Dead HD+: battery problem?

[dakkar-it]

Hello all!
I have a Nook HD+, which has sat unused for about a year. Predictably, it does not turn on.

When I connect it to the power supply (tried with multiple supplies and cables), the LED lights up green; after 2-3 seconds, it turns orange and I can hear the voltage converter whine; after a few more seconds, the LED turns off, and the whine stops.
Pressing the power button just causes the same sequence to repeat. Keeping it pressed has no effect.

I have left it connected to the power supply for several hours, but nothing changed.

I have opened it and unplugged the battery. Connecting the power supply with the battery unplugged results in the LED flashing green/orange. Re-plugged the battery, and I'm back at the situation described at the beginning.

Any suggestion? Apart from "sell it for parts", I mean

hold power button for 10 seconds - it will either turn off or turn on the device.
hit on power button once again - hold it again for 10 seconds.
Hope it helps a bit.

Thanks for the suggestion, but it didn't work.

Regardless of how long I keep the power button pressed, the LED goes through the same sequence: green for 3 seconds, oranngo for 2 seconds, then turns off.

Looks like your battery is dead indeed. You could try to test its voltage using a voltimeter. How many contacts does it have? I think there are battery replacement being sold.

I had problems with my Nook HD+ last week. Though not as extreme as your issue, I left mine unplugged for a few weeks and it died completely. It didn't want to resurrect. Plugging it only showed the battery icon...even after two hours.

Left it on charge for 8 hours while I was off at Uni. Came back to it fully charged. So I would suggest at least leaving it on charge for a half day.

I tried to look into a replacement battery and they are apparently impossible to find...Hummingbird batteries are everywhere on eBay and specialty electronics sites. (I couldn't even find an HD+ battery on Alibaba or cheap Chinese sites.)

I wondered whether the aftermarket 4000mAH Hummingbird battery can be retrofitted. I haven't looked but given a soldering iron and ingenuity, I'm sure it can. A battery is a battery...given the voltage is right and 4000mAH is the HD+'s rating anyway. If you ventured to take that route, let me know how it goes.


(Also, I ended up finding a fix for the battery instantly dropping to 1% problem, which is why I came here to make a thread sharing the news for anyone else who has suffered. Off to do that now )

I had the same issue, I had to leave mine unplugged for like 24 hours and then leave it plugged in for a whole day. I'm afraid to let it turn off now.
