Dell inspiron n5010

Good evening to everyone,

First time posting here and if it wasn't for the problem I have I would not even post here. :)

First to you dell - this is my 5-th laptop from dell - boy I loved my previous 4 ones - no problem what so ever, all running different distros of Linux. Thank you for the those! 

My 5-th laptop on the other had is n5010 - running on ubuntu 10.10 - no problems so far - all the drivers are found and it works great, except two issues :

1. The cpu fan is like a hair dryer :). It makes more noise then "kills" the heat. The cpu usage is under 2%!! and the fan is so loud like the laptop is using a couple of extremely resource intensive tasks. This is obviously not a Linux kernel issue with n5010 - lot's of people using windows have confirmed. 

May be a bios update could help - I thought. Tried to get one but without luck so far. Here is what I did:

$sudo apt-get install libsmbios-bin

$sudo getSystemId

Libsmbios version:      2.2.26

Product Name:           Inspiron N5010

Vendor:                 Dell Inc.

BIOS Version:           A04

System ID:              0x0447

Service Tag:

Express Service Code:  <ADMIN NOTE:Service tag & Express service code removed per privacy policy>

Asset Tag:              

Property Ownership Tag:

Went to the : http://linux.dell.com/repo/firmware/bios-hdrs/

But the systemID is not present. So dell of other users of the forum, may be someone could give me an indication of how do I upgrade the Bios on this laptop from Linux?

Best Wishes,

Eugene.
