Hi all, I'm a novice that has some experience messing around with an Arduino and a bread board and a Pi. Just joined here officially as a 'massager' I bought for the missus about a month and a half ago has failed and I'm unable to return it. The issue is that the massager will not turn off, or at least the lights behind the buttons are always on. I've opened the thing up after a lot prying but I am unable to see where, if anywhere, I can do a hard reset. Any advice would be greatly appreciated as I'd rather not spring for another one at the moment (slightly broke). Let me know if you need any additional info. Thanks in advance

 

Welcome to AAC!

Many modern electronics have "soft" power on/off control. This means that the device is never turned off but enters into a very low power mode. Since the current drawn is very low you should not be too concerned.

 

The only way I know how to do a hard reset would be to disconnect the battery. If you're competent soldering then unsolder one of the two battery leads. Be careful not to let the two battery leads touch. If your skill set is even higher, install a power switch. But like Mr. Chips said - many devices go into low power (sleep) mode. Still, the six LED's being always lit - I'd be concerned about draining the battery, and I'd be bothered by the incessant lights being on.

Doesn't look like there's a BMS (Battery Management System) on that device. It looks cheaply made. I wouldn't have too high a hopes for success other than installing a physical switch.

 

Thanks Mr Chips and Tony! I'll give a bit more info, but I think disconnecting the battery and soldiering it back on is likely to be the only fix on resetting it (or letting it run completely out of juice may work).

So to turn it off or on again you hold the central button for 3 seconds (whether this leads to a low power mode or 'off' I do not know). In its current state it simply never turns off when that button is held, I can feel that the board is slightly overheating due to the length of time it has now been on for. If, on reflection, you agree that soldering is the way forward I'd really appreciate a recommendation for a cheap reliable iron. I'd see it as am investment to be used once in a blue moon and preferable to buying another massager (got to stress cheap though lol).

 

Radio Shack (in the US) or Harbor Freight. Definitely cheap, but good for the "One Off" usage you anticipate.

 

UK based I'm afraid, don't worry though I'll have a look into, it'll be a project

Thanks, I received the kit I purchased yesterday and I've disconnected the battery and resoldered it. Unfortunately the same issue is still there; when charging the central light should flash but instead all three remain solid. These all turn off after an hour or two but the thing still won't turn on - perhaps the battery isn't even charging? Thanks again for the help but I think it's busted
