Don't put on bed or other soft surface, it will block all the vents. Also with the current weather, I think 50 normal ke? Heh, y laptop so fussy one.

20 sec startup is really good lah aiyo! C2d?

I have ati control center and the touchpad program set not to start also but i notice after everything loads there's a short period the hdd light will blink nonstop. No idea what windows is doing.

when used for few hours..then the heat will just build up..mine will shoot up to 59 degrees and stay there.then can feel the heat at the keyboard.
BTW anyone hadopened any laptop before?i'n still new with my laptop.dont know the design inside.cant really figure out hot to make it cooler


Added on February 12, 2007, 2:27 pmi just recheck the restart thing..really true..before i restart..it was 40degrees..after restart now is 52 degrees.

my startup is basically nonexistant. boots less than 30secs or so. never timed it cool2.gif

pre installed windows usually came with a bunch of stuff you don't need. thats why its free. trash em

another way for cpu cooling is thru undervolt the cpu voltage, read here for info.

yup yup heard bout that d .... toshiba provides a software to to help save batt ... same thing as the undervolt program ...

but i dont like running low on processing power because i dont like to wait ... unless i leave my laptop on at night when i go sleep...

dun like to wait? rclxub.gif i suppose u are talking about downclock/speedstep the cpu freq? hmm.gif the undervolt process is to reduce voltage while still maintain the same freq, thus there is no impact on the performance icon_idea.gif

i heard about the ondervoltage thing from my uncle too. He had worked in the computer field for more than 20 years. i actually consulted him before buying my laptop.he told me bout this undervoltage thing and some chips are ultra low voltage.

normal chips will use 5 volts and 0volts as I/0 in the processor.un ultra low voltage case it usses 1Volt and 0Volt...the advantage is..energy saving lo.BUT !!!!..there is 1 problem...

if 5 volts losses 0.5 volts due to error..still got 4.5 volts ..which the processor still can recognize the bits..but if 1 volt losses 0.5 volt..then the processor dont know wether its I or O.

of course there is always correction can be made.need more $$$ for technology lo.thats y ultravoltage chips are always expensive.

so,if normal 5volt chips are being programmed to be lower voltage..then the chips might have difficulties in recognizing the bits.and might cause alot error.coz they are not designed to be like that.

modifying something that are not made to be cannot perform 100% perfect and might damage it too.

thks for the info, u r rite as i sought for the pro & con before i've decided to go for undervolting. in general, it is much much safer than overclocking thingy as undervolt excessively will only cause system hang (due to error in data handling as what u mentioned) and that's it, hence ppl recommend to undervolt only 10 to 20% of the stock voltage, and run some stress test if u want to feel more secure. Happy undervolting~ biggrin.gif

i think undervolting the CPu is not a good way to save power or reduce heat la,it will just come back to the same ,,,plus more damages.how much power can we save throught the undervoltaging 10-20%?just not worth the risk to take .

back to the heating prolem, i found out that my laptop cooler has 2 studs to lift the laptop higher abit from the back.this makes the laptop abit slanted to the front and the space below the laptop abit bigger.

i think all laptop cooler has this, but one of the stud is on my battery. The battery is attached to the laptop through a thin plastic slot and then being locked.if i continue to let the weight of the laptop to sit on the battery slot..will the plastic break?currently i took out the studs and my laptop lie flat on the cooler pad.

i think alot user will face the same situation like me.any comments?
