the direction for the cpu to set.) tighten down retainting screws. and install the heat sink.
Finish the process backwards until your laptop is back together.
Turn your pc on and you should be good to go.
I further recommend backing up all data and reformating your drive.Also change any settings in you BIOS to its default levels.
I rate this process a difficulty of 5 out of 10

I've tried removing the battery, and some other measures to no avail. What did worked for me is: after the the acer screen appears, I held the function key down [FN] while pressing the [F6] key off and on. If your screen flickers from blank to where you can see the screen, then this should work. Turn the computer off, then back on when the acer screen is displayed, press the [FN] key and [F6] and keep the blank screen. That is it, the computer should boot up and the your regular screen should be visible with mouse and keyboard function.

If you can get the screen to flicker with [FN] and [F6] your keyboard and mouse is still working.

Ps. I tried [FN] and [F7] first, then [FN] and [F6].

I have a Acer Aspire 5100 with no touchpad, keyboard and mouse. I've been working on this problem for a few days and tried all of the above except the freezer fix. I managed to reset the CMOS by shorting the J2 jumper in the near the SODIMM slots. Still didn't fix the 3 dead devices. I had encountered this problem after installing XP and while updating SP3 after a reboot killed all 3 devices. I'm thinking that the acer boot CD may do the trick. I also found you could boot from the CD by pulling the HD out. This is becoming a mission. If I don't find a boot CD soon I'll be getting a PCMCIA card.

hi,

I had the same problem. I fixed it and I hope it works for you. Remove the hard drive, then I put in the acer windows reinstall cd and booted from it. It loaded windows and as I got to the install windows screen, I picked the repair windows option. at this point I realized the keyboard was working. I shut down the laptop using the power button and reinstalled the hard drive. Notice I did not continue reinstalling windows. I booted up and everything worked. I couldn't beleive it. I thought for sure it was a motherboard problem. Hope this works for you.

I have precisely the same problem with my 5100-3123. I took it apart - a pretty involved task - and inspected my keyboard and mouse connection cables. Nothing was wrong so I plugged them back in again.

The good news for me was this got the keyboard working again, so there was some hope.

The Bad news, mouse was still offline and USB ports weren't working either. Plugging anything into the USB ports froze the system. I checked my device manager, it doesn't show any conflicts with the USB devices. It also did not show any mouse drivers or such present.

At this point, it's hard for me to tell if I can fix this with another mouse pad, or if the problem goes much further.

However, I think that PCMCIA USB card suggestion was top notch. Using one of those, I can grab a mouse and work around the problems (in theory).

So give your device cables another go... maybe they just became loose, or jolted out of poisition from dropping the laptop.

G'luck
