Acer Aspire 3820TG Notebook Win7 Drivers, Applications, Manuals

After writing to EC, the brightness changes either on hardware level or via device drivers, that themselves read the values from EC and talk to other hardware to change the brightness level. Typically, what is referred to Embedded Controller is a micro-controller that has 0xxFF in hexadecimal user-accessible bytes.


Most of those bytes have a meaning and are responsible for controlling the hardware or providing information. For example, on TG the byte at [0x93] stores the state of the CPU fan and byte at [0x94] stores the fan speed. In nutshell, Acer Aspire 3820T Notebook Broadcom WLAN Controller stores numbers, and by reading and writing to EC, we can get information about the system and make changes to the state of computer hardware such as fan control. Why would you want to read and write to Embedded Controller EC? The simple answer is: Writing to EC allows you to control hardware that cannot be controlled by other means in the way you want.

For example, someone figures out how to control the fan and shares his findings, then a programmer writes a small utility to control the fan by reading and writing to EC.

This program is then published on the Web and ordinary users can install and use this program to control the fan on their computers. There are many examples of such programs. Some of them are: It is not uncommon for programmers to take existing fan control tools and port them to Acer Aspire 3820T Notebook Broadcom WLAN system, or edit them to enable fan control on their hardware. If you plan on developing your own tool, then I highly suggest reusing existing solutions and if you end up writing your own tool, then make the source code available for others to modify. It is very important to note that it is rare to find two laptops that use Embedded Controller in the same way. So don't be surprised if changing some value in EC works on one laptop, but doesn't work on yours.

How can you read and write to the Embedded Controller EC? There are many tools you can use to read and write to EC.

There may be other tools for both Windows and Linux, but the author did not look for any alternatives as both of those two tools worked well on his computer. So how do you figure out what the values in EC stand for? Before you start figuring out what you can do with EC on your machine, you should first spend the time and search the web to make sure there is no existing solution to your problem.

So you search for tweaks on T, and find that there is an existing fan control tool that works with your T laptop. Another good idea would be to search for all models from your laptop manufacturer and see if any existing tools or EC methods work on your model. It could significantly narrow down your search if you know approximately what you are looking for and how it could look like.

This will significantly cut down Acer Aspire 3820T Notebook Broadcom WLAN the time it takes you to find what you are looking for. If you can't find any existing solutions, then you could try figuring it out on your own. For example, you notice that in byte located at [0x72] bit 1 changed from 1 to 0 when WiFi is turned off via a hotkey. You can then try changing [0x72] bit 1 back to 1 to see if that turns the WiFi back on.

You should be careful and have some sort of a system to make sure you don't check the same byte twice. You can make changes to EC and see if anything changed in your system as a result. For simplicity, if the byte you change changes itself back to the original value, then you can Acer Aspire 3820T Notebook Broadcom WLAN of it as "read-only" byte.

Changing this value will make no difference in the Acer Aspire 3820T Notebook Broadcom WLAN, and bit will revert back to its old value automatically. Another more "scientific" approach is to examine the code that writes to EC. The extracted table is in compiled AML byte code, and will need to be decompiled to get the original source code.
