i just wanted to get maximum battery life out of my laptop, since it isn't the Timeline version.

and it runs quieter too now

great to know.. means its working well for you..

dont underestimate the powwah of UV.

got any battery life difference?

i need to allocate more than 5hours of my life to test the battery life.

i shall do so when im bored

8 hours+, suppose. Hahaha

ive done undervolting my Z, its pretty cool and good to lower down the temp.
but now, no more since im feel too lazy to redo the same procedure after formatting my Z. and also, doesnt make real difference to me since im aint really gaming on notebook and P variant processor is already at decent temp.

just my rant

User ID: lcct
Laptop Model: Acer Aspire 4540
Processor Model: Turion II M520 @ 2.3 GHz, 1800 MHz HT Link, 2x512KB L2 Cache, 45 nm, 35W TDP
Stable Undervolted Voltage:
P0 2300 MHz: 1.050V
P1 2100 MHz: 0.9875V
P2 1500 MHz: 0.875V
P3 1100 MHz: 0.800V
P4 800 MHz: 0.725V

Notes:
- Using K10stat, command line options used in startup folder: -lp:1 -StayOnTray -ClkCtrl:2 -nw
- Each of the p-state was tested stable using prime95
- Temperature drop at full load: ~7°C (65->58), at idle: 0°C (45)
- Battery life increase: 0% (idle) to 27% (full load)

ok, from my normal usage with brightness level 3 and power plan "power saver" is tweaked a bit, i managed to get the laptop increase its battery life from 4hours+ to 5~6hours.

now that's what i call achievement.

i will do it accurately next time with Battery Eater

how do you all undervolt the laptop?use any program?mind to share with me too

Can you please refer on the 1st post. There's a Link to the Undervolting guide which uses RMClock to undervolt. Do read the guide carefully in order to succeed in the Under Volting procedure. Good Luck!

refer the first post, there's got link to the guide.

After undervolting, now my HDD is hotter than my CPU..

Very pleased...hehe

Do you mean the HDD become hotter than before? or The prcoessor is cooler than the HDD?

You shud get a cooler pad to cool the hdd ..

I gave it a try. But at the lowest PST, my processor is already at the lowest voltage that RMClock can set. So since I'm using my computer at the lowest multiplier and voltage all the time through Window's default power management, this doesn't give me a cooler PC or more battery life.

To achieve those low temps, I removed my back panel, and is using my self-improved CM Notepal cooler.

Oh.. so u run without using the backpanel? cool.. gonna try that too soon

Won't it get dusty easy without the back panel?

Yes without backpanel you could achieve insanely low temperature, I even managed to get 38C CPU and 44C GPU temperature in non air conditioned room. It could get dusty but don't worry unless you could used it on dusty environment. Using notebook cooler minimises it

I just hope nothing went wrong after I test undervolting few days back, cuz feels like my laptop battery life getting abit shorter. Maybe I just too sensitive or something =p

About the back cover, I tried several times to remove my UL80VT cover (because my hand was itchy lolz), but failed... I have no idea how the cover been assembled together... Pull out all the screws but still very tight, lots of 'traps' around
