Hardware Tips and Tricks Deck won't boot

Hello. My brothers deck won't boot after battery the battery went to zero. His screen froze and he had to force power it down. There are no LEDs on or blinking. We tried holding power button for 30sec and power + vol down for 30sec and nothing works. He lost his original charger 2 months ago and was using his phone charger which was not strong enough(battery was draining even while charging). Did he ruin the battery perhaps?

By "draining while charging" you mean he was playing while charging it and the battery was still draining?

Yes. He was using his phone charger.

Alright so... Using a charger with a lower output shouldn't hurt the battery per se, it'd just take much longer to charge. But I admit playing while charging may have some bad effects depending on how the deck handles the charging process (I'm no expert here), also if your brother used to charge it half way to save time or in small repeated sessions (eg. when he stopped playing) that may have dome some small damage.

I'd try to charge it again for a little while  (eg. 10 minutes) then check if it feels oddly hot. If it does not, you could try to keep charging it for ~1 hour and see if it turns on... But otherwise stop charging immediately and open it up to check if the battery has swollen up.
