Hello

Hey I have some suggestions....I have this same kind of computer which is what I am using to write this post.

This kind is the same Acer L100 and I have had it for 17 months and I have never had a problem with it.

I found out the a way to reduce heat problems. It is simply based on the design of the machine and it actually works.

First and foremost this Acer in particular has 2 in built fans on the back.

I found out (using a smoke experiment) that in order to reduce heat build up you have to operate the unit in the vertical position....upright position.

This means you have to use the "stand" which comes with the computer.

I found out that the computer is able to circulate air better if in the standing position. There is a reason...the computer is designed to work this way.

Also ***Very Very important***** you must ensure that the little hatch---or door which covers the front USB and card reader panel must be open at all times.

I found out (and it is the reason Acer perforated or placed a mesh) in this area (front usb panel) is also to help the computer suck in air using its fans.

The computer draws in cold air through the top mesh and the front panel and cools the memory module and the CPU at the same time covering these two critical heat areas in a 3 dimension wind tunnel which then exists the computer as a hot stream of constant air behind the fans which blows outwards.

Covering any of these 2 areas is not only dangerous but will slowly begin a process of component damamge due to heat build up.

I think Acer thought that customers would use the front USB modules when using the computer so assumed that the hatch on the front which covers this panel would always be open but I think that was poor judgement on Acer's behalf.

Acer's ignorance to clearly explain this design feature was a big faliure on their part as well.


This cooling system not only cools the CPU and the memory module but also when the hot air leaves the machine the computer lower section stays cool.

These areas...the top mesh and the one on the front are the main air intake areas of the computer. If you operate the computer in the horizontal mode with the top air intake to the side...the computer will get hot very fast.

If you operate it while in the standing position with the front panel hatch closed....you are covering 1/2 of the computer air intake system and the machine will over heat gradually...and in the long run affect capacitors and other heat sensitive components on the main board.

The smoke experiment I used showed that when the fans are running....the computer pulls or sucks a lot of air through the front panel and the top mesh.

Dust collects on these areas as well and also on the fans and this is a good example of how air flows through this specific computer.

I usually clean the system every two weeks, using compressed air and ensure the fins of the heat sink the mesh on the front panel and the top of the computer are as free of dust as they can be.

While I must confess that I have no idea what Acer was thinking while confining high power and high heat components in a small space, I must say Acer was not clear enough on the operating conditions of this specific model of their computer.

You can only operate this computer in the standing position, with the panel door/hatch on the front part of the computer open at all times.

Room temeprature is also a big issue. Because of the design of this computer, cooler room temperatures are ideal to keep this system in working order.

Sometime back before I had AC, I bought a small external fan and ran it on low and placed the fan directly in front of the computer and there was a big change even in computer speed, stability and response.

Here are the signs of a computer heating up..regardless of make:

1) Computer fans swirling hard and become louder and louder even with few or no programs running

2) Response time decreases and the system will freeze with some programs freezing up...eg windows which will not close or a mouse pointer not moving even when you move the mouse

3) Screen freeze which is not a good sign...it depicts possibility of an instant failure or component damage which is slolwy going on.

4) Unexpected shut downs are a sign that the optimal temperature for normal operation has been surpassed and sometimes the computer will shut down to prevent loss of data or continued damage to components

A computer which shuts down and does not restart is a clear indication that damage has already occured.

My computer has a Foxxconn motherboard and Foxxconn is relaible as well as stable so the main problem here is heat build up but the design of the computer does show that the best way to operate this computer is in the upright postion, clear of any barriers and good air circulation from all sides.

Hope this helps
