Dell Inspiron 15R 5521 BIOS update error.

OS: WINDOWS 8.1 64-BIT

i am having a battery problem so i am wanting to update my BIOS to troubleshoot it.

My current BIOS version is A05 (3-jan-13).  I want to update it to A14.

But i am getting ther error message 'allocate memory for security flash fail!'

The drive where windows is installed has only 5GB of free space.

Could it be becausr of this?

No -- 5G is more than enough free space for a BIOS flash.  Is the system failing to recognize the AC adapter (F2 at powerup to check)?

If it is, the BIOS won't flash - this is a hardware problem a BIOS update won't fix -- either the adapter, the DC jack or the mainboard is bad.

I just checked by pressing F2 at bootup, next to the AC adapter type it's written 90W.

So i guess yes it does recognize it, also the adapter powers the laptop when i removed the battery, so the adapter is good.

U mean it's because of the faulty battery that im getting this error?? Actually the battery is charging only to 50-60%, after that it says 'not charging'.

I checked using F2.  Next to Ac adapter is written '90W'.  So i guess it is recognizing it.

Also the laptop powers up when i use the adapter to power it (with the battery removed).

Also, 'this battery is performing normally' is also there when i checked for battery.

Actually, the battery is only charging til 50-60%, after that it says not charging.

Dell extended battery life is disabled so i know that is not the cause of it.

What might be the cause of that error msg?  Why is the update not running thru?

Update the Intel chipset driver (link below).  Then reboot and retry the flash.

Thanks ejn63 Smiley Very Happy...the intel chipset driver had to be updated first.

And the BIOS update was a success.

Now i just have to see if this solved the battery prob.

Thanks again Smiley Happy
