Can someone please assist with this please. I've provided two dump files using Xgeco T48, one is the read and default saved and other is the Flash saved option, they're labeled according.
Thank You.

This worked perfectly.
On initial boot it restarted several times which is normal, then it booted straight to bios setup and i permanently disabled Absolute Persistence.
i then reloaded Windows and everything seems to be working perfectly, I'm actually responding to you from the same laptop.

Question #1: I have 6 more of these laptops coming in with the same issue, can I use this same bios file you provided to fix those as well?
Question #2 Can you direct me to some information or software so that i can learn do these modifications myself?

Anyways i really appreciate the help and the prompt responses.
