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.

When you turn off a tablet (or phone), there may still be some things
running. 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.

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.

True.

yep.

You are simply unable to accept that people use words for meanings you

I refuse to answer his posts, I just can't sink that low again.
I shut down Bluetooth Wolf, will post results in a month.

bluetooth uses very, very little power, especially when it's not
actively used, and therefore won't make much of a difference.

yep, because you're making it into a semantic argument.

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.

How old is the battery? 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

Make sure it really is powered off. Some netbooks and tablets just go
into very lower power mode but they are still powered. A completely
powered off device won't have any power draw to a still-attached
Bluetooth dongle or to any device on its USB port(s).

You should be /cycling/ the battery at the maintenance intervals, not
just topping it off. Discharge and then charge. Even if the Lion
battery is okay with top offs, some devices own charging logic gets
screwed up unless occasionally it goes through a complete power cycle
which resets or recalibrates the logic. The manual for the D2-961 says:

If the device will not be used for a long period of time, be sure to
discharge and then recharge the battery once a month.

If the device will not be used for a long period of time, be sure to

They do NOT recommend top offs. They recommend a complete charge cycle.

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.

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.

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.

which is why it's called self-discharge, what he originally stated.

if it's in standby, what you're calling low power mode, then it's still
using power, just very little, and therefore *not* self-discharge.

doing that on a monthly basis is very bad advice and reduces the life
of the battery because it has a fixed number of cycles.

if the battery indicator seems out of whack with the battery itself,
*then* it might be worthwhile. otherwise, no.

They do NOT recommend top offs. They recommend a complete charge cycle.

topping off is best for battery life.
