Laptop burnt my leg!

Does nobody contort themself to avoid the air flow bits being covered - or is that just me?

My Toshiba laptop has the following written on the bottom: "PC base can become hot. Avoid prolonged contact to prevent heat injury to skin."

Yes, it says that on the bottom of my Toshiba laptop too. Suggest OP checks the bottom of hers before pursuing with Toshiba.

The cooling fan is for the CPU to stop it overheating and breaking. It has nothing to do with the battery, which is the where any heat a user would feel would be coming from.

I think you have a faulty battery.

All our batteries are cool and the heat is coming from another part of our laptops.

Never had a hot battery, heat always around the CPU area.

Especially on cheap, large laptops with short battery lives, the sort bought be people who want them as a replacement for a desktop. They use what are in essence desktop components and rely on pulling enough air through the enclosure to keep them cool, plus providing a thermal bridge between the processor heat sink and the back of the case.

CPUs that dissipate upwards of 30W are not uncommon in desktop replacement machines, because the budget doesn't run to the lower power consumption devices and the workload (gaming, in particular) needs desktop-class processors anyway. If your laptop cost less than 500 quid and still manages to run first-person shooters fast enough to keep your teenage son happy, the chances are that the processor is going to run very hot.

CPUs and dedicated graphics cards cause the majority of heat in laptops which is exacerbated by the fact that laptops are forced to condense parts closer together which restricts airflow and cooling systems that can easily be implemented in desktops cannot be implemented easily in laptops. Laptops, like desktops, can also be prone to dust build up but unlike desktops where it's usually just a matter of sliding off a side panel and cleaning dust out, laptops often require complicated disassembly to get at the majority of the dust, especially as unlike desktops, there is no standardised internal layout for components.

It is sensible not to use a laptop on the lap, nor should they be left in contact with fabrics, as fibres from clothing, sofas, beds etc. contribute to dust build up in the laptop and affect how heat is dispersed from the laptop. In some extreme, but thankfully rare cases, this poses a fire hazard. The majority of laptops have some vents on the bottom of the machine which are also blocked when placed on the lap or on fabrics. Hard surfaces are better suited to laptops, as the little "feet" on the bottom of most laptops will provide a slight amount of elevation for dissipating heat. However, best of all is a proper laptop tray, many of which are lightweight and comfortable to use on the lap and will generally have a hard mesh that not only supports the laptop but allows better dispersal of heat and better intake of cool air should an intake fan be placed on the bottom (sometimes the case, not always).

Some of the fancier laptop trays also feature their own fans which are usually low power (drawing power from a laptop's USB port) but provide a slight amount of airflow and circulation. The better ones, from manufacturers such as Coolermaster, also feature dust guards on the fans to help block unnecessary dust reaching the machine. Coolermaster also make a series of modular laptop trays where the fans can be positioned by the user in order to best take advantage of any underside venting and intake fans.

Having had problems with my laptop, I bought a Targus one and it has solved the problem. My computer shut down everytime I watched Coronation Street. It's made a huge difference.

And that's a bad thing?;)

:rotfl::rotfl::rotfl:

It was terrible - the fact it shut down, not the programe, before you say anything.
