Thanks for the tip

Hello everyone.

I am probably on the right place (because i am the owner of Aspire 5745G with a i7-720QM). I have a question about cpu fan speed on my 5745G, namely can it be controled via BIOS ?

I spend last few days observing CPU temps (CORE TEMP) and relevant cpu fans speeds. I think that the CPU fan rotation speed is not adequate.

Example:

on start up :
cpu temp = 58 C
fan-speed =very slow (level 1)

after 2-3 minute (there is no user activity on notebook) :
cpu temp = 48 C
fan-speed =very slow (level 1)

there is light activity on laptop :
cpu temp = 54 C
fan-speed = a slightly faster than at the start (level 2)

there is moderate to heavy activity on laptop :
cpu temp = 70 C
fan-speed = a bit faster than in case of light activity (level 3)

there is extra heavy activity on laptop, all cores are on 100 % :
cpu temp = 81 C
fan-speed = very fast (level 4)

Then i started to use RW Everything and i was able to detect a bit who controls cpu fan speed (it is 50x0E, can be seen on a pic). Initial value of 50x0E is consistent with the value of 50x05 and it is value of 02. If i put the value of 13 into 50x0E, the cpu fan spins up much faster, i can say on the level 3. But, if the value of 50x05 is changing (because of cpu temp change!), the value of 50x0E is also changing (it drops) and cpu fan spins down, slower and slower, to the level 1. So, it must be manually set back to value of 13.

Now, the most important question for me is: can you modify the BIOS so i can control the CPU fan speed from BIOS ?

need your help .. i have a acer 5745g i7 with corrupt bios and the system is dead i just need a bios .rom file to re-flash the bios which i cant get. I believe you can get a copy of .rom bios file from a running system using
universal bios backup toolkit.

Hey, check two posts up, I think he's got the same computer you do. Further up in this thread are general instructions on how to flash from a brick, which might work with your computer, since it's a model similar to mine. Download the version from the website support, that way you're guaranteed it's error free and compatible.

ya but my acer 5745g is not starting up at all .. the only way i got is to flash the bios chip by taking it out of the motherboard and putting it into flash programmer hence flash programmer only supports the bios format of .rom or .bin and the available format on acer site is in .fd form . can u plz make a backup of your bios by universal backup utility and upload here ?? plzz

Hey does anyone have the software to use touch screen on this laptop or recovery disc? Would greatly appreciate it

thanks

You have to go to the start button and go to all programs and look for acer back or restore manager, it's there where it'll ask you to burn your own recovery DVD's.

The touch software is called "Acer TouchPortal V2" It's a 825mb file so I don't want to upload it unless there's a good reason to.
