Xbox Elite Controller disconnects when using official battery pack
First of all need to apologize for my English, its not my native language. I will try to describe the situation as I can in every detail.
Probably the issue is completely my fault. Yesterday tried to clean sticky left trigger that annoyed me for ages, used alcohol. Luckily the trigger problem was resolved in seconds, but after a short while the main problem appeared.
After cleaning I put official battery pack back and Xbox button started randomly flashing, next I removed the battery pack and waited about 30 mins in hopes that alcohol remains fully dry. Unfortunately after the controller found the console and paired it turned off making strange buzzing noise. I waited a bit more and even tried to use drier, but these pitiful attempts have led nowhere.
Later I removed the battery pack and connected controller directly to the console by cable and found out that many buttons were pressed by themselves, and the sticks behaved the same. At that moment I decided to disassemble the controller and clean it. Managed to did it without further unfortunate consequences, tried to clean it as good as I can and then assembled the controller again. Cleaning solved the problems with buttons and sticks, but the main issue remained, the controller disconnects when using official battery pack right after connecting to Xbox or PC (yes, i tried on PC too).
Strange but the controller works perfectly by cable OR with regular batteries, as soon as I put official battery pack it disconnects after pairing in 4-5 seconds.
I even tried to reflow the solder of battery connectors. This action as well did nothing. The controller works and fully operational, the only problem is disconnect with official battery pack.
Before you suggest that the problem lies in the official battery pack… I put it in another controller to test and it works perfectly.
I will attach photos of both motherboards in case some of you can spot the problem immediately.
I completely lost at this point and don’t know what to do.
