Had the computer about 3 days, and was receiving some strange errors reporting unrecogized USB devices not recognized and a buggy USB driver. 3) Waited, pensively, for 5ish minutes (read several places to wait for 20 minutes; I didn't) 4) Plugged the power cord back in (I did NOT reinsert the battery) 5) Holding down the Insert/Scroll button, I held the power button down for 20-30 seconds.Then attempted to reboot and it finished flashing bios like it was supposed to do. After it successfully flashed the bios I plugged everything back in and works perfect again! I almost open my laptop just to find the reset button on the bios battery, and then I searching for answer you just need to change the boot mode from UEFI to Legacy.. Note that you should first extract from the BIOS updater exe tool the BIOS ROM, then rename your ROM as BIOS. Use crisdisk tool to create a bootable diskette and a bootable floppy with the files phlash.exe, and (your bios file) will be created for you Held Win B key (other report the key combination being Fn B) plug in AC adaptor Push the power button, with the two other buttons still down.If the power led start, release the `Fn'and `B' button. Your computer will reset itself and start in Windows!! Powered on, it did some beeping then I saw the light access of my flash drive, when the light stop I released win b, it did some beeping then the cpu fan quick in (I knew then I was in good shape because it's the sound it make when the bios is flashing) then it stop and more beeping for 30 secs then it powered itself off .. If the booting doesn't succeed, try a different timing on releasing the `Fn' and `B' button.
