Help my computer keeps over heating!

[abbee88]

I have a Toshiba L655-s5150 and it will work for 20 minutes or so and then over heat and say system over heating. Turn off and return for service. I don't think that my warranty will cover any expenses. Do I just need a new battery or is there anything I can do to stop this from happening. I feel it get really hot and it has actually burned my leg! Please help!

Hey abbee this might help you out your overheating is more than likely crud in the inner side of the "radiator" and the CPU compound to have gone hard and the GPU compound "rubbery" I don't know what crap they put on that but I always use Arctic Sliver after a thorough clean with the Arctic kit.

Taking apart Toshiba laptops and notebooks. DIY guides. Disassembly instructions.

How to disassemble Toshiba Satellite C655 or C650 laptop >> Page 1.

Make sure you read the first entry thoroughly as the ribbon cables are very easily damaged. Plus easy to get out and very hard to replace back in.
One more tip if the bottom panel does not lift off easily DO NOT force it you will have missed a screw usually toward the centre of the bottom panel or under the keypad.

Do the disassembly on a large white spread out towel it stop s the screws from bouncing of the top and you losing them.

Before disassembly check the radiator by shining a very bright light into the outer vent you should see it quite clearly through the fan aperture.

Thank you so much. I will try this and hope it helps! I have had the laptop for 3 years now, so the warranty is no good.

Yes abee I have had a few Toshiba's in from friends and a couple of my own and the first an old A200 the HDD let go two weeks after the warranty ran out so I bought the second (Sat L550 Pro) with extra warranty but even so I had no end of trouble with it.
The brand in my mind has gone down the gurgler as far as quality goes - they used to be the best.

I have now stuck in SSD's and more RAM plus an OEM and mate the difference is just worlds apart you don't realise how much crap that Toshiba stuff takes up.

Up to you but an SSD and an external for data would make your life so much different

If you get into strife just post or message me

Depends on what those temps are Jacee if the CPU compound is cactus or the rad is blocked then I don't think any amount of outside is going to make much difference.

But that's just my opinion for what it's worth.

See if the following helps, just copy-pasted from a previous post of mine:

Most of the heat is generated by your CPU as compared to GPU and HDD/SSD. Lots of heat is generated when you run a CPU/GPU intensive application like a game, for instance. To prevent this overheating follow this:

1. Go to control panel -- Power options
2. Click 'Change plan settings' link present against the selected power plan.
3. Now click on 'Advanced power settings'.
4. Now expand 'Processor power management' and select 'Maximum processor state'.
5. Now select a lower-than-100 value such as 95.
6. Click OK. Done.

Doing the above underclocks the CPU depending upon the value chosen.

In my case, I chose the value as 99 on Core i5 480M. This just disabled turbo boost and the cpu ran at a maximum of stock clock speed.

The performance difference is NOT noticeable at all (for lower than 80 value, it might be noticeable).

Choosing the value as 99 reduced my cpu's temperature by around 20 deg C (that's a big big difference) and totally cured overheating.

If you're still wondering about the performance dip (which you shouldn't at all), then create a seperate power plan and apply the above settings to that plan. Now you can switch between normal power plan and this newly created optimized plan when you want. Just select the optimized plan from the taskbar before starting a cpu intensive application such as a game.

You may try using a lower value like 80-85, but there might be some noticeable performance dip since you have an older pentium processor.

Yes nilank ok but it seems to me that there is more and more info coming on board that is going to confuse abee as to what to do.

Now the fact that he says that the laptop is getting hot on the outside smacks of some inner parts going out of their limits. So abee can you please post back what the temps are for the CPU and motherboard use Speccy for that mate .

Once they are known then t will be a lot clearer as to what is going on at the moment there is just too much info on what it could be and what it possibly is.

Speccy - Download < download from piriform

In the meantime I will look for the specs on that CPU and have some idea of what your temps are in relation to normal.
