HELP! Can you revert BIOS update? dv2000 .fan gone crazy.

I recently updated my bios because HP recommended that I do so. Since then, my pc fan has been going non-stop and drains my battery quickly (not to mention what else it could be doing) the bios update was actually to help fix the fan even though their was nothing wrong with it to begin with but they recommended to install the update as it was "critical" and "Updates the fan control algorithm of the system to reduce the likelihood of future system issues"..I'm not sure what to do from here. Is their any way to go back to the old one? and if I can, how? and what is the old verison? Here is my specs and the link to the download.

HP Pavilion dv2214us (dv2000 model), Windows Vista Premium, AMD Turion 64x2.

Thanks

 

You simply download your old BIOS from HP's website and flash it again.

They're not kidding about critical. The update is supposed to make the fan run 24x7, because before the rest of the chassis was cooking while waiting for the CPU to heat up enough to trip the fan start threshold. The Intel notebooks have a similar BIOS update.

It shouldn't be putting that great of a strain on your battery, but lithium ion batteries often wear out before they're supposed to. HP has a battery check program, install it and see what it says.

 

Check if your notebook is in the HP's recall page.

If it is then your motherboard is flawed and was due to overheat and fail pre-maturely. HP just covered this up under the sheets by making the fans run 24/7 which is quite a dodgy band-aid fix. You shouldnt have to put up with it.

I suggest you contact HP and try get them to replace it.

Personally i would try my best to make the notebook fail, at least then theyll replace it with a proper functioning notebook.

 

I would highly recommend not reverting your BIOS... the reason the fan is now running all the time is because the fan algorithms were set incorrectly... The fan has to run to keep the board from becoming de-soldered and causing some more serious issues.

Here is a pic of a dv2000 which is running on the old BIOS.

 

Hi there FunnyX, I need your help, I got a hp pavilion dv2125la and downloaded the latest bios archive for my pc, I ran it and when the pc was shutting down to restart it never restarted, so I turned it up and when the charging bar appeared just before windows starts it appears a blue screen and then the pc restarts and does the same thing, I've tried to change and rewrite the boot sector with boot fix in the DOS, but I can not enter to the recuperation console because the new bios does not recognize my hard discs, even if I try to format the pc I can't it says there is no disc installed, what do you suggest me? help me please it is urgent!!

 

there was a rule here that if the bios ain't broke don't fix it, or just leave it alone. The bios fix is just there if ur really experiencing a problem with the system as the forums said. Mine was F.52, i didnt update it, and my fan behaves like the way it should. NO noise, just a minor high pitched sound as all pavilions do but i can live with that.

 

someone of you can help me with my problem? my laptop is dead, i am trying to find a way to recover my pc

 

juancargts: your dv2125la is an Intel notebook so it requires that Intel's SATA drivers be slipstreamed into the Windows installation CD or loaded from a floppy (if it'll even recognized a USB floppy drive at that point). If you can find your HP Windows restore discs, those should work too.

Your best bet is to hit F8 while booting and then select Safe Mode. Hopefully your Windows installation isn't too far gone and that'll work.
