Hi all modders ! I'm posting in this forum because next to a flash of a Packard Bell Easynote MX51, i got the keyboard acting very strange // unusable. For example : when i press a key it write down another one completely different. When i saw this, i thought ... Let's revert back to the previous original BIOS ... right ... errrrr ... in fact "NO" ! For doing the revert flash i had to connect an USB keyboard which worked well. After seeing that reverting back to the previous original BIOS, the keyboard wasn't working too, i'm feeling a little confused Does someone knows where does this problem could be coming from ? PS : I verified the on-board keyboard connection on the laptop motherboard too ... even if it was clear that the problem wasn't coming from here. BTW, thanks for any suggestions !
