Old device not working . Any help would be much appriciated

[Keith781]

I have one old fitbit versa 2 device which i received from my bf . At that time i was not interested in smartwatches but recently i joined the gym and i would like to use my versa 2 but the device is not turning on . It's been in my cupboard for almost a year .

I have tried to my best to make it work again by watching some youtube videos for solution / troubleshooting but worked  . In many article i saw that a restart might help but in my case nothing working .

Hope someone can help with a solution . Thanks

It may be a silly question but have you charged it for a long time, even 24 hours and tried from a PC USB port.

Listen to what happens when you plug it in, the PC should recognize it with a sound, if it then plays a sound like it stopped recognizing it there may be a problem, however if it charges then try a restart the watch with the button

Post back how that goes.

Yes , I have plugged it for more than 24 hours and as you said i plugged it in my pc but pc cannot recognize the device . No sound nothing 😞

Thanks for your suggestion . Is there any other way to make it work ?

Normally when something is plugged into the PC [if its not muted] the PC will recognise a connected device with a noise.

Check your pc volume with something to make sure it is sounding.

Are you sure its mounted in the charger correctly?

@Keith781 I have heard about this through the forum Legend @Rich_Laue, but never experienced it first hand. Seems to make sense though?

Li-ion batteries contain a protection circuit that shields the battery against abuse. This important safeguard also turns the battery off and makes it unusable if over-discharged. Slipping into sleep mode can happen when storing a Li-ion pack in a discharged state for any length of time as self-discharge would gradually deplete the remaining charge. Depending on the manufacturer, the protection circuit of a Li-ion cuts off between 2.2 and 2.9V/cell. (See BU-802b: Elevated Self-discharge)

Some battery chargers and analyzers (including Cadex), feature a wake-up feature or “boost” to reactivate and recharge batteries that have fallen asleep. Without this provision, a charger renders these batteries unserviceable and the packs would be discarded. Boost applies a small charge current to activate the protection circuit and if a correct cell voltage can be reached, the charger starts a normal charge.

@MarkMM 

Interesting point about the sleeping battery. However the PC should still detect a device is present?

Also I saw that a cooling shock, for 24 hours in the freezer and 8 hr thaw, might wake it.

Am wondering if warming the watch above room temperature might also raise the level sufficiently to wake it.

And then charge afterwards.

Do you have any ideas for the case where it might be necessary, though it probably doesn't apply here but its interesting to know.

@Guy_ 

My system volume is up but my pc is not recognizing my fitbit . from last 2 days am trying to fix and the device is not showing any positive response . 

@MarkMM 

I think my device battery is completely dead

Is there any option for me to replace the battery ?

Thank you.
