A fairly common problem with laptops is over-heating.
Inside the laptop there is a heat sink and a fan which removes the heat from the processor, which runs very hot. Sometimes the overheating is caused by a failed component, such as a fan, but often it is due to the cooling ducts being clogged with dust, carpet fibre and/or pet hair.
One laptop that seems particularly prone to this is the HP CQ60 as I have seen three in the past few months with over-heating issues. One had a failed fan the others were due to clogging.
Most major manufactures, such as HP, Lenovo, Toshiba etc; post instructions on how to strip down your laptop to gain access to the various components. The complexity varies and for the HP CQ60 the entire system needs to be stripped down to the base board. Instructions for this are at HP and they are very good http://welcome.hp.com/country/us/en/support.html , however, it is not for the faint hearted. If you do undertake this procedure follow the instructions very carefully and keep your screws and parts organised in a methodical order to aid reassembly.
The best method for avoiding this type of problem is to ensure that you use the laptop on a clean dust free surface. Avoid using it on a carpet or other surface that can release fibres. Also keep pets away. All too often I find cat hair on people’s laptop keyboards as the warmth of the system make it a nice cosy place to curl up. The insides of the laptop are very unforgiving of pet hair and the cooling ducts are very slim so clog easily. Make your PC a ‘no pets’ zone!
