There is more to it than that, if you just remove the screws on the
bottom , youll crack the case... first remove the battery, ram and
hard disk., and wifi card. then just above the keyboard, theres a strip
of plastic about 1.25 inches wide that spans the whole bottom of the
screen... pry this up and put it to the side. then remove the screws
holding the keyboard down. remove the keyboard being careful not to
damage the cable. now remove the screws holding the screen down(top and
bottom of case). unplug the screen and put it in a safe place. now
remove all the screws on the bottom of the laptop, MAKE SURE YOU TAKE
THE 2 BOLT/NUT/SCREW THINGS OFF THE VGA OUT PORT ON THE BACK! it should
be fairly easy to get the top of the case off now. leaving you with the
mainboard sitting in the bottom of the case. Now flip over your board,
it may take a little maneuvering to get the board out of the case. be
careful not to bend the board too far. be careful not to damage the
buttons on your PCM CIA card slots. You may have to bend the case a bit
to get the VGA ot port out of the case. Now look at the screw locations
on the fans. the screws are on the opposite side of the board. unplug
fans, and swap them out. now put it all back together! NOTE: if you get
several beeps and or blank screen after trying to startup, you probably
didnt discharge the static from your body before touching the RAM and
it could be either burnt out or you may have to take one of the sticks
out and let it sit for awhile.
P.S. if youre replacing the fans because it overheats... its probably
not the fans! its the heatsink which requires taking it apart anyhow,
but where the fans blow through the heatsink lots of crud gets built up
in there and blowing compressed air into it usually does not help. if
you do all this, be careful taking the heatsink off the board! and dont
damage your chip! if you take heatsink off and chip pulls out with it,
youll have to remove chip from heatsink as it is a ZIF socket and dont
forget to replace the silver heat compound on the chip! i found it was
helpful to pull the heatsink off and run it under some hot water, then
dry it with your wifes blowdryer, use some compressed air and q tips to
clean your fans out really nice (dont take them apart, theyll never
work again) and reassemble.. presto! like new!.. any questions?>
give me a holler!

using a multi-purpose duster spray can seems to have solved this for me. i dusted the keyboard and a few other areas(carefully) with a q-tip. i wasn't able to fully open my laptop but i sprayed and q-tipped a little on the inside(i couldn't get to the fan which supposedly gathers the most dust) and when i feel the computer getting too warm,i'll spray the keyboard and the back of the computer and my computer ,which was shutting down **** near constantly, hasn't spontaneously shut down since,and i took out the battery. if your problem is dust,this might be at least a partial solution. if you need to take your laptop apart,there are videos on youtube,although like i say i wasn't able to take my p35-s611 all the way apart without possibly damaging the machine.
The processor is over heating. I have a p-35 s6053 and it used to do the same thing until I fixed it.
Do the fans come on or anything when you first try to turn it on ??????
I'd bet the fans come on strong and then after about 5-60 seconds it just shuts off. let me know if i'm right and I can tell you how to fix it,
The keyboard and the bottom of your laptop are very hot when the laptop is working.
The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).
Solution: If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A70/A75) you have to open the laptop case all the way down.
Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
Clean the fan and the heatsink with compressed air.
I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.
Open the processor area located under your laptop. You can detached and re attached the processor, some sort of lose contact on pins. If same problem occur, your processor may burnt out. pm me firstname.lastname@example.org i will assist you remotely.
If you have to wiggle the power cord it is most likely the DC jack on the motherboard. It is usually the center pin in the the jack that breaks the solder point and the small tension band inside the jack housing weakens.
I had tried propping it up and setting fans to blow on it and that helped some. But then I stumbled on the answer that has kept me problem free ever since: doubling my RAM. My fans no longer run all the time like they used to, it never since had the dreaded "shut-off" problem and it is fast again - like it was out of the box.
