Acer laptop 3690-2972-- USB ports ?
My Acer laptop 3690-2972 lost all its USB2.0 ports. When I connect a known-functional USB2.0 device to any of the four USB2.0 ports, the laptop (XP32bit) does not even note a device has been connected.
I removed and reinstalled the USB drivers from system/hardware manager, but no change in the laptop's behavior.
Of course, I would like to image the system, especially since my last image was several months ago.
Any ideas about what to check, or attempt next? Despite its age, this laptop has been used very seldom, and was simply updated and its battery recharged. No surges from storms or abuse from rough handling, ever.
Acer, itself, does not want to talk with anybody outside warranty, by even email. :(:
I was afraid of that, but will keep you posted
Yes, I guessed I was in trouble with the Acer laptop when it refused to recognize the external USB driver plug. This is astonishing, since the ACER has had so little actual combat exposure.
Anyway, I'll keep you posted on my diagnostic-- I do have a driver CD, and I believe ACER still has these posted.
Thanks for being there, for a second opinion.
RESOLUTION-- USB Ports 2.0 "Come back to Life"
This is difficult to explain, but after putting away the laptop in its case, after discovering an intractible problem with all USB2.0 ports (would not recognize known good USB2.0 ext USB hard drive), all USB2.0 ports recovered completely on my next session.
This result suggests the problem was not the laptop, itself. USB ports >> normally << do not flip themselves off without a cause, as other, helpful posters pointed out. The more likely cause is a driver issue, since I recently replaced the ext HD with a new model which does not use the same driver as the original.
Of course, this is sheer conjecture, based on the little I was able to establish. So far, the problem has not returned.
