Hi, I’m having trouble fixing my tab s 8.4 i’ve already searched many solutions/answer here and also in other forums but non of it can fix it. scenario: disconnected back battery for some minutes turn it on again - nothing happen uses diferent button combinations - nothing happen lastly when i charged the device it sometimes turned on and display the battery sign and goes to 0% and just turned off. the last charge i did is using my LG quickcharge charger and the charger gets really hot and also the port of the tablet. any fix to this or is this a hardware issue?
It’s a hardware issue, now this can be caused by a number of things:
- Charging port physically damaged: Visually inspect the port with a flashlight and look for any corroded, bent, missing or bridged pins that are touching each other. This includes the plastic part under the pins being worn too.
- Clogged up charging port: If this is the case, the charging cable may not plug in fully meaning you need to clean the charging port with something like a toothpick carefully.
- Liquid damage / corrosion behind the charging port pins: To confirm this you need to open up the device and check the charging port daughter board for any white marks / corrosion. Sometimes you can fix this with 99% isopropyl alcohol brushing and/or resoldering else you need to replace the charger port.
- Loose battery connector due to bad solder joints causing a bad connection between the battery connector and the logic board. This can be fixed by resoldering the battery connector to the board. I recommend taking the device to reputable repair shop that does soldering to fix this for you.
- Lastly, but least likely is the battery being faulty: This can be the case but it happens rarely.
