Roland EG-101 Groove Keyboard Not turning on

Okay, so this issue has been an ongoing one, and i have no idea what it could be. Essentially, One day, it just refused to turn on. Entirely. The power input was always a bit finicky, and you’d have to put it in the right position for it to work, but it would still turn on. Then one day, it just stopped. Before this, it wouldn’t store presets i had written into the user bank, which leads me to believe the battery might have been bad as well. Im coming here because you all are way more professional than I, and i just need to know if this is a common issue, and if it’s fixable.

This has actually been resolved!
just an issue with a universal adapter and such. I got my EG-101 working again, and i feel great!
