My friend has had trouble with his P35 for over a year now, it just shuts down on its own. We looked to make sure the fans were running, wich they were. We were wondering if the batteries "he has 2" our no good wouldn't it still stay running on AC power alone?
Even though the vents look clean, you would not believe the amount of dust that collects inside of these laptops! Your best bet is to first, use compressed air and blow it IN where the fan normally blows air out. This should result in a HUGE cloud of dust blowing out of the bottom of your laptop. If you're still having problems after that, you may have to take it apart and manually clean the heatsinks.

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.
Assuming the battery isn't failing or the power supply isn't bad, the laptops cooling system may be clogged with dust causing overheating and sudden shutdown to prevent damage to the CPU. You may be able to blast the dust out with compressed air but the chunks of dust could actually block up the fan, keeping it from spinning, and make things worse! Best solution is disassembly of the laptop to get better access and do a complete cleaning..
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.
yeah if you are planing to do it yourself..it is worth ..I just bought last week a broke one and I payed something under 100$ ..and I changed the motherboard in one that was doing the same..so ...if you think you will use it ..its worth looking on ebay ..or parts to buy what is missing Anyway check the power line on the motherboard ..it may be just something unplugged..or a little part..but if it does not get any power..its just that .. The fact that is charging the battery it means that the power is ok from the charger and the entry on the board...so check the ram memory ..and the power cable of the board...cause if the charging is ok ..and the fan is working ..it may be something like a cable or the switch itself..( in this case the switch board is changeable in a few minutes and has just a plug and 2 screws..
Hi, It certainly could be a case of a bad motherboard but i would check the air vents for dust that may have clogged up, even though the fan may appear to be working fine if there is dust built up inside the unit there is nowhere for the hot air to vent, this will in turn cause the laptop to shut down unexpectedly. Also go into the BIOS and set it to default settings just in case someone has set a shutdown temperature.
Nitrotrike gave you the process you should go thru to solve this problem...
But before doing it, or having someone do it for you,...locate the fan or fans on your laptop, and using a vacumm **** all the dust from them...
If the overheating is been caused by clogged air channels, this action will help your laptop get back to work.
Let me know if it helps
