toshiba satellite p100 bios 4.30 help please

heres the problem
my toshiba has 2 cooling fans, one for the cpu and one for the graphics.
im currently using bios 4.00 because its the latest one that keeps both of th fans running. if i upgrade to bios 4.20 or 4.30 the graphics fan wil stop running and my computer will heat up to unreasonable tempitures such as 75-90 degrees! at bios 4.00 its at a nice heat of 35-40 degrees. the only problem is that the old bios caues laggy and choppy preformance whale the new bios fixes that. therfore i need a solution.
specs
toshiba satellite p100
centrino duo processor
nvidia gforce go 7600
windows vista sp1
i forgot to mention,
i belive the 64 bit OS support is the thing disabling he fan in verson 4.20 and 30 because the fan works on the self test on the POST screen.

thank you for reading

 

anybody out there?

 

Yea, i have a similar model. I'm currently running 4.20 BIOS since that one fixed the performance problems in vista. Heres how to fix the problem. After you apply your new BIOS reinstall your video drivers. This means uninstalling your old ones, restarting, intalling your new ones, then restart again. This should fix your fan problem. If not you need to let your laptop "cook", meaning let it reach above 90 C degrees then your fans will kick in. I had to deal with this issue (along with many others on the Nvidia forums) and it worked. I havent bothered upgrading to 4.30 since it just adds 64-bit performance boost. This is in Vista. I am also dual booting with XP and this BIOS rocks in XP!

Sorry if I replied too late, hope this helped.

 

thank you very much
ill try that now

 

AHHH
didnt work, any help?

 

Did you try to let the laptop heat up until the fans kick in?

 

yes
it heated up to about 87 degrees and then the fail safe toshiba stuff shut down the computer

 

gorbafletch...i have the exact same problem,did u find out anything?
i know this thread is old.but i just updated it,and i called the toshiba company,the had no clue what was going on...they wanted to charge me $40 cause i called (stuff about warranty) i went a little crazy on them...eventually they didnt,and they didnt solve my problem.
but i have the exact same laptop u do.the same everything....
could u help me out?
or do i need to go back to the bios 4.00?

 

Hey guys. I have a P100 as well, running the 4.4 BIOS. Perhaps it is the fact that I run XP MCE2005 or the fact that I have a Canadian variant, but I have not noticed any fan problems since upgrading to the 4.4 BIOS. Mine was overheating as well, but that was (most recently, on the 4.4 BIOS) due to the fact that the heatsink was clogged.

There are known issues with Vista and the P100, but I'm not sure if they fixed them with the 4.4 release. My recommendation? Try the 4.4 BIOS and see if it works. Save your old one just in case, though.

 

Starting from BIOS 4.20 the Vista problems have been fixed. No more stuttering. Yea, one thing i noticed about this laptop is that it really gathers alot of dust. I air it out a few times a year to keep it running cool.

 

i updated to BIOS 4.20 ....fan didnt work...updated to BIOS 4.30...fan still didnt work...
ill retry BIOS 4.40 but i also think when i did it,the fan didnt work aswell....
but as gorbafletch said BIOS 4.00 is the latest one that keeps both fans running.
ill update,and let u guys know!!
thxx anyways!
