G72 charge discharges

My G72 B60US- about 2 yrs old, starts to discharge with the charger plugged in, if I move the plug-in around in the port it starts to charge but then goes back to discharging again. The orange light stops lighting meaning its operating on battery. This seems to happen every few months, then stop acting up for awhile. IT will charge (orange light on) for an hrs trhen goes back to operating on battery.

You need the jack replaced on the motherboard,loosing connection.

BlackBerry PlayBook battery power charge, discharge characteristics, and guidance on extending battery life
KB27705
Overview
The BlackBerry PlayBook may come to a power state where it is unable to power on; a Yellow LED may flash in a sequence of 5 flashes, the BlackBerry PlayBook may boot up to the BlackBerry PlayBook Logo and then power off, may not power on at all.
Discharge behavior under normal use:
Under normal active use, a battery drained to 10% will cause the device to prompt the BlackBerry PlayBook user (notification and audible beep)
Without connecting a charger the device will automatically shut down at 3.53V (0%)
Pressing the power button may allow successful boot, but it will turn off again very quickly
Discharge behavior under no use:
A device left unused but in ‘Stand By’ will warn the BlackBerry PlayBook user at 10% (notification and audible beep)
The warning may not be noticed and the device will go back to ‘Stand By’
Letting the device drain in standby mode drains the battery slower, but more completely
Device will still shut off at 3.53V (0%), but it less likely to successfully boot afterwards
Discharge behavior under 3.53V (0%):
If the device is left to shutoff, the battery will continue to drain below 3.53V due to quiescent current draw from the motherboard and the battery fuel gauge
With the battery between 2.7V-3.53V, pressing the power button causes the LED to flash a pattern (1 solid red light followed by 5 yellow blinks) to indicate low battery (PlayBook Tablet OS version 1.0.5, and above)
Below 2.7V there is no activity, or LED pattern displayed
Charge Behaviour:
The provided charger should be used to charge the device. The optional 12 volt rapid charger is may reduce charging times
to approximately 3 to 4 hrs. Standard Blackberry smartphone chargers, other AC adapter USB chargers, or computer USB ports
are not recommended for the sole purpose of charging the PlayBook as with these methods it may take more that 12 hours to
charge the BlackBerry Playbook.
If the battery voltage is below 3.53V(0%) then the charging behaviour is dependent on the software version. The charging code will limit the charging current to under 400 milliamps, during which time, it may take an hour to reach 3.53 Volts. Once the battery voltage rises past 3.53 volts, then "high-rate" charging will start. If, after charging the Tablet for 4 to 6 hours still does not result in LED activity, attempt to force power on the BlackBerry Playbook by pressing and holding only the Power Button for only 20 seconds.
Prior to BlackBerry Tablet OS 1.0.5:
A BlackBerry PlayBook will never charge while powered off in BlackBerry Tablet OS versions prior to 1.0.5.
The device will show a red light when the charger is connected and then nothing more
Repeated connection of the charger can recover the device in some instances.
Once the battery voltage rises above 3.53V the system will boot and the UI will show charging
Starting in BlackBerry Tablet OS 1.0.5:
The device will show a solid red LED, followed by a solid yellow LED as the device boots into charging mode. This is followed by a yellow pulsating LED indicating charging in progress.
The time span between the red and yellow lights can be as long as 45 seconds as the device boots into charging mode.
Once the yellow LED illuminates, the device can be started, but it is advisable to let it charge for at least 3.5 hours to achieve a sufficient charge.
The device will show a solid green LED once the device is fully charged.
Starting in BlackBerry Tablet OS 2.0.1:
Once the yellow LED begins pulsating indicating charging mode, if the BlackBerry PlayBook is disconnected from the charger, the following graphic will be displayed on the screen, indicating charging is not complete, and to reconnect the power source. The graphic will be displayed for 20 seconds before the BlackBerry® PlayBook powers off if the power source is not reconnected. The same graphic will also be displayed if the BlackBerry PlayBook is turned on and there is not sufficient power to perform the boot process.
If the BlackBerry PlayBook is plugged into a power source, and the power button is pressed to power on the device, the following graphic will be displayed if there is not sufficient power to perform the boot process. If this occurs, the BlackBerry PlayBook should be left plugged in to gain enough charge to boot.
Additional Information
Turning off the BlackBerry PlayBook and using standby mode.
Checking the battery power levelOn the status bar, tap the battery icon. When the battery power level is low, the BlackBerry PlayBook tablet will display a notification.

With the upgrade to PlayBook OS 2.1.0.1032 the following message may be displayed when connecting the Playbook to a PC using the micro-USB cable:
Unable to charge battery with connected source
This message is displayed because the voltage provided is insufficient for charging. The USB voltage is limited to 384mA even if the maximum tolerance is 500mA. The voltage is limited to 384mA by design to avoid violating the USB specification which states USB devices cannot draw more than 500mA from the USB port.

NoKia N8 Static Charge discharge, sweating of the ...

I am currently experiencing a static charge discharge whenever i use the phone in my car and step out. does any one face similar problem? what is the cause and solution?
Also there is extensive sweating of the screen due to humid climatic conditions which i fear could damage the display board and adapter as well as the screen.... any feedback or suggestions...
lastly, am getting a weird error stating memory full when i try to open a call in the log to check duration. the error reads - Memory full, close some applications and try again. But i have no applications running even in the back ground.
Can some one respond please.
Thanks

A quick Google search doesn't bring up anything except you two guys so I would suggest that your unit is faulty and you would be best to get it checked at a Care Centre.
Apart from giving you a "Sting" it is probably not doing the phones electronics much good either.

What is the best charge/discharge regime for the laptop battery?

I have a HP G71 340US laptop with 12 cell battery of 8800 mAh design capacity.
It is clear, that keeping the laptop plugged, and always having 100% charged battery is not the most healthy regime for the battery.
I have found from the web that permanently charging and discharging the battery (like charging form 9% to 100% then back to 9% and so on) is also far not the most healthy regime for the battery.
So my question is: what is the most healthy regime for battery charging/discharging, assuming that the AC power source is always available?
It seems there in so software which can support such regime automatically, as charging cannot be stopped programmable, but maybe there is a software which can report corresponding alerts, informing that it is time to start charging or to start discharging?
This question was solved.

Correct charging/discharging of iPod Shuffle 2nd gen

So there is alot of conflicting info on this topic.
Some forums say to discharge fully once a month. Others say to never let it go below 40%.
So what is the best way to care for the battery?

Use it and plug in to charge when convenient or when changing content... OR when the staus LED starts blinking red. Works for me. My use pattern is several hours daily (sometimes all night if I fall asleep listening...) I generally charge immediately if shuffle was used overnight, otherwise plug in every third day or so.
I've had mine since 10/30/06 and battery performance seems normal (eg 12+hours of operation).

Battery Fully Charging/Discharging

I have new 30gb Touch I hooked up to a USB port on my PC to let it fully charge. It does fully charge but after it falls asleep while still connected to the PC discharges to 10 to 20% within 4-5 hours. I am not even using it so why is it discharging?
Do I have a defective ipod? It is still under 30 days so I still have time to return it unless this is unless this is typical behavior after a full charge or bug with latest firmware?
thx

I hooked it to a different USB and are waiting for it to do it again. In the last 3 hours no discharge but something odd did happen. The Ipod was turned off and all on its own without me doing anything lit up with an all white screen. I went over to it and hit the top button to turn it on to see what it was doing but nothing appeared to be wrong and the battery is still fully charged with a lighting bolt through it.
Maybe if I had left it at this point it would start discharging? Perhaps that all white screen means something?

T42 dies when unplugged yet battery is good, power mgr shows charge/discharge cycle OK

Ok weird problem -
I have a T42 with a "real" IBM battery running XP and latest version of power manager s/w V1.85 .
I can run the battery maint. test cycle and the T42 successfuly (or so it claims) runs the battery down and then charges it back up and reports that it is in good condition.
But when I unplug the 120V charger the laptop immediately shuts off, and will not run from battery. The contacts on the battery and in the laptop seem to be in fine shape. I have tried another battery that works fine in a different T42 but I still have the same problem.
When problem started the BIOS/controller code were downlevel, but I have now updated to the latest:
   BIOS - V3.23
   Embedded controller code V3.04
   Then reset BIOS to default settings
But ... problem remains.
Thanks for any assistance!

No they did not ... although that might have been why it was donated....
We are cramped for space so can still put it to good use, but it would have been nice to be able to actually be portable ... I feared there was no simple answer, replacing the motherboard is more work than I can put into it at the moment. I'll add wireless and we'll leave it "teathered' to a desk ...
Thanks for your help!

Type of charger has effect on battery life?

It seems that my battery has WAY more life when I charge it using the iPhone dock/USB wall plug that came with the phone...instead of other, third-party chargers.
I noticed that, when I put the iPhone in my iHome clock radio to charge overnight, the battery seems to fully charge, but power lasts barely a day with light usage. Same when using my non-apple iPod car charger.
Using the apple charger I was able to use my phone all weekend and barely drained half the battery.
Could this just be the battery coming into its own after several charge/deplete cycles...or does the type of charger make a difference? Are all fully-charged symbols created equal???

The type of charger should not make a difference to the battery capacity. It might be in your charge discharge cycles, you some how calibrated the battery, but as long as the charger supplies the correct voltage and the minimun current, it won't affect battery life at all.

3rd Generation iPod Touch battery won't hold a charge.

My 3rd Generation iPod touch has been very reliable for the past few years, but recently I've been noticing a decrease in its battery life. The battery will now, on a full charge, last about 4 hours on continuous usage. Is this normal? I recall it lasting longer before.
Thanks!

Very likely that the barger is wearing out. That happens with time/charge/discharge cycles. 4 hours is standar for an old iPod like yurs.
Apple will exchange your iPod for a refurbished with a new battery for $79. They do not fix yours.
Apple - iPod Repair price
A third-party place like the following will replace the battery for less. Google for more.
iPhone Repair, Service & Parts: iPod Touch, iPad, MacBook Pro Screens
Replace the battery yourself if you are up to it. Yo can purchase a replacement for about $10

I just bought a new iPod touch 5g and the buttons are all loose and it charges to 100% in like 45 mins.

All the buttons work and stuff; however the volume and sleep/wake buttons don't click or feel tight enough to be new. The home button works fine though, but is loose. I have compared it to my friends and all theirs are tight and work fine. I bought my ipod at best buy. Im not sure they will replace it seeing as how I didn't buy insurance for it. Would the apple store replace it? ALL the buttons work, BUT are not tight. Also the battery charges way too fast (45 min). What should I do. Will it be okay? Help please.

Based on posts here, the loose buttons seem to be normal. Also, other users have report similar "fast" charging. That usually resolve after a number of charge/discharge cycles.
If y are concerned, make an appointment at the Genius Bar of an Apple store.

HP Slatebook x2; Tablet wil not charge, 5sec a battery is shown. After 1 year and 1 month.

Hi,
I have the HP slatebook x2 10-h0000ed, just 1 year and 1 month. (bought and used in the Netherlands)
So 1y1m means, no official warrenty anymore, but a warrenty should not be the life expectancy...
My problem, actually none, until this morning, the X2 was totally switched off and could not startup.
After poweron it was just was showing a battery at 10%, the shutted down?
It seem to me that it has drained itself from almost all power (99%?), and then self shutted down.
Small history of the event;
Yesterday evening I left it at 2x 100% (base+tablet), and disconnected the charger.
The charger led was white (full&ready). So this time I did not leave the charger in the unit, to safe some energy...
While at 2x 100% charged, I powered the unit completely down. Afterwhich I closed the the tablet+base.
Now, this morning the unit did not wake. Normally press the powerbutton for 3-5 seconds or so.
The only thing I saw was a white battery with 10% red level on the black background.
Then after 5 second or so it switched back off by itself.
No fix until so far.
This I tried;
- Disconnected the tablet, and charged only the base. After 1-2 hours? the orange charger led went white. (full)
- Placed the tablet back onto the base, power on. no succes, same battery screen, and back auto off in 5 seconds.
- Disconnected the tablet, and tried to charge only the tablet. After 1-2 hour no succes.
The whole time the charger led was off. Not orange. Not white. Only off. And not charged anyting.
- While disconnected to the base but connected to the charger, I pressed the power.
The same thing happened, but with a twist..
Same battery screen, and back auto off in 5 seconds.
But when the screen + battery image was on, the charger was orange also. But only for thet 5 seconds moment.
This is a mini charging moment ??? And gave me the following idea...
- So I pressed and pressed and pressed the power button for atleast 1 hour uninterrupted, with many pop-ups of
the battery screen. And many temporarily orange charger leds.
With my hope that many times a little charge would revive the poor I-dont-wanne-charge condition.
But no ,also no success.
Power on is still the same battery screen, and back auto off in 5 seconds.
- Placed the none-charged tablet back onto the base.
Power on is still the same battery screen, and back auto off in 5 seconds.
So I read and browsed;
- Many complaints about HP and the battery of this kind of tablet.
The charging sequence problem are in short; Dead on arrival, but most of the time after
changing the tablet at the store it was ok.
So some leaving the factory unchargeable.
- But mine tablet was now 1y1m still up and running ok !
Until the voltage dropped below voltage-X.
- And lower then voltage-X means, by product-hardware, of by prodict-software, (I think)
that the charging-process is blocked and/or shutdown because the voltage is too low.
- In my opinion, when the voltage is too low, it should charge the battery, and not stop and exit and shutdown.
Future actions;
- Now it is saterday, so I have to wait until monday, until I can contact HP (at the Netherlands).
- I will discribe this problem and how this happens.
- I hope that HP is accommodatin and compliant to me with this problem.
- As I say in the beginning, a warranty should not be life expectancy of a product.
- The tablet nor adapter or wires and connectors were mistreated, dropped, bend, scratched, etc. Just normal everyday use. :-)
- I hope HP will give more warrenty then the 1year !
Do you have any ideas ?
I sort of out now.....
regards,
Manuel.

Status update; good.. & and bad..
the good..
The tablet (tablet+keyboard, not adapter) was transported to the HP-centre, for repairs.
From the Netherland to Poland, after a about 1 week it was returned.
The transport service arranged by Hp and Ups, was without any problem.
As requested to not-factory-default or erase otherwise, it was returned OK. All accounts where still fully present.
Repaired; As stated on the repair form in Dutch 'voeding bord vervangen'. Meaning 'power bord replaced'.
So I think something like the charge-pcb (inside the tablet?) was replaced.
Tested; Individual and all joined (tabl+keyb) charging.
While monitoring the power usage with a battery-monitoring-app.
(the 'battery monitor widget', and the system-default widget. always the same results. !!)
Results;
- The normal usage is OK.
- But charging has some issues, see the bad, below.
Also, the 'UpdateEC' popup re-appeared after the repairs.
The message;
UpdateEC
New EC Firmware found!!
Would you lik to update EC firmware?
(I do not know anymore the the version values from and to..)
the bad..
Maybe a new problem, starting from day 1 (after receiving it back).
This is still some preliminairy info, because I am still monitoring this.
The possible new problem; Charging the keyboard-battery !
A strange 'thing' seems to be going on with the keyboard battery.
- When drained to 1%, it charges in 20 minutes to 100% ?? While the table battery charges in 2 hours (120 mins).
- When fully at 100%, is drains much faster then the tablet battery.
- When at 50-90%, or somewhere in the middle, it 'jumps' to 1% ??
I have screenshots of this odd charge/discharge effect.
(screenshots of the 'battery monitor widget'. not the system-default widget, but always same results.)
I will keep monitoring this, and when the problem is a bit more clear, I will probably make a new support-request.
Keep you posted!
regards,
Manuel.

Charging a New 6500 Slide

Handbook suggest around 90 ,but I'm hearing 16 hours to charge a drained (brand new) battery? Is there a problem with the 6500 slide? After an hour of charging I removed the lead and the phone is dead! New phone arrived this morning. Something seems amiss!
Any ideas

A new battery requires a 3 full charge & discharge cycles before it attain it's full power. It takes 2hrs more or less depends on charger & phone model. If you put it on charge for an hour & removing it make the phone dead, its either the battery or the phone power circuitry is defective.
Knowledge not shared is knowledge wasted!
If you find it helpfull, it's not hard to click the STAR..

Model 6102b phone wont turn on/ wont charge proble...

so ive had this phone (6102b) for a few years and its been working fine. a few months ago it turned off and wouldnt charge. Randomly a month later it just started working again. About a week ago the phone died again. When i put the charger in to charge it, I can see on the front screen that it changes colors very slightly, so i can see power is getting through the battery. Anyone know why its not charging though/ why the charging screen won't come up?

since you have had it for a couple of years, the battery may be nearly past its lifetime. batteries only can cope with a limited number of charges/discharges before they go, so i would suggest that you purchase a new battery. another possibility is that the phone may be damaged slightly, but i don't think this would be the problem (as this happened with an Alcatel 756 i had, a month after purchasing it the same thing that you describe happened to me, then i left it alone for a month and then it started working again and hasn't broken down since). but i really doubt this is the scenario you are in, i really think you just need a replacement battery.
hope this helps

Had Power Adapter replaced, battery icon not showing charge

Hello, hoping you guys can help me out. Recently, my power adapter had burned out (wouldn't show charge/light up at all). I've had it replaced as of today and is working fine (Whoo!), but now a new problem's come up.
I admit I used my battery to it's limit while waiting for the new adapter, and while the light on the adapter is green, the battery icon on my screen is showing 0%. Pressing the button on the battery only gives me one green light.

Re-calibrating the battery is typically done with a new battery, where you charge it all the way up, then run it all the way down a couple of times. This calibrates the battery's internal electronics to the actual capacity of the battery. Not a concern here.
Looking at your battery stats, is your battery fairly new? It is showing 56 charge/discharge cycles, does that sound about right? Reason for asking is, if the battery is old, like maybe the original battery that came with the system, sometimes a dying lithium battery throws up screwy stats. If it is an older battery, that may be why it's not charging ... it's dead. However, if it is a newer battery ....
There's only 4 components to the charging circuit - power adapter, dc-in card, battery, and logic board. You have a new power adapter, and the system is seeing the 65 watt power adapter, so the power adapter and dc-in card appear to be OK. That leaves either a battery issue or a logic board issue. Do you have another battery you can swap in, or a friend with the same model PowerBook, or an Apple store nearby? If you swap another battery in, and it starts charging, and the current batter is an older one, then replace the battery. I used this one on mine, and others have had good things to say about it: http://eshop.macsales.com/shop/powerbook/battery/g4-15inch-aluminum/ . I would stay away from batteries sold on ebay, as there have been a number of people very disappointed with the lack of quality in the battery they bought.
If another battery won't charge, that would point to a logic board issue. We just had that on one of our PowerBooks, where it would charge, and it wasn't a power adapter, dc-in, or battery problem. The Apple store sent it off to the Apple Depot, for around $350, and they replaced the logic board as well as the battery. If they do more work, like replacing a dented case, the price goes up. If the Apple store replaces the logic board in the store, it costs around $750 or more.

Powerbook G4 battery wont fully charge

My computer has been plugged in for at least a week, and its not fully powered. It stops at 84 percent. and when i click show>time, it always says still calculating
help would be much appreciated

Welcome to the Apple discussions.
How many cycles do you have on your battery, and what is it's current capacity? If it doesn't show up in your system profiler under power, go to http://www.versiontracker.com/macosx and download a battery status program.
Lithium battery life is not measured by time, rather by the number of charge/discharge cycles. Apple says a properly maintained battery should retain 80% charge after 300 charge/discharge cycles. If you haven't already, this Apple article discusses battery maintenance: http://www.apple.com/batteries/notebooks.html
You might try resetting your power management unit (PMU) which may help, follow directions at http://docs.info.apple.com/article.html?artnum=14449
