Why won't the device turn on?
Although I press the power button, the Jabra Speak 510 will not show any sign of life. None of the lights turn on, and I cannot connect via Bluetooth. It shows no response to my efforts.
My Jabra evolve 65 was dead after leaving it plugged into the charger over the weekend. I suspect the lithium battery failed, so I pulled the ear cushion piece off (there’s a trick to do this) and got the battery info and ordered a new battery on eBay for $20. March 23rd my new battery will be in and I’ll let you know if it works. I have a desoldering station so the repair should go pretty smoothly.
