Acer 5920 bios 3808 question

I have some question for people who update bios in acer 5920 from 3805 to 3808. Does the fan beheaves simmilar like in 3708 version (constant sound) or rather like in 3805 version (slows down than speed up and after few seconds the same repeats)?

 

New BIOS? Never heard about 3808 .BTW I'll try

 

BIOS 3808 Change log:

 

My fan is working the same with any BIOS update I have done. To be honest I don't see any difference what so ever with the BIOS updates (I have checked the BIOS version to see if the update has worked). The only thing the updates do, that I can understand, is to make the motherboard compatibille with the new Intel CPUs Penryn. I think there might be a problem with the heat coming out from your GPU or CPU. You might need to apply some Artic Silver or something similar on them.

 

i just upgraded from bios version 3702 to 3808 and the fan runs the same but my laptop cpu's averages a good 10 degrees (F) hotter, and the hd at least 15 degrees hotter

 

Well I'm quite sure that not only in my laptop fan behaves diffrently with bios 3708 and 3805. Here is an example: http://forum.notebookreview.com/showthread.php?t=217959&highlight=3805+fan

 

Please could you let me know, what is :
1. Re-Enable VGA LVDS Spread Spectrum.

Ok I couldn't resist and I just checked this bios. Unfortunately fan works the same way as in 3805 version. I'm quite surprised that for exemple on CMWelch laptop fan works differently. In my case 380x bios is unacceptable. When fan still changes rpm I can't do anythink. It's very annoying. I guess I have to go back to 3708.

 

@ OP: my fan depends of power settings -- for gaming I setup profile with CPU at max, for typing I set CPU to medium or in certain cases (max battery) to low.

Fan corresponds to those settings -- barely working at low, sometimes at medium or constantly at max.

Flashed from 3708 --> 3805 --> 3808 and working with without problems (I have model without turbomemory).

 

Well It seems that not everybody with 5920G have this problem. Maby it all depends of hardware revision? Still, I have no idea how to resolve this problem. I have 6 moths old 5920G with T5250, 2 GB ram, 8600M GT and Turbo memory (no HDDVD)

 

Thanks
Is it useful this?

 

I still cannot upgrade my bios under windows vista x64 with neither of the 2 new (38 series) bios. Acer has not answer my open ticket to them (almost a month now) and i am loosing hope it will. Maybe i should install xp in an external hard disk to check it....

I have admin rights if so ever since i have try to do it under the admin account with same results
Thanks to Adam20 for the solution

 

It's not enough to use administrator account. Vista use UAC so by default every program has only normal rights (no aministrator rights) even on admin account. So to run program with admin rights please left click on it and choose run as administrator.

 

I too can't update with Vista x64 (SP1) - running app as administrator and logged in with an account with admin privileges also.

This appears to be an issue with Phoenix Secure WinFlash being 32 bit app and the PHLASHNT.SYS driver being blocked from loading...

 

I read somwhere on this forum that this flash program is just incompatible with vista x64. So the only solution is to update bios from 32 bit Windows

 

Yup, this is the case. Secure WinFlash was last updated in 2005.

 

a question for all those who updated to the recent BIOS revisions. do any of them give the older 5920G Penryn support capability? I'd really like to upgrade my T5250 to something like a T8100 if possible.

 

Of course it does, check the release notes.

 

I also have vista x64 installed and therefore can't install the latest bios. The only way this can apparently be done is by using a DOS version of the bios and putting it on a floppy (or in the 5920's case, burning to cd).

Does anyone have the DOS version or bootable file? Or even another method?
