Question about Acer Aspire 5100 Notebook

1 Answer

Motherboard/usb I have the 5100 aspire, every time I plug something into the usb port, it locks up my laptop. I have tried a restore to the cpu, and uninstalling the usb controllers from device manager. Is there a way to test the mother board if it is ok?

Re: Motherboard/usb

Download the Chipset drivers for your Acer model from their website and install them. This should fix the problem.

My acer aspire 5733Z-4851 donot read usb

That could be a problem with the USB connection on your motherboard. This is not a big issue, if you can you just open up your CPU and locate the USB connection on the motherboard. It is not clear to me whether it is the USB ports from the front panel or it is the USB ports that are on-board (usually found at the back). If it is the USB ports from the back, the one built - in on the board, then the BIOS has to be configured again to enable Plug and Play attributes. If the ports are from front then you need to follow the cable that connects the usb port to the mother board. Disconnect and reconnect. Or check whether it is actually connected to the right port on the motherboard. Usually it is written on the motherboard.

USB ports wont recognize anything I plug in

Are you using XP? If so:
Here is what you can do to refresh the USB ports:
1. Right click MY COMPUTER
3. Select HARDWARE
6. Right click on each USB CONTROLLER and select Uninstall
7. Uninstall all entries
8. Reboot your computer
9. As your computer re-boots it will reinstall all USB connections it detects
THEN, when all other USB items have been configured and connected by the system, you then should try connecting your USB device.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Acer notebook usb not recognized

Sounds like a hardware issue. I would guess that there is a bad connection between the usb's and the motherboard. If you are comfortable dismanteling the laptop and re-soldering the usb's than give that a try, but I would recomend you give it to a pro.
Here is a link that explains the process.

All USB ports not working

Sounds like a shorted out board. If you use a faulty device.. these can EASILY short out the USB controllers on the motherboard.

Alternative is to purchase a "PCMCIA USB expansion card" till you can replace the motherboard.

best wishes.
