440s errors and now BSOD

440s came preinstalled with win7Pro, used RDVD for win8Pro then updated to 8.1 Pro.
After initial install, was copying some files off old laptop and was planning to put on new one left 440s  on to find later it had restarted and had an issue with the HDD ( SSD) - error 2100: Detection error on HDD0 ( Main HDD), press esc to continue. Then day later it suggested it had a non genuine battery which would not charge properly. Then later same day started to blue screen whenever it was either hibernated( via shutdown menu) or put to sleep ( close lid) - suggests it due to SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (vwififlt.sys). Lodged ticket Monday for initial errors expecting lenovo to contact me to do diagnostics to confirm HW is OK, now Friday arvo they still have NOT contacted me despite numerous updates to the ticket giving as much info as I can. Anyone had similar issues?
Also ran all windows updates, Lenovo updates etc, 440 is fully patched in all respects.

Hi Collew,
Welcome to Lenovo Community Forums!
I’m really sorry to hear that your Lenovo ThinkPad T440s is having multiple issues.
If the machine started showing 2100: detection error on HDD0, try reseating the HDD and check. Also, try using the HDD with another system if possible and see if the error appears. This error comes up usually when Hard disk drive is failing. If there is any critical data in your HDD, I would suggest you to take a backup at the earliest.
Regarding the battery not genuine message, try updating the BIOS and power management driver. Install Lenovo settings dependency package and check if the issue gets fixed.
BSOD seems to occur due to vwififlt.sys (Windows Virtual Wi-Fi Filter Driver). I would suggest you to reinstall the Wi- Fi drivers completely from device manager, reinstall and check if BSOD occurs.
Best regards,
Mithun.
