Digital D2 tablet
Does anyone here by any chance own a D2 1014 Windows 8.1 tablet?
Reason I ask, mine self discharges to less than half in about a month and takes 5 or 6 hours to charge up again. I know the thing is pretty much useless and the company is out of production so its really isn't worth doing anything with. Its about 3 years old and has maybe 100 hours of use (never did like or use it much). I keep it around but don't use it anymore even though it still works well within its limitations. The windows 8 newsgroup is not very active and I don't follow it so decided to post here. Rene |

Eg, Bluetooth drivers may be pinging any devices that the tablet is paired with. You should be able to turn off wi-fi and Bluetooth, see what happens when you turn them off. bluetooth doesn't work that way, especially when the computer itself is off, when nothing would be pinging anything. he said self-discharge, and half in a month is completely normal, especially for an older device. it's surprising it's not more. |

Thanks Wolf, Yes I do have it paired with a Logitech M557 Bluetooth mouse, Seeing I'm not using it anyway I will shut down Bluetooth service and see how it fares over the next month. Rene |

I think there are tow meanings of "off" buried in OP. One, power down. just one. power down is off. Two, turn off the interface (which may or may not turn off the apps). what you're calling turning off the interface, otherwise known as sleep or standby, is not off. since he said self-discharge, it could only be the former. if it was sleeping, the battery would be in use for background tasks (i.e., not self-discharge) and likely dead within weeks. it would actually be amazing if it was only at half capacity in this scenario. Some tablets are more like phones than computers. something that runs windows 8.1 is more like a laptop than a phone, just one without a keyboard. adding touch to what is fundamentally a mouse/keyboard ui does not work well. ipads and android tablets are basically large phones, particularly android, where there are very few tablet native apps. ipads have a *lot* of native apps, making it a different experience than a phone. he said self-discharge, and half in a month is completely normal, especially for an older device. it's surprising it's not more. True. yep. |

You are simply unable to accept that people use words for meanings you don't use them for. i have no problem with that, including your incorrect use of 'turning off the interface' which makes no sense whatsoever. the interface is not turned off nor can it be. i'm going by what he wrote. you're making up ****. he said off, self-discharge, and only 100 hours of use, which is just over 4 days, and then asked why it's at half capacity in a month. that can only mean fully off, not in sleep/standby mode. if it was sleeping, it's not self-discharge. it's actually using power to keep the device alive. Tough ****. Live with it. pot kettle. |

They are chemical and fade in capacity over time no matter how well you maintain them, but fade faster in capacity if you just shove a tablet into a drawer and don't cycle its battery every 4-6 months. From your description, my best guess is it is a Digital2 D2-1014W model. I found an announcement article back in 2014 about that model, so your battery could be over 4 years old. With abuse (no maintenance) and age, that old battery probably can't take much of a charge. https://www.ifixit.com/Guide/Digital...lacement/51594 That shows (for a different D2) how to disassemble to case to get at the battery to replace it. You can find videos at Youtube on generic procedures to open a tablet to replace the battery. The maker didn't really design these devices to have user-servicable batteries. |

The Digital D2-1014b is 3 years old and came direct from the factory as a replacement for one I returned, So the battery is at least 3 years old. I used it a little at first, of and on and did a battery top up charge every month or so, So it did not suffer from neglect or abuse. In my experience lithium batteries don't normally discharge that quickly, In fact I have a couple B&D power drills with lithiums and the company states that the battery should hold their charge for a year if not used. Of course these are probably better quality units than the tablet. In any case its not a real problem as I don't use it very often, My large fingers don't work too well on the touch screen Therefore the Bluetooth mouse and small plug in USB keyboard. It's certainly not worth a battery replacement,and the Company seems to have folded, so replacement batteries may be hard to find Thanks, Rene |

Hi VangardLH I went and dug up the manual and read it over and Yes, You are correct, it says to discharge the battery down to at least 10% and then charge it fully once a month if not used frequently. Thanks for the heads up. By the way Yes, I do a complete shutdown and the screen gives me the "shutting Down" message before I put it away. Rene |

Thanks for the heads up. By the way Yes, I do a complete shutdown and the screen gives me the "shutting Down" message before I put it away. Rene Is the boot time consistent with something coming out of cold storage ? Hibernation would hibernate kernel+session. No power to RAM. Hybrid hibernation keeps the RAM running and keeps kernel+session. Fast Boot is Hibernation with only kernel in the hiberfile. Sleep, on DRAM, keeps power to the RAM, about 1W per stick in auto-refresh. If you have Device Manager devices set for "wake" conditions, that could use power. A NIC with WOL (core powered). A Wifi with WOL. A keyboard or mouse set to wake the computer. "WakeTimers" should be coupled to the RTC (BIOS clock) waking timer (system wakes up and then figures out why it is awake). And that runs off the RTC battery if no other power is available. ******* The battery in my laptop is lithium and lasts for months. Because, I pull the battery, making no shenanigans possible. This also means though, that the RTC battery is being consumed, as the main battery is not there as an alternative. I leave 70-80% charge in the battery, as the longer you leave it at full charge and "max" cell potential, the harder it is on the battery. If a multi-cell pack goes below the min_voltage, the charger won't charge it. If a digital device uses a single cell (like my digital camera), those can be run completely flat, because there is no way for them to get reverse biased. Multicell packs have a min_voltage, on the premise that the healthier cells will cause the weakest cell to have reverse bias applied (effectively minus on the plus terminal). And that can plate out metal. Then making it unsafe to charge the battery again. The 0% charge level is defined in terms of an operational limit that probably has not reverse-biased the weakest cell in the pack. You'd want to do two things. 1) Find out what is using power when it is shut down. 2) Charge to 80% before putting it away again. Batteries aren't usually removable on tablets, so figuring this out for (1) and dealing with it from Device Manager, will be a real technical challenge. Paul |

Thanks for the heads up. that's not needed and will actually *reduce* the life of the battery because it has a fixed number of charge cycles. discharging it for no reason other than to discharge it is a waste. every once in a while, run it down, but do so in normal use and only if the battery indicator is not accurately representing the battery charge. By the way Yes, I do a complete shutdown and the screen gives me the "shutting Down" message before I put it away. in other words, it really is off and not in standby. at least that has been cleared up. |
