Usb ports not working

Hello, i bought my Acer about 10 months ago. Im in Iraq so it is very dusty but i still seem to be having more problems with my notebook than most people with older model laptops!! First my disc drive stopped working all together a couple months ago and i just finally gave up on it and started using my dvd player. My most current issue, though, is the 3 usb ports on my notebook. None of them work! Nothing that i plug in is recognized on the laptop. I tried to troubleshoot on windows but nothing works. Please help!

Re: usb ports not working

Maybe they are already fried. Try putting a device like a USB based fan or mobile charger that just uses the outside 2 points. If that does not work then some fuses are blown on usb bus. Your USB may need to be checked enabled in BIOS.

In case you find USB is dead then you can buy a PCMCIA based USB card.

Re: usb ports not working

Is there any possibility that they could have been inavertently turned off in the bios? Forgive me if this has already been addressed...but if you have not checked it, reply to me and I can walk you through it.

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!

You need to run a repair installation with the original windows disc. If you do not have one then using the recovery disc and completely reinstalling windows is the best option.

Acer Aspire 5050-5430 USB ports stopped working

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.

OMG ... i was completley distraught. i bought my ACER ASPIRE LAPTOP 6 months ago when i was trveling in italy ,im in austarlia. I use it to run my online game ; » - and has all my files.

When i got the black screen o death i first am here to the boards finding nothing i was further distraught..

I AM HAPPY TO TELL YOU MY FRIENDS, that i am typing this on my lil baby

Heres what you do....

* you need usb disk drive
* a second computer with internet access (can be work cafe friends place)
* a file you can download from acer or search yourself called

Format your drive in fat (*note i tried fat as directed in a number of manuals though then tried fat32 and it worked then though suggest you try fat first *shrug)

open zip file and copy 3309.fd and the fla.exe to the usb stick

rename 3309.fd to ZGIA32.fd

Turn off your laptop making sure that both battery and power supply is plugged in and attach the usb stik/drive.

hold down FN and ESC keys and press the power button, continue to fold FN and ESC keys for 7-10 secs then release - at this point the power light should be blinking and you should still have the black screen of death.

press the power button once while its blinking - this will initiate a bios update * DO NOT PUSH ANYTHING AFTER THIS

After 2 mins the aspire should reboot itself , wait for about 7mins if it dosent before rebooting manually

Took me three attempts as i just wasent doing something right though TA DA!!!!!

and i still have my files. yeah team take this and run, hope you havent spent money yet smile.gif
