Hotwire does not open


What kind of 'recovery' did you do ?

If you did a 'factory recovery', then you will likely have to re-install the Hotwire software before it will recognize the device.

Car will overheat while at idle


yes the head gaskets leaking on modern aluminum head engines is all to common. never overheat them, if they start to get hot shut it down and find out why, it can of course be the fans and plugged radiators or faulty thermostats but sounds like in your case the head gasket is leaking and combustion gas is entering the cooling system and this causes an overheat

Falcon 4420 scanners needs cmos battery replaced on the pc board. What is the part number the battery and how easy is it to replace?


dont know for sure but these are usually 3032 button style batteries, you can buy them at a local supermaket.
pop out or slide out once youve got the case open.

NB this is a very general solution, open the case first if breaking the warranty doesnt worry you.

I have the same problem my acer extensa 4420


I had a similar problem with my Acer Extensa 4420. After reviewing all the recommended solutions, I decided to open the case to see if I could see a disconnected cable or other easy explanation.

However, when I pulled the heatsink off the CPU and found that the heatsink compound had almost completely dried out. I cleaned the heatsink and applied new compound, then reinstalled the heatsink and put the computer back together.

It works great. Interestingly, this is the same problem that plagued the XBox 360 and the "red rings of death" failure. Just an option that is easier than pulling the entire case apart.

How do I enable bluetooth in my Acer Extensa 4420-5963


Actually Acer use the same laptop case for some of their models, so the acer 4420 doesn´t have built-in bluetooth, you won´t find any driver for the bluetooth cause that reason. I have an extensa 4420-5910, have a bluetooth switch in the case but no bluetooth, if you check at Acer´s web page it say thet some models doesn´t have built-in bluetooth but the switch is in the laptop case... On the other hand, if you install an external bluetooth device, the case switch will be usefull to turn it on and off.

Acer labtop Extensa 4420


The Acer Extensa 4420 is compatible with the bluetooth module for the 5620 or a Dell RD530 module. Do a search on eBay.

Anyway, you'll have to open up your case for this. The connector for the module is just above and to the right of the Optical bay (just next to the speaker connector).

As for how to open the case, the service manual can be found here:
