I think as far as all owner concerned, i would like to share
some tips and guide for decreasing boot time... first of all, i will highly recommend you go and do a CLEAN FORMAT for your window.. it's a best way to clean ur bloatwares or wat so ever programs and return your laptop to a clean state and u r the one who determine wat to install in your laptop... I, did you this way to decrease my boot time, and hypothesis accepted...

boot time significantly dropped...
well... first of all... You will need to do back-up... 5 DVDs' ai recovery burner... if u dont know how, you can refer to user manual, or e manual...

It's kinda easy,but it took 1 hour and twenty minutes for me... okay... wat's the purpose of doing tat back up? First, it's for your recovery in case ur recovery paritition not working, u can use those 5 dvd's to do recovery.... okay so... IF YOU DID BACKUP, then proceed to second step... It will be reformat your window 7 ... but before tat, there's a optional step before u reformat which is insert your driver disc, try to see list of program/drivers... i think u need to click advance in order to view the applications/drivers tat were preinstalled... okay.. so after u get to know and ideas on which programs or drivers u need to install, then u r good to go....
All rite, reformat is kinda easy...

First of all, you insert the win7 disc into your dvd room.
Download them from here if u don hav. burn them into dvd by using ImgburnThen you will reboot your laptop. when the black screen appear, press F2 to enter bios setting,
and then you will go to boot tab, and find boot option #1, hit enter and change it to ur dvd room or Blue ray room, for my model, for instance, it shuld be Slimtype DVD A..
Then you will hav to hit F10 to save and exit...
so well now it will reboot and then a black screen with following words should pop out "press any keys to boot from CD and DVD" then u will hav to press any keys,
then will enter the setup... windows will gonna load the files... and starting windows...
then it will gonna ask you for language u wanna install, time and currency format, and the keyboard and input method... set that, and click next...
(do note that the window resolution might get low, instead of HD+ during reformat for i5 sf) and then click on the install now.
then the screen will show setup is starting... read the license terms and accept it and click next....
and select custom (advance),
so well, at here... you shall see three partitions... first it should be
system recovery partition, 25gb of primary partition...
DO NOT DELETE THE SYSTEM RECOVERY PARTITION, you will need tat for system recovery... Accept if u really need tat 25gb... i would say no.
don touch the recovery partition...
and you should see second partition, usually named as OS (C:) and third partition Date (D:) for me...
so if u wan a clean format, you should delete tat two partitions, OS and Data D or wat so ever local disk or wat is named for your partition...
click drive option advance to delete the partition...
click okay if a warning pop out asking you whether u confirm wan to delete the partition...
all rite, then u should see Unallocated space... select it and click next...
once u clicked next, it gonna show window is installing... copying windows files, expanding window files, installing features, installing updates, and completing installation... (note that the expanding might take some time, so relax during window expanding the files) for me, it took around twenty minutes to done this process.
okay... now after the installation, the window is gonna restart,
PLEASE MAKE SURE TAT YOU DONT CLICK ANYTHING WHEN IT SAY PRESS ANY KEY TO BOOT FROM DISC OR DVD.
then starting windows,updating your registry settings, setup is starting services, completing installation,
setup will continue after restarting the computer,
AND REMEMBER DON CLICK ANYTHING AT THE "PRESS ANY KEYS TO BOOT FROM CD OR DVD" setup is preparing your computer for first use. then type in ur name and computer name, click next..
then for password, if u don wan any, leave it blank and click next.
your product key, key in the product key and click next, use recommended setting, set time and date click next and select your network...
after u enter the window, congratz.. reformat is done... a clean installation of windows....
okay... so after reformat your window, you might wan to
repart your partition...
go start
then right click my computer
click manage
click disk management,
you will see the big partition.. it should be 25gb of primary recovery partition, then 100mb of system reserved after u reformat, then a big parition..

it should be 571gb
so you right click on the 571gb, then click shrink volume
enter the amount of volume you wan to shrink
then u will see free space,
right click and click new simple volume, click next, next again, then assign the letter u wan for the new drive, then click next then next then finish...
then u r done...

(
Dont forget to go in your BIOS and adjust back the boot option 1 back to ur HDD instead of slimtype DVD.blue ray) so tat u get rid of the "press any keys to boot from cd or DVD"All rite, lets proceed to the installation of driver/softwares from your disc.
tat's kinda easy...
first insert your disc into your dvd room/blue ray room
then run,
then u will see all the ticks on the recommended applications and drivers, from here u can tick or untick the programs u wan or don wan to installl
Personally, i installed all the drivers accept IRST, and then for recommended applications, i install INF update driver, touchpad, bluetooth, wireless console 3 and P4Gear...
that's all...

You may tick any program u need...
after tat, click start, then it will ask install now? you click yes, then wait for the drivers to be installed... it will be automatically installed, frequent reboots, and then you might need to get a cup of tea or coffee at the mean time, for some of the programs or driver, it needs you to click okay if it ask you whether you want to reboot or not...

after done, you can go start > then right click at my computer > then manage, then click device manager, see if any unknown device.. if no, then congratz.. reformat and install driver is done...

dismantle n cooler pasting guide ----> credits go to htpkevin and thanks soloinruds for reminding...Ok, first thing first, u turn to the bottom of the laptop. Unscrew every screw u see, take out ur harddisc(the whole thing with the metal thing), unplug ur ram also. Coz there is a hidden screw under the ram, this screw secured ur touchpad one. The wifi card u might wan to plug off the black and white wires. Then remember there are 3 more screw under the battery(if u are plugging battery now). Then u can take a flat screw driver to pry ur dvd-rom out which will make ur disassemble much easier(just one screw securing the dvd-room at the back).
after u unscrew everything single screw ady, flip it back and open up ur lid. Now u will take out the speaker grill first. U might need something sharp coz the grill fit nicely. U need to pry off from both left and right top corner. U might need to use a bit of force coz there are hinge under it. after the speaker grill come off, there are a few more screw securing the keyboard and the speaker. As usual, unscrew all of them.(make sure u put ur screw accordingly so u know how to put it back later). After the keyboard come off, u will see a ribbon attached to ur keyboard and touchpad. Unplug them both also. Then there are a few screws securing the metal with the motherboard. Unscrew them also. Ok, now u need something sharp also, u need to start prying the edge of the whole front plate(the place it hold keyboard, the touchpad and all). There are hinge all around it so u might need to go slow and take ur time.
After u take out the whole thing, ur motherboard is pretty much exposed. But the usb port vga port are still attached to the left side of ur laptop. So u might wan to push it a bit from the outside then ur motherboard goes free xD.
Now the only wires that attached to the motherboard should be the screen only. For my case coz it seems too fragile so i didn't unplug it. I just let the screen attached to my motherboard. Now the heatsink for gpu and cpu are beneath the motherboard. Turn it over, then u should see them.
WARNING(!!!!!) this is very important, u should see a yellow sticker for warranty one stick somewhere around here(mine one was sticked on one of the cpu screw). I took it out slowly and stick it somewhere else. Don break this sticker, its warranty sticker.
WARNING(!!!!!)before u unscrew and take out ur heatsink, becareful, next to ur cpu there is a thing black in colour that has a shape for a flat screwdriver one. That thing basically locks ur CPU in place. So basically u need to use a flat screw driver to turn it to the other side to unlock ur cpu. If u try to take the cpu out with this thing locked u might breaks ur cpu.
So u are pretty much there xD. Just take out the heatsink, clean it properly, make sure u wipe the remaining thermal paste clean. Then apply ur new artic cooling mx-4 xD. Don apply too much, if too much it might cause negative effect. Then after that slowly assemble back ur laptop xD.
