Hi,
Apologies in advance for the long post.
I've been trying to find somewhere to ask this question where people might be able to help, and after reading through some of your forums this site looks like a good bet.
As a hobby, I repair games consoles and I've got a mark two Xbox One controller that I've been trying to repair after someone threw it.
I won't go into huge detail unless asked for specifics, but the controller contains two pcbs linked by a pair of connectors, one of which is particularly prone to damage from impacts or just general usage (I'd call it a pretty huge design flaw personally).
This controller has suffered from several damaged traces in one of these connectors due to being thrown which has resulted in non-functioning buttons, I've fixed this and on test it works perfectly IF used via a USB cable.
The problem arises when you try to run it from batteries. It flashes twice and powers off, as if the batteries are empty and even when run via USB it shows the batteries as empty and won't run the rumble motors as a result.
As far as I can figure this has to be one of three things:
1. However the controller determines the battery level (a transistor maybe? This is what I really don't understand) is stuck / broken so it permanently reads empty.
2. There is further damage to a trace at the connector, but I cannot find any at the moment.
3. The controllers control chip has a fault and there's nothing I can do about it.
Unfortunately there are no schematics I can find for these controllers and as I said I don't understand how batter charging circuits really work and read levels. I could provide photos if that'd be of use.
Can anyone help me shed some light on this please?
Cheers,
Dave.
