Most likely this is a overheating issue. previous suggestions of getting space between the laptop bottom and the surface it rests on will help but investment in a laptop cooler will be even better. Most laptops have cooling issues. You will notice hot areas near the Alt key and upper left corner of touch pad. Also heat directly under that same location. Warmer to hot air will blow on the fan vent left of the esc key.
Another clue to be sure this is heating problem is does it happen right away or after being on a little while? the long it is on the worse problems get.
Sometimes overheating can be casued by operation in a dirty air environment that builds up dust on the exhaust fan or the vents under the computer. all of these areas need to be clear or airflow to get proper cooling. Never use a vaccume cleaner on these areas while its on and best when the battery is removed as well. static electricity builds on vaccume cleaner hoses and could potentially damage your computer. Clean sufaces with a moist not wet soft cloth not cleaning solutions or achohol as they will damage the suraces of the screen or computer keys and coverings.
Many years as an engineer working on electronic components has taught me to follow these simple guildlines to get a long life from your equipment. The more heat and the longer exposed to heat the shorter the life of components.

Sounds like there is dust where the cpu fan is and its blocking the ventilation path in the laptop. If you can take apart the laptop to expose the fan, I would make sure the fan is free of debris. Clogged CPU fans will cause the laptop to overheat cause the air has nowhere to go.
If you do that and the laptop is still overheating then the motherboard is going bad unless your not using the correct charger for it. If you use a charger that puts out more voltage then whats needed then that could cause the laptop to overheat so you might need a new charger.

There is a small cooling fan in the base of this model. If you look closely at the rectangular vent slots (in the rear left from the front if I remember right) you will see a round area. That's the fan. You should be able to feel some hot air being forced out of the unit there long before it shuts down and if you put your ear close to it you can usually hear the fan if it is working. It is common for these to require replacement. If you search the web using your favorite search engine and look for Aspire 5500 you will probably find a listing for a supplier and a price of several tens of dollars. the fan is equipped with a connector and does not require soldering to replace. Any Acer service depot could also diagnose and replace it if necessary for you, it is a common repair.

SOURCE: Over heating laptop shuts down
What is happening is that the processors thermal shut down safety is activating. Cleaning the fan and vents was a good first step but there is something else that needs to be done in order to make sure the processor is not overheating. First, make sure the fan is running at all times. If it is for the duration you're observing and the laptop is still shutting off, then the problem may lie at the heatsink-processor interface. This is where the heatsink sints on the processor face and has a thin layer of thermal paste between the two. If there has been a breakdown in the thermal paste and it is not doing its job, then you can have a thermal shutdown.
Now, the nice thing about your system is that you can clean the heatsink fan and grills just by taking off the bottom panel. Unplug the wiring harness for the fan and unscrew the heatsink off the processor slot. Clean the surfaces well with alchohol and let dry, then apply a very thin layer of thermal paste to the heatsink, screw it back down on the processor. Now leave this panel access door off while you power the system back up, that way you can easily observe what is going on in this area. Make sure to use good clean compressed air from an pffice supply chain to blow out all vent and compartments. Do not use the sir while the system is powered on just in case some condensation escapes from the can.. Good luck, below is the link to the service manual for that laptop. An illustrated guide of the disassembly starts on page 70.
