Laptop Logo and Model: Acer Aspire 3640
Problem: This laptop arrived using the following complaint:
USB Not Recognized (among the USB products mounted on this computer has malfunctioned, and home windows doesn't recognize it. For help in fixing this issue, click this message).
Diagnosis, Cause and Remedy: Whenever a USB is placed into this laptop the next error will come out: Usb Not Recognized (among the USB products mounted on this computer has malfunctioned, and home windows doesn't recognize it. For help in fixing this issue, click this message).
One reason for this issue would be that the driver for that USB controller will get corrupted. The initial factor Used to do was upgrading the motive force for that USB controller. After upgrading the motive force, the issue remain. When the previous method, cannot solved the mistake, you have to repair or re-install the Home windows Operating-system because sometimes the O. S. (Operating-system) will get corrupted because of infections as well as other reasons. After I finished repairing the O. S., I switched on laptops once more and unluckily the issue did not gone away. Convinced that the corrupted system can't be restored simply by repairing the Operating-system, the 2nd step Used to do was which i reformatted this laptop wishing it may be restore. After reformatting laptops and setting up the particular motorists for that add-ons, still no luck, since the error wasn't removed.
I told myself "this can not beInch usually whenever you reformatted the Home windows Operating-system, will be normal again, however in this situation it didn't. Now i suspect hardware problem around the laptop, And So I made the decision to take apart laptops and free the system board all dust, as what I have stated on my small previous articles, the dust can also be one factor which in turn causes the system board electronic components to become shorted. Because when dust will get thick it is a conductor.
After taking apart laptops and removed all of the dust. I examined the current around the terminal from the USB port. The standard supply current for that USB port when it's working fine is 5v Electricity enough to energy up USB products. The current is simply normal once i examined it, This issue is a touch bit harder because I have already done several possible solutions which i usually accustomed to solve this type of problem. After doing all of the previous steps but still not fixed the issue, I ended for some time and additional evaluate what's really causes the issue.
Upon thinking, It found my thoughts that let's say the flow of current around the USB port that's produced through the supply current has already been deteriorated. For the information even when the energy supply current is simply normal, say 5 volts Electricity, however the current (measured in amperes) has already been deteriorated, still cannot supply enough energy to be able to result in the USB products work. The ultimate method I have designed to solve this issue was which i used an exterior USB hub 2. that is placed from among the laptop's USB port. After setting up the USB hub 2. and whenever I connect any USB products, it already works perfectly fine and also the USB Not Recognized problem was completely removed.
Hope this short article assisted you receive ideas about fixing USB Not Recognized condition in Home windows.
