T510 Battery Power Low.. Plug in power issues

I move from location to another location disconnect the power and then reconnect the power on laptop T510.
After a few hours’ work I get the message “Battery Power Low.. Plug in power”
The power adapter was plugged in from the start… All I do us remove the power connector and re-attached.. Then all is OK..
The battery icon in lower screen shows 97% available (plugged in, not charging)
Finding this scarey.. If I have a bettery or power failure at customer remote site.. I'm a telecom field engineer...

That's no problem at all PKcool.
Here are the drivers you will need to install on your computer:
Power Manager for Windows 7:

ThinkPad Power Manager Patch module for Windows 7:
http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS018811
I would suggest going into your Programs and features and uninstalling the Power Manager from your computer, same goes for the drivers associated with it in device manager.
Once uninstalled I would then download the drivers from the links above. This will give your computer a fresh install of these drivers.
Please let me know of the progress.
Hope this helps,
Alex

Battery Lost 3% Overnight After Power It Off

I have a MacBook Air that was bought brand new in August 2013. Couple months ago, I noticed that the battery lost 3% of charge each day after I powered it off. I powered it off at the end of the day around 6pm and the next morning when I powered it up again at ~9am, I found that the battery lost 3% of charge. I went to the Gensis bar to have it check out, the tech there found no problem after running the test and they suggested me to re-calibrate the battery by draining the battery all the way to 0% and then fully charged it to 100%. I tried it couple times but it is of no help.
Any idea how to fix it or diagnosis the problem?
Thanks,
Ken

At this rate it will have about 60 cycles in a year. When does it get near replacement time for the battery?
Cycles are rather meaningless other than in the case of old age degradation of the battery which is utterly 100% unavoidable.
Concentrate on use/abuse of the battery, ... counting cycles serves very little purpose.
If you take care of the former, the later becomes irrelevant and ultimately unavoidable.
https://discussions.apple.com/docs/DOC-6342
Proper understanding of a battery charge cycle
A charge cycle means using all of the battery’s power, whether that is at once, or over several shorter battery discharges and recharges.
Two examples for clarification:
As a first example, where one fully charged battery is discharged down to 10%, then fully recharged, then using 10% of that full charge, this counts as 1 cycle since the total of both discharges is 100% of a full charge of use.
In the second example, where one fully charged battery is discharged down to 40%, then fully recharged, then using 40% of that full charge, this also counts as 1 cycle since the total of both discharges is 100% of a full charge of use.
While both examples are that of a single charge cycle, the first example is more aggressive against the lithium battery chemistry than is the second example. In short, collective overall gentle shallow or mid-range draining of your lithium battery is a better use condition than is the first example of deep-draining of the battery. While both are quantitatively identical as a single charging cycle, they are wholly different qualitatively on the battery chemistry, which is directly related to its ultimate longevity and health.
In short, it is the near and mid-term life of the battery as relates to its proper care (or lack thereof) that is to be looked after.
Priorities in order of decreasing importance for battery care are:
1. Avoiding deep discharges of the battery.
2. Avoiding having your battery constantly on charge or on charge and in sleep mode.
3. When playing graphics intense games, use your notebook plugged in when possible.
4. Reduction of battery cycles by plugging into power when on the go, or when accessible.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is vitally important on the wear and tear on your Macbook’s battery, much more so than is the counting of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will greatly hasten the lowering of maximum battery capacity.
Understand that a charge cycle is a general parameter of use, but is not directly related to the short-term or mid-term abuse of the battery, which can rapidly hasten a shorter lifespan, regardless of what the actual cycle count on the battery indicates.
Proper considerations for near-term care of the battery is of utmost importance. Abuse of the battery is entirely avoidable, long-term eventual old age deterioration of the battery is entirely unavoidable.
Apples SMC and software mitigates MUCH potential for battery misuse /abuse, ....however it is still readily possible to abuse the battery.

Have you left the iPad charging for a couple of hours or so to be sure?

How can I turn off battery charging when plugged in to power on a plane?

Hi,
is there an app that can turn off battery charging while plugged in?
I regularly fly from Australia to Europe (22 hours on the plane!) but the power outlet usually stalls when draining too much power
(e.g. 85 Watts for my Macbook Pro battery).
Any solutions available?
I used to just take out the battery, however, that is not possible anymore on the Macbook Pro.
Thanks for your help.
Christoph

But why turn off battery charging, makes no sense in this case. You either run off the battery or plug it in and run off the battery while it is charging.
The power draw won't change appreciably.
My bad power consumption will change
It would seem the best strategy would be to get on with a fully charged battery plug in the laptop and let it trickle charge as you use it. Given the length of the flight this should give you the longest use with the minimum amount of draw from the seat outlet.

Can I keep the power cord plugged in when battery reaches 100%l?

Hello,
I'm assuming the battery stops recharging when it reaches 100%, right? In other words I can keep the power chord plugged in without any risk of "overcharging". Correct?
Thanks.

Helpful, thanks. FYI, 2 Apple agents at Mac support have advised otherwise (said I have to remove the cord).
How bizarre....I have a 2.5 year old MacBook that gets great battery life (~4hrs) and begs to differ. Anyway, Thanks for the Star!

Powerbook G4 won't charge battery or run with power adapter plugged in.

My Titanium Powerbook G4 will not charge the battery or run with the power adapter plugged in. When plugged in the power adapter doesn't change to amber showing its charging. Instead it has a green light that flashes off and on. I thought it was a defective power adapter but when its plugged in to another powerbook its seems to be working properly. I reset the PMU but that didn't help. I have been unable to find anything that would tell me what a flashing green means.
Powerbook Titanium G4 Mac OS X (10.3.9)

Hi, Marshall. With no power being supplied to the Mac for several months, not only has your main battery gone flat (and may never again be able to take a charge), but your internal backup battery has also gone flat. A Tibook with a dead backup battery generally will not start up at all, even with AC power connected.
Try this: remove the main battery and leave the AC power adapter connected overnight in an attempt to recharge the backup battery. If the Powerbook won't start in the morning under AC power, the backup battery is shot, has lost the ability to be charged, and must be replaced.
If the PB starts up in the morning on AC power, set the date and time correctly, shut the computer down, insert the main battery, and allow 48 hours with AC power connected in an attempt to charge the main battery. Then disconnect the AC adapter and try to start up under battery power. If that doesn't work, and no lights or only one flashing light appear when you press the power-indicator button on the battery, you'll have to replace the main battery.

Why is my battery % getting lower even when my power adapter is connected

Hi!
Got my new macbook pro few months back. At first I loaded battery to full and totally empty about 3 times. Currently it has 14 cycle counts. I mainly use my computer with power adapter plugged in. When I charge it to 100% then afther time passes it goes 99%, 98%, 97%... but all this time my power adapter is plugged in. When I unplug it and run it on battery and then plug power adapter in again and when it reached 100% then again afther time passes and with power adapter still plugged in, it starts to go from 100% to 99..98..97%. At this time I usually unplug it, run it on battery and then again plug it in. Whatever the % when power adapter is plugged in (100%, 99%, 98%, 97%), Time view shows always "charged". I haven't let it drop more that 97% before I unplug it, run it on battery for a while and then plug it in again.
If I let it drop more than 97% (although power adapter is plugged in) will it eventually drop to 0% and time view still shows "charged" ?
All this time I have about 3 word documents open that I'm working on, 1 pdf document open and safari with different dictionaries all at once and time afther time I shearch the internet.
Is that normal with these applications running or not?
Why is that?
My older computer, macbook, when it's power adapter was plugged in, it always showed 100%.
Any word of advice?

That is normal behavior. The power will drop several percent before the charge function kicks in. If you leave it on power you'll notice it start to charge somewhere around 96% maybe 95%.
You can just leave it plugged in and it'll take care of itself.

Captfred

IBook won't power on... power management issues?

Hey everyone,
_MY SYSTEM_
I've got a 12" iBook G4 (1.33 GHz) running 10.4.10 that's about a year and a half old. It's been a great computer for me, and I've used it on an almost daily basis since I first got it. Its experienced a few power-related quirks within the last month or so, however. I can't think of any event that would've caused them.
_THE SYMPTOMS_
I first started noticing that OS X sometimes displayed the low battery warning at odd times or not at all. I didn't think much of it... figured it could be my power adapter coming unplugged or something. Then I started noticing decreased battery life, but I chalked it up to the effect of fairly heavy use and lots of charge cycles. I continued to feel like my power adapter was getting progressively more finicky... it started requiring much closer contact with my iBook than it used to, but since it's a friction fit, I figured the contact was just getting looser.
_CURRENT STATUS_
When I turned the computer on this morning and plugged in the charger the status bar icon didn't seem to recognize it as attached to the adapter. The colored ring around the connection point would go green when connected, but never turn amber. So I used it today until it went to sleep on me. Tried plugging the adapter in, but the same issue existed... the ring would turn green but never amber and the iBook wouldn't actually charge.
TROUBLESHOOTING
I first tried another adapter with no luck. I was able to use the power button to shut my iBook down with the intent to reset the power management unit on startup. That key combo didn't even produce a startup, it just killed the adapter's indicator light for a brief moment. Unfortunately the battery seemed too depleted to start the computer back up. I tried zapping the pram, and that got me to the login screen before the computer recognized it was low on power and went back to sleep.
SUMMARY
As far as I can tell, the computer isn't recognizing either adapter when one is attached. The battery doesn't seem to be the issue. My iBook is completely unresponsive without the battery (only on AC power), and doesn't charge the battery when both are connected. Anyone have suggestions for me before I make the trek to the nearest Apple store?
Thanks,
Matt

If the power adapter seems looser when you plug it in, you might have a problem with your DC In Board. This is what the power adapter plugs into, and it can become damaged.
You can go to http://www.ifixit.com/ and look up the DC In Board for your iBook and see what it might take to fix it yourself. If you go to the Apple Store, have them take a look at it.
Good luck!

[SOLVED]Cannot detect battery or power supply before a power event

The system cannot detect my battery (or AC adapter) since boot, and before a power event
like the following: (the acpi command provides no output)
$ acpi
After I do one of the below
1. plug in AC adapter
2. remove AC adapter
3. cover my screen and uncover my screen
4. drain my battery to low power (probably 15% or 20%)
The system can detect my battery/AC
like the following:
$ acpi
Battery 0: Charging, 61%, 01:18:24 until charged
$ acpi
Battery 0: Discharging, 61%, 05:17:15 remaining
Is this a bug or solved issue?
or should I update my bios?
NOTE: This issue does not exist in Windows (8.1), on the same machine
The laptop is Dell Inspiron 14 7437, without touchscreen

I'm glad I could help!
To complete the answer on whether it's a bug or not, it has to do with your BIOS expecting Windows rather than Linux. So you need to tell it that Linux is running and without the parameter, the kernel will return false if asked whether Linux is running. This causes some features to just simply not work.
If adding that parameter makes the screen's backlight to not work, you may want to add "acpi_backlight=vendor" to it also, but it actually caused my computer to not boot and seemed to not make a difference (probably should have mentioned that).

My ipod will only charge on the docking station. says it has a full charge but when I take it off the docking station it says battery is low so I've plugged it into the usb and plugged it into my wall outlet but it is still not charging. Help?

my ipod will only charge on the docking station. says it has a full charge but when I take it off the docking station it says battery is low so I've plugged it into the usb and plugged it into my wall outlet but it is still not charging. I'm not sure what generation it is, its an 80GB. Help?

The battery is possibly unable to take as much power as a normal battery. It may need a replacement battery.

Hp mini display only comes on with power cord plugged in

I have a mini 210-3000 that fell on the floor a while back. After that the display will only come on (the system is completely booted up) with the power supply plugged into the jack. The cord doesn't need to be plugged into the wall, just plugged into the notebook. Everything else works perfectly.
Took to local repair guy and he couldn't figure it out.

Hi @mikeybr550 ,
Thank you for visiting the HP Support Forums and Welcome. I have read about your HP Mini 210 and battery issues.
You could check this document on testing and calibrating the battery using HP Support Assistant. It gives HP Battery Check results with links that could help.
Have you removed the battery and inspected the connections?
Please let me know how this goes.
Thanks.

MBP random shutdown even with power cord plugged in

My MacBook Pro (original) has now randomly shut down 5 times since I installed 10.5.6 the week before Christmas. 4 of those 5 times happened with the power cord plugged in, the green indicator light on and the installed battery fully charged. I have two batteries and it has happened with each of them at least twice. Yesterday I got my first shutdown while on battery only. After each shutdown I was able to restart the computer and it operated normally, even the one on battery only.
These shutdowns are fast and complete. There is no warning of any kind. The screen just goes blank. It is not sleeping, there is no pulsing light on the front. Using the start key begins the process from scratch with the Apple "startup chime."
The occurrences have gotten more frequent. The first two were within 24 hours of when I installed 10.5.6 and they happened within several hours of each other. Both of these were with the power cord attached and fully charged batteries. I swapped the battery after the first one. When it happened again, I swapped them again.
The next time I had the problem was 1/30 (last Friday). The only significant software installation I had done between installing 10.5.6 and then was to install iLife '09 on 1/28. All software updates had been installed in a timely manner. Friday the laptop was plugged into external power and the battery was fully charged, but I don't know which battery was installed.
2/1 I had an issue where my computer couldn't locate the OS file on startup so I did a archive and install. It operated normally since then until yesterday, 2/4 when I had two shutdowns. The first I had the computer on external power and a fully charged battery. The second was the ONLY time I have had the shutdown occur while on battery power only. I was on a flight when the second shutdown occurred. I had used all the power in the battery that was installed when the first shutdown happened (down to about 11 minutes remaining). I then swapped batteries without shutting the computer down. The system rebuilt itself normally and I began working on iPhoto. About an hour later it just shutdown. I was able to restart the computer normally and used it for another 45 minutes or so before I shut it down for landing.
I called Apple Care this morning and they advised me to get an appointment with a Genius. I resist being without my laptop but will try this and let them look over the console log to see if they can find anything.
I have done all the basics, reset the PMU, zapped the PRAM and repaired disk permissions. The next thing I am going to do is to calibrate both batteries. I doubt this will have any impact on the issue because most of the shutdowns have occurred with external power connected. I just haven't done this in a while.
Any ideas out there? Anyone have a similar problem?
I have another issue on my Mac Pro since installing 10.5.6 and my wife's iMac G5 has a completely different issue since installing 10.5 (I didn't install this OS until last week so I could get the new iLife on it). Seems like this latest OS version is a bit buggy or at least incompatible with a lot of Apple's products in different ways.
Fight On!

UPDATE:
Service was due and now that I saw the machine fail 4 times in a day doing the same process I knew I could duplicate the issue on demand. That's a big bonus.
Called Apple Care yesterday morning and the guy I spoke with read over the notes on my case after I told him what happened the day before (black friday, 4 shutdowns). While he didn't transfer me to a Product Specialist, he did talk to one for quite a while (I was on hold for about 20 minutes while he did this). He said I could ship it to Apple and they would look at it or I could take it to an Apple Store or Authorized Service Center. Thinking this was the next step I had secured a time at the Carlsbad Apple Store for late that afternoon (my usual & closest store, Escondido, was booked all weekend). They told me to take it in and reference the case number. The Product Specialist thought it sounded like a logic board and would duly note that diagnosis in the case history.
After the conversation ended I decided to make sure I could cause the failure. So I started the process (threw out the face.db from the iPhoto Library package and opened iPhoto whereupon iPhoto begins a scan of the images for faces. Having over 12,000 images gives it a lot of work). This time I decided to monitor the workings of the laptop using iStat Pro (freeware widget download & I recommend making a small donation it's so good). I kept track of the processes at 5 minute intervals, the CPU usage, numerous temps AND the fan speed. The latter seemed to be the critical. Shortly after the fan speed got to 4700 the shutdown occurred. It took 36 minutes from the time I started. The fans kind of confirm to me that it could be the logic board.
I took the laptop to the Apple Store and started the process in front of the "Genius." He read through the case as well as the printed copy of this thread and other notes I brought from previous shutdowns including the data I mined from iStat Pro. He was unimpressed and thought it was a non-issue. I guess that's only fair because I was unimpressed with him. He figures it's my system because of a software conflict somewhere. His answer was to do a clean install and reinstall all the software from the original disks. I told him I have spent over 50 hours on this issue to date and that what he was suggesting would take at least that much and guarantee nothing if it's a database issue...duh! Disagreement. Oh, and he also doubted it would fail just from making it work.
43 minutes after starting the process, well after my "Genius" went home for the day (I was his last appointment), the failure occurred. The "Genius" he handed me off to was working with someone else next to where I was sitting. When the fans hit 4700 rpm I told her it was going to happen soon and as I finished my sentence the failure occurred! Cool.
They have the machine and I'll let you know what they do.
Fight On!

Overheating GPU while power cord plugged in.

Simply put, my laptop's GPU temp skyrockets to 60+ degrees when playing anything in full screen with the AC power cord plugged in to charge the battery... even games like Diablo 2 with low graphic quality.
When I run the games without the cord and simply off the battery life, the temp stays below 45 degrees, but the games run kinda choppy (like Fallout 3 and Dead Space).
Any known reason why it does this, or possible fix... or does it sound like something might be wrong with my video card fan?
Laptop is a Qosmio X505-875

GPU temps of 60+C (range 60-80) are not excessive for gaming. Go to you GPU model website and check the temp parameters.

2009 Macbook Pro's fan spin faster with power adapter plugged in?

I was playing restaurant city on facebook with macbook pro with the power adapter plugged in
( a flash game)
after a while, the fan starts to spin faster and faster and made noise, and the body of the laptop starts getting hot too.
However, when I play the game without the power adapter, the laptop stays more quiet, and the i can't hear the fan spin anymore...(which sounds good)
but what i am worrying is that, is the hardware SUPPOSED to get hot and the fan is supposed to spin faster? the reason why it is not is because the computer recognize the power adapter is not plugged in, so it forced the fan to stay at a lower rpm to conserve power? (which do harm to my hardware?)

Hi
that sounds normal to me - charging the battery produces heat, which must be removed via the fans.
They didn't run slower to conserve power, but because they weren't needed to remove the heat by=product of charging.
Flash is a real cpu burden.
