Acer Aspire 5103 laptop dead usb ports problem

Hi there, during the last 2 weeks, all my usb ports on the laptop are not working. first it was just the 2 at the back of the laptop, then the 3rd one went a couple of days ago, i am at my wits end trying to sort this out, i have tried to find a solution online, nothing concrete as yet. i have had the laptop for 14 months and it is running windows vista. i have checked the usb controllers and hubs on the device manager, they're shown to be all working properly. i have also tried to uninstall and install the drivers but nothing! please help!

thanks

Sanjay

    This may be a silly question but are you trying to use more than one device. If the device manager is showing all usb port/drivers it may be a power issue.

    Have you allowed the Vista SP1 to install lately? To know if you have Vista SP press the following keys at the exact same time. Windows Key + Pause. The notation is in the upper right portion of the first page displayed.

    If you see inside Devise Manger, that your USB Hubs are not only working okay, but have 500 mA of power, there should be no problem. Have you attached a device to a socket and then checked the USB hut in DM and see if the device is listed and shows how much mA are being assigned? Would you do this with a pen drive or Memory Card reader/holder and then post these mAs drawn to me here as a comment in the box below this text?

    Thanks,

Sounds like motherboard problems or its having a hardware conflict.Check your bios settings and set the default configuration.If that does'nt help i would be looking towards the motherboard.

Acer web cam not working last 2 weeks,model of lap top is:aspire 5630


Check your device manager for the imaging device ( webcam )
If not found, try booting into safe mode and give a look again in device manager.
If you have any usb devices connected disconnect them
If all of this do not work, you may have disconnected the webcam or could be bad.

Hope this helps

Acer Aspire 5100-3357 lost function of keyboard, touchpad and USB


hello, this has been one of the most reported problem with the 5100 model. i have 2 of them, and they have done the same thing! one i had 2 find and install a new mainboard-400 bucks! not very cost friendly. i did post a solution more than a year ago, but it is a work around that let me use the acer with the dead keyboard,touchpad,usb- you must buy a pcmcia usb card, it goes in the slot on the left side of the acer 5100. then a usb mouse and keyboard will work. (you can get this cardbus adapter cheap, as 400 bucks is 2 much. these pcmcia cardbus card come with 2 or 4 ports. this will let you use the pc, it has been a great solution for me and a lot of others, been in use over a year like this. acer is no help, unless you wish 2 spend a large amount of $. the one with the new board lasted about 8 months before the usb port stopped working for the second time, i then got a second cardbus usb card and have usb again. sorry for your problem.. good luck! do as i say and the acer will work again.( a problem model) just search for pcmcia usb cardbus you will find many 2 choose from- i picked the ones with the NEC chipset, as these are reliable! be well!

HP Printer Usb port in my Acer Laptop , shortcircuits my house


hello

Try using external USB HUB (POWERED) Adapter. It might fix this issue.
Use an other USB cable and see.
If the problem still exist do not plug in the printer again, you may damage your USB port or even burn your laptop motherboard.
hope this helped

USB ports not working


I think the root issue of usb ports not working is a problem with your USB port's drivers no longer communicating with your computer. This often occurs when you install an update to your computer's operating system.

Acer Aspire 5050-5430 USB ports stopped working


Hi,
I hope i can help resolve your problem for you.
this may be a problem relating to your system device driver files.
Try This:-
go to My Computer/Control Panel/System/Hardware/Device Manager. at the bottom of the page you will see USB.
If you have any yellow symbols ( exclamation Marks ) then the driver has been corrupted, or installed incorrectly.
if you have a system restore disk. this may solve the problem for you. or recovery cd.
If you require further assistance, please ask.

Keyboard & mouse are dead


I just fixed this problem by doing the following:

Hard power-off (hold the power button until the laptop turns off)
Unplug the AC adaptor
Remove the battery
Plug in the AC adaptor
Hold ctrl and turn the power on. You should arrive at a black screen.
Hard power-off again, then turn the power on.
