Lenovo K320-30192GU slow USB data transfer rates

2015-10-06, 19:40 PM

I am trying to troubleshoot a C 200 AIO that was given to aclose friend as a gift.Computer bought in Chile.Originally with w7 starter.Arrived with W8 Pro.

Issues are very slow speed rates with all USB ports and slow file transfers to a network computer same LAN segment.


One curious thing is that ths installed BIOS is version DJKT09AUS dated 06/4/12 ( computer MFG date is 24-June-2012 ).This version is NOT in the LENOVO EOL web site which only shows Version d9J914AUS dated March 2011, and no further updated BIOS versions published.


Happens on W8 pro, W7 Ultimate x 32 or x64 ....tried all of them.


Gone thru a lot of seaching ....the USB controllers  do not show as ENHANCED USB2 as is many other cases.


Stranger still is the fact that file transfers computer-to.computer are also very slow, but internet downloads are perfectly normal, as well as all other functionality.


Any help will be very helpfull indeed.
