Is laptop cooler is really needed and can reduce the temperature of a laptop? Here are the results from the simple test I have done.

I use the laptop cooler Vitac, which was priced at RM50 when I bought it at Lowyat. The flow of air from the cooler is quite nice and the fan of the cooler is perfectly under the cooling hole of my laptop.

This article is not about on how to resolve the problem of unable to turn on bluetooth on Acer laptops. Basically, most laptops from Acer use same casing design for different models. This casing includes the Bluetooth switch to turn on the Bluetooth.

Having this switch does not mean that your laptop has bluetooth hardware. The Bluetooth driver and software can also be installed on laptops without Bluetooth hardware, so having the Bluetooth software installed does not mean the laptop has the hardware for Bluetooth.
