Causes of Laptop Overheating Physical Causes of Laptop Overheating
For a properly designed laptop, the most common cause of overheating is blocked air vents. When dust blocks the fans and air vents designed to cool your laptop, overheating results. (In some cases, blocked vents and poor design are related, as some designs are excessively prone to becoming clogged with dust).
Software Causes of Laptop Overheating
In other cases, laptops overheat because the software designed to protect the laptop – specifically by controlling the operation of cooling fans – does not work properly. In some cases, this is due to problems in the computer’s BIOS, and can be cured by upgrading to the most recent BIOS. In other cases, upgrading or changing the computer’s operating system can cause this software to not function.
If, for example, you have upgraded from Windows ME to Windows XP, the system software designed to operate the fans may no longer work properly. (What’s worse, the laptop manufacturer may refuse to provide support in this instance, on the grounds that you changed the operating system and so are no longer operating the system as it was designed to operate.) In other cases, replacing Windows with Linux has led to this problem if the proper Linux utilities to control laptop cooling were not installed.
Design Causes of Laptop Overheating
In a distressing number of cases, laptop overheating results from poor design by the notebook manufacturers. Some manufacturers cram desktop CPUs into laptop configurations, and do not adequately provide for releasing the heat that these desktop CPUs create. Others simply have failed to provide ventilation and cooling systems appropriate for today’s CPU and video chips, which hold many more transistors than in the past and so generate more heat.
Several class actions have been filed against laptop manufacturers due to overheating laptops, including Toshiba and Dell. Previous class actions have led to settlements under which compensation was awarded to owners of overheating laptops who ran up repair bills trying to get the problem fixed. More class actions related to overheating laptop and notebook computers are reportedly under consideration.check here for more information http://www.fonerbooks.com/lap_fan.htm

    you can Remove the fan/heatsink assembly. Clean the vanes, clean the old thermal grease off, replace the thermal grease with new grease and use comprssed air to blow if clogged by dust may be during storage but be careful not to void the warranty seal if its still under warranty should incase if its the design cause of over heating if possible you can Add the following to your /etc/modules:

Your Model of Aspire has a different battery release method, see attached pic on how to do it. This is a pic from your User Manual, you can download it from here Download Acer Aspire E1 572

. I suspect that the information you have been given regarding battery removal and passwords refers to removing the cmos battery as in a PC in the hope that it will clear Bios activated passwords.

Bluetooth & sound


Generally, connecting phones via bluetooth to a laptop just allows for file transfer between the two devices. It is not to input sound from the phone through the speakers of the laptop. You would need a bluetooth audio device for that such as bluetooth speakers or headphones

How do i reset my computer to an earlier date?


Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!
