USB Ports Not working

I have a Gateway Laptop, 4540 GZ and none of the USB Ports are working. I have restored the system and all the drivers look fine. I think it may be the motherboard, other thoughts out there? Anyone know step by step instructions to replace the motherboard?

Re: USB Ports Not working

You need to go to device manager and look in the list at the bottom for the usb root hub and see if there are any red crosses or exclamation marks, red crosses mean device dissabled, exclamation means not recognised and no suitable driver. click on the link below and select motherboard downloads for the usb drivers If you do find that the motherboard is faulty, then you can purchase a PCMCIA USB 2.0 card, as long as your notebook has the PCMCIA slot, as i am sure it has.

My NV55c laptop usb ports on the right side suddenly have stopped working.

Motherboard issue.assuming all the drivers are properly installed. Not uncommon. Use the remainder and if necessary get an adapter to increase the number of ports you have.

Usb ports on laptop won't work

You need to get into your "Device Drivers" located in your "system" to see whether they are shut off. Go to your control panel to find your "System" files.

You may need to click on each one and update the drivers.

I hope this helps.

USB Port not working

If you are running Windows XP or Vista, here is a "magic fix" that seems to work. (I have NO idea why it works, but it has on many occasions restored the USB ports on three different computers.
Turn off the laptop. Remove the power cord AND the battery. Press the start button and hold for 5 seconds. Replace the battery back into the laptop, and reconnect the power cord if desired, and turn it back on. See if the USB ports work now. Post or comment back with the results.

does your usb mem stick have any light indicators? if yes , whenever you put you usb stick, does it light? if it lights are USB ports is still ok,  You just have to reformat or partition you USB stick.
(you can also try other devices like usb mouse or any usb devices that lights up when you connect it)

if there are no lights if you plug, or no indication that a power goes to your stick, its possible that your usb your are busted. if this is the case, if your laptop has a PCMIA slot, you can find a pcmia USB card, if you dont have. your only option is replace the  motherboard.

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.
