Good day folks. I'm hoping someone can provide a bit of help with this Acer laptop I've got here, since it's got some pretty strange symptoms which I can't seem to identify the cause of. It's actually got several problems and I think they may be related somehow: first off it hangs on the Acer logo whenever a USB drive is plugged in. If you leave it alone long enough it eventually resumes, but doesn't actually detect the USB drive as bootable, making booting from it impossible. I tried several drives thinking perhaps there's something wrong with one of them, but no: Hirens, memtest, windows, all have the same exact behaviour.
Thinking it's a BIOS issue, I grabbed the zip file from Acer, which I also attached for you to see here, simple and convenient enough, extracted "KM2X64.FD" from it and copied that onto a FAT32 USB drive, as per the instructions on other forums. It made perfect sense, since I distinctly remember doing this to an HP laptop before and it worked, so at this point I was fairly confident this would work. I plugged the drive into the laptop, held down FN+ESC and plugged in the power adapter. Amazingly, it worked: the screen remained blank while the LED on the drive flashed for around 1 minute. When it stopped, I pressed the power button to turn it off, removed the drive and tried it out. It worked: the laptop still powered on, Acer logo came up and sure enough, the BIOS version was now the one I had on the drive. But.....sadly, this is where my luck ended, since the problem was still there: USB drive still caused the system to hang and doesn't get detected.
Is this a hardware issue ? Oh yeah, the USB ports DO work since USB keyboards work just fine, so it's probably something more complicated going on. Someone before went ahead and even replaced the NEC TOKIN ! Any thoughts on this ? Thank you.
