Often enough a good cleaning is all that's needed, but understand besides dust bunnies, there is really impacted dirt on innards. This in turn doesn't usually go away and only a direct cleaning will do and you have to see it and "brush or wipe it off". A basic canned air treatment will do fine for most. I further suggest that you think of using a laptop fan pad to better provide cooling. Some laptops are more prone to heat stress and/or have already succumbed to heat damage, so if this all reoccurs soon, think along those lines.
My Gateway Laptop keeps shutting off on me. It happens when I am on the internet and activly using the computer. Based on what I have been reading it has to do with the computer getting too hot. If this is the case how do I address this issue?
Are there other issues that could be creating the problem of the computer shutting off?
