i am overseas and having issues charging my tablet. if i try to top it up, it starts discharging instead. it does this with different chargers. but it seems to also ch arge sometimes. not sure what is going on. could it be recycling the battery? first dischsrge, then charge?

If its like my stream 7, the only thing that will charge it properly is its own charger. I put a charger doctor on it and for that it will pull over 1 amp fine. Put it on anything else and 140-160mA max, which if the screen is on it will go down. Screen off but powered up will get about 40% in a day at that rate. Worst device ever for charging. Seemed a little better on a car charger compared to generic and iphone wall chargers, but still useless. When I was using it in the car I resorted to a small inverter and the HP wall charger.

Using a proper cable? There are lots of USB micro cables that just have power wires and do nothing with the data wires at all, so devices dont see the shorted pins or other signaling to signal that its a real charger

What's the official charger rated at? HP has such a range of stuff that it wouldn't surprise me that an official charger for product X is not suitable for product Y.

not really. i started that thread because the device was dead. then i got it working by charging from a pc. now i have a different question. i have access to hp charger with correct capacity bit still discharges. my question: is this normal? is it some kind of battery memory refresh, first discharge, then charge? i'm just trying to understand what is happening.

I had a HP Stream 7 and it was very particular to the cord used even more so that the charger, anything over 1500mA will charge it but it only like the supplied cord which was substantially bigger than most other cords. I'm guessing the cord being used is not supplying all the juice form the charger

To conclude this thread, I was able to charge my tablet but I still don't understand how it works. If I leave it on the charger long enough, it charges fully, but if I try to top up a partial charge, it discharges first, then eventually starts charging. I remember this from earlier laptops that did a full discharge/charge cycle to refresh battery memory, but I didn't think that still occurred. The tablet isn't that old and it has a lithium battery in it so not sure why it is doing this. But that seems to be the way it works. If I just leave it on the charger long enough, it eventually does charge. Thanks everyone for thinking with me on this. It is a hassle to encounter these kinds of issues when travelling and the usual tools are out of reach.
