There's a nice recovery procedure for the BIOS at [macles](http://macles.blogspot.com/2008/08/acer-aspire-one-bios-recovery.html). 1. download the latest BIOS from [Acer](http://support.acer-euro.com/drivers/notebook/as_one_150.html) 1. format an USB stick with FAT32 / VFAT 1. put the files `FLASHIT.EXE` and `ZG5_`*version*`.fd` onto the stick 1. rename the ZG5-file to `ZG5IA32.FD` 1. now connect this stick to your AAO, also connect the battery and the power supply 1. hold Fn-ESC down while powering on the AAO 1. release when the Power-LED starts blinking 1. (maybe press the power button to initiate the process)[^1] 1. :warning: **DO NOT INTERRUPT THIS PROCESS!!!** :warning: 1. wait until the blinking ends and the AAO reboots a bit later Somehow an A150L with the v3114 BIOS didn't let me update it to v3304. The Power-LED was blinking and the LED on my flash drive flashed but after a few seconds, the A150 rebooted and the BIOS reported still the v3114. [^1]: I'm not sure whether this is neccessary as I don't remember doing it when recovering my bricked A150X *[BIOS]: Basic Input/Output System *[FAT32]: File Allocation Table, 32bit *[VFAT]: Virtual File Allocation Table *[USB]: Universal Serial Bus *[AAO]: Acer Aspire One *[LED]: Light Emitting Diode
