I have a problem updating the Bios. Reason for update is common black screen and currently I have 2.04 loaded and I try to update to 2.06. Laptop is in factory settings with Win 8 in it. I have loaded the new bios version and it basically works well using windows update but in the end when the laptop is restarting it ends up to black screen. Now you have two options to run battery out or use that tiny hole behind to "cut the power" (you can not remove the battery in this model). After restarting the laptop says "invalid bios image etc." and pressing any key will restore the 2.04 Bios.
I have actually three very same laptops and in another one windows update work just fine. (That did not have black screen problem)
I have tried to update using usb-stick, but I do not exactly know how to do that. So please if anybody can help it would be highly appreciated.
