Add bluetooth to the ASUS Eee PC 900
First, a few tips:
All the actions described below entail a complete loss of warranty. Remember that in case of failure only you will be guilty in the breakdown of an expensive device.
For a start, let's take a netbook. Remove all the screws from the bottom of the netbook, the roof of the RAM compartment can not be removed. Next, turn over the netbook, squeeze out the 3 keyboard holders with a flat-head screwdriver, then pull the keyboard, disconnect the keyboard cable by hooking the cable latch on both sides with a screwdriver.
The keyboard can be put aside. In the same way, disable the touchpad loop. Next, unscrew the nine screws, the warranty sticker is most often glued over the fifth screw.
Now the cover can be removed. Carefully - a thermal sleeve is glued on the processor and chipset, it is better to remove the cover gradually, and that is, to tear the processor or chipset from the motherboard.
Now look for the unsoldered connector named “bt_con”, we will work with it. This connector was intended for installation on EEE bluetooth, but apparently something did not work out. Here you can read how to remake a dongle to complete its work (on / off from the BIOS and ALT + F2). Our dongle will just be connected via USB, but inside the Eee PC.
This connector uses a non-soldered USB port. Take any bluetooth dongle, drop a USB connector from it. Decay the dongle as shown. When soldering, close the left and right Data + and Data- pins, or solder the wires to the left pins. I think everything is clear.
There is a possibility that the dongle will not work, since the supply voltage on this connector is 3.3 in., And not 5, as the dongle requires. There are 2 options: use + 5V from another place, or unsolder + 3.3V, bypassing the voltage regulator or a group of diodes on the dongle. I chose the first option, took + 5v from the left USB-connector. There is a possibility of overloading the power supply port, but as far as I know, all ports on the eee pc are powered from one stabilizer. When the flash drive is connected, everything works, USB-hard or scanner did not try to connect.
Next, collect the case in reverse order and use the device.
A permanently connected dongle in standby mode consumes very little power, the battery life is reduced by about 2 minutes.
- Do not hurry!
- Do not use force
- Use a low-power soldering iron, smd parts are very easy to burn
- Use a magnifying glass
- Clean and tin the soldering tip, accurate heating is very important.
