Asus N53SV - upgrading bios without battery

Question

I want to upgrade BIOS, my battery seems to be broken as I am getting communicates that battery must be replaced or have at least 20%. So I cant do it using EasyFlash in Bios. I downloaded Afudos but examples shows that it uses ROM files and newest bios for my Asus is in this format: N53SVAS.215.

Cant I use Afudos of maybe there is some other way?

Solution 1

I have updated bios for a ASUS F75A (2012) without battery.

1) Download the new bios (for me X75A1AS.412) and copy it on USB key (FAT32).

2) Start and enter bios, then in bios menu : "Advanced" -> "Start Easy Flash"

3) When the system will display that you can not update the bios because there is no battery, on your keyboard you enter "risky"

Solution 2

DISCLAIMER: I do not recommend doing this for obvious reasons. If your machine loses power midway through a BIOS update, you're likely left with a brick!

Firstly - ask yourself if you really need to apply a BIOS update? Why do you 'want' to? Is there actually something wrong with the machine fixed by the latest update?

1.Show system serial number on setup menu

2.Add New CPU function support

3.Update CPU microcode

4.Fix sometimes system can't boot after press power button.

5.Update EC firmware

I can see 4 being an irritation, but is it worth risking a completely dead system for?

If you still want to go ahead, try this at your own risk.

The download page for your machine lists the bios utility to use as WinFlash.

You can run this with a command line argument, usually /f or /forceit to bypass checks.

Ok I will go now for a new battery. I must upgrad bios as it is the last idea I have as for the error: A disk read error occurred Press Ctrl+Alt+Del to restart. This error is after cloning my WIndows7 to new SSD Crucial BX100. I am trying 2 days to start the system without results.

Confirmed for N56VZ. Just type "risky" on your keyboard after entering easy flash in BIOS.
