I want to flash the BIOS of my Dell Inspiron 9400 but the battery died ages ago and I binned it.

I have the download from the Dell site which runs from Windows.

Can I use /forceit somehow?

What are the chances of me bricking the laptop - I'm flashing from A08 - A10.

The /forceit switch should work, but it appears you need to do it from a DOS window to make it really work..

I.e

1. Start> Run > cmd
2. cd \path\to\exe
3. Bios_Flash.exe /forceit

Thanks but the ONLY Bios update file fron Dell for the 9400 is the windows exe - there is no boot.zip as referred to in the article.

not sure what is happening, plse clarify :
-you can run windows, and you have the flash file, correct ?
then what is holding you from flashing it ?
btw - if i have no specific reason for flashing, i never do it.

OK,my Dell was overheating and I realised that a) it needed a good clean and b) the GPU fan for the graphics card wasn't working. I ordered a new fan and then checked for BIOS updates - I saw that the latest BIOS (A10, mine is A08)n addressed thermal problems with the I don't want to brick it.

I was looking for a bios update that I could boot from CD.

It's an Inspiron 9400 laptop which runs hot and anything more stressful than browsing causes it to shutdown. as I said the GPU (Nvidia Go 7900GS) fan is broken and I have ordered a replacement and will clean everything thouroughly and see how it goes.

The BIOS update says it is for the thermal profiling of the GPU , but I won't chance it - it ran for 3 years without problems.
