upgrade lg s1 from t2500 to 7600

i will add my experience about upgrade my LG S1 laptop from T2500(2.0GHZ) to T7600(2.33GHZ)
the problem was in overheat and shutting down because i forget to add some thermal paste between the T7600 and the heatsink, so i open it again and put some white thermal paste the temp. down very much about 4 degree on full load and not coming overheat ANY MORE so, ( not safe to install laptop cpu without thermal paste)
NOW: on idle the temp. 50-55 degree on full load the temp. 72-84 degree

Second i install 4GB ram (667) the bios just see 3.2GB ram ((bios rkywsf33 19/9/2007)) NO NEW LG S1 UPDATE BIOS

Third i upgrade the Fujitsu 100GB hdd to seagate 250GB-7200rpm-16MB cashe

Now LG S1
oparating system windows 7 (32)bit subscore:
cpu-T7600 2.33GHZ.................................5.7
ram-4GB (3.2GB USABLE).............................5.7
ATI Mobiltiy Radeon™ X1600(256ram)............4.9
gaming graphics.........................................4.6
primary HDD..............................................5.9

 

This is because you need a 64-bit operating system.

 

sorry ronnieb , but windows 7 ultimate (32-bit) shows untill 4GB ram but my problem from BIOS cause if i enter the bios by (F2) bios show install 3.2GB ram

 

That’s cool... mine stock except upgrading the Ram from 1GB to 2.5GB ….

Still happy with the purchase


I was at LG service department the other day and they told me that Bios on S1 will see full 4GB but windows (32bit) will only use up to 3.2GB unless it was 64bit then it will see all the 4GB….
I know there was a bioss update cuz I remember updating it a year ago… next restart I’ll try to post the version I’m using…

 

sorry, but even if you find a bios update, i don't think that'll solve the problem. 32 bit windows is unable to address 4 gigs of ram, regardless if it shows it or not.

 

sorry but your bios is more dated than mine cuz i have Version: RKYWSF1E, Date: 09/26/2006 ....

 

1. Where did you get the New CPU from ?
2. Can you benchmark the new performance ?
3. Is it possible to upgrade the Graphic Card ? (I think X1900 Mobility is our only possibility due to PCI Express Ver 1.0 us)

 

BTW,
Note that you need to add another 256MB to your actually reported RAM since the Graphic Card takes 256MB from the Main Memory.

 

hi every one i bought the New T7600 from laptopdemo(ebay) he is good seller but slow shipment take about one mounth to arrived to (middle east) and about performance i saw the deference in windows 7 ultimate booting and photoshop CS2, NO WAY to change the video card in LG S1
i hope if some one can share us the latest LG s1 bios update (rkywsf33 19/9/2007) just see 3.2GB of ram

 

I'm using Win7 64x on a T7200.
Had already updated my bios ( http://rapidshare.com/files/147516968/LGBIOS08.rar) too and still can pass the 3.2GB.

Any news about this issue??

Hmmm, I recently opened my Old LG S1 and I am pretty sure the cpu was soldered....weird.

 

is T7600, the best CPU the LG S1's MB can use...?

 

YES , LG S1 MotherBoard is i945PM,Front Side Bus (667MHZ) Processors support until t7600

 

I should have demanded a MB upgrade from LG, when they charged me 400$ for a MB repair (which was their fault in the first place).

thanks...

 

hi, this thing that u saw soldered in the main board it's the GPU(video card
) and the Intel i945PM chipset

 

I just got my T7600 & 4GB installed with a new Win7 64bit - what a difference!

but I seem to be missing a USB driver (I have nothing connected)...
any clue?
