Power Manager & Battery Charging Problem

With upgrading Power Manager 3.05 to 3.11a, my battery may not charge even if it is plugged in. I have custom thresholds: 77% & 93%. However, it is not charging now, even through the battery is at 45% (which is below the threshold of 77%). The Power icon in the Notification Area of the taskbar shows that is "45% available (plugged in, not charging)"
When this problem happens, I can get it to work properly for a while again by unplugging the AC adapter and plugging it back in. I have BIOS version 7UET82WW (3.12 ), but I believe the problem existed with the previous BIOS version and Power Manager 3.11.

I have it set now to always fully charge to 100%, but it is not charging at 95% available. I have even uninstalled and reinstalled the Hotkey package, System Interface driver, Power Management driver, and Power Manager.
Oops. It might be normal behavior. I'll report again later.

My solution (or so I thought) to Power Manager/CPU throttling problems!!!

I have found a solution to all my Power Manager/CPU throttling problems!!! Though there is some good and bad news.
{EDIT: The problem has NOT been fixed, even after latest PowerManager (3.62) and BIOS (1.30) versions. Pretty much ignore anything I say below as the problem is still occurring. You can see my full post here: http://forum.lenovo.com/t5/W-Series-ThinkPad-Laptops/W520-Speedstep-not-working-properly-on-battery-...}
Good news: I have NONE of the throttling issues or inconsistent CPU frequency problems I was having before on AC or battery power. Everything, including TurboBoost on battery works! It is completely fixed! (I have no idea how this factors into Lenovo’s statements that TurboBoost is disabled on battery “by design”. There is at least one other post from someone else that also reported TurboBoost was working for them on battery)
Bad news: I don’t really know which one of the many things I tried actually worked. I am sorry I wasn’t more methodical about recording what I did and checking results, but this was my last ditch effort to get this fixed on my own without sending the system in for repair and frankly, I didn’t think it would work. Now that it has worked, I’m hoping my steps can help others.
For anyone interested, here’s what I did… and before anyone says something like “That has nothing to do with managing power/cpu, why would that help?!… etc., please keep in mind I’m just stating exactly what I did. I am aware some of the steps may not be relevant, but who knows… We all know how weird PC’s are sometimes, even the smallest, oddest thing may resolve a problem.So anyway, here goes.
**IMPORTANT** Not sure how many noticed, but there was a new version of Power Manager released a few weeks ago, 3.62. The PM driver seems to have stayed the same. That alone could very well be the sole fix, I’m not sure. You may just want to completely remove PM and PM driver and install the latest version before trying any of the steps below.
1)Made a complete system image via Windows built-in backup feature
2)Disable any 3rd party fan/CPU control utilities (Throttlestop, etc). Make sure they are also not going to run at startup or from a scheduled task
3)Remove Power Manager Driver, then remove Power Manager software
4)Reboot to Windows
5)Remove all traces of the Power Manager drivers/software directories (think it was something like C:\readyapps and C:\drivers.) **For some odd reason after I did this, my wireless stopped working but it resolved itself by the time I was done with these steps, strange
6)Reboot
7)Access BIOS and reset all settings to default
8)Boot into Windows, downgrade to BIOS 1.25 [UEFI: 1.25 - 8BET44WW / ECP: 1.14 8AHT32WW ] via the Windows flash utility. I wanted to downgrade all the way back to 1.06, but the software would throw up some error for any version prior to 1.25 and wouldn’t proceed
9)Reboot to Windows; make sure system booted w/ out issues
10)Reboot again, access BIOS, reset to defaults again
11)Shut down system
12)Disconnect AC power. Remove main battery. Access and disconnect system backup (a.k.a CMOS) battery under keyboard. Discharge residual power in the system (there are various ways to do this, but you could just leave the battery disconnected for a few minutes). Visually inspect the system for anything funky…my system had a slightly but noticeably loose CPU/GPU heat sink/fan assembly power connector.
13)Reconnect backup battery.
14)Reconnect AC power but leave main battery disconnected.
15)Power on. Should get a message indicating “checksum error, system time reset” or something like that.
16)Reboot to Windows. Verified still okay.
17)Downloaded latest BIOS version, 1.26. This time I burned the bootable BIOS flash CD instead of running it through Windows.
18)Restart and boot from disc, flash BIOS to 1.26. Once complete, restart. Verify BIOS set to defaults.
19)Boot back into Windows.
20)Install latest Power Manager driver (1.62 ), reboot if/as prompted. Install Power Manager (3.62), reboot as prompted.
21)Boot into Windows, verified Power Manager was active and working. Verified TurboBoost was working. Restarted system a few times and played around with Power Manager for a bit to see if the different power plans worked and retained the settings, all the while monitoring the Intel TurboBoost utility and PM’s own “power gauges”. Let system Sleep, changed power sources, resumed, etc. Everything was working great.
22)Shutdown, reconnect main battery. Booted into Windows. Again, fiddled with Power Manager for a bit, switching between power plans and AC/battery power. Still worked great.
23)Success!
That’s it. Again, this is not a guaranteed fix guide. These are just simply the steps that I took on my system that resolved the problems many of us are having. Hopefully it will work for others.

Now, I did chipset first (didnt ask to reboot) then installed the PM driver (did ask to reboot)
I rebooted.... then I went into bios (1.26) and set everything to default... then restarted saving changes...
Since I prefer not using optimus I changed the display settings in bios right after saving the default settings...
Not sure whether or not you really had to go into bios... but everything seems to be working...
My settings in PM is set to Maximum Power in the Advanced tab, 3rd party monitoring tools is TPFanControl and HWInfo64....

Satellite A60: battery charging problem

Hey,
I have a toshiba satellite A60 notebook. My notebook is 2 years old. After I used my laptop in battery mode, it fell out because the battery was empty. When I plugged it in on the net, the battery led flashed amber for less than a second and went out again. The battery won't charge anymore and the batteryled is out.
Windows detects the battery though. The laptop still keeps running on the battery for some minutes. I already had this problem a year ago and after a few months the battery started charging again.
Does anyone have a simular problem and how do you solve it?
Thanks (sorry for the bad english)

Hi
Possibly the battery cannot charge properly because it has a malfunction.
Generally the battery performance decreases in process of time.
I read that you can charge and discharge the battery about 500 times and then the performance goes down.
You can try to remove the battery for a several time. After this time try to charge it.
I would also recommend checking if this issue happens also with a new battery.
But its also possible that there is something wrong with the power supply electronic.
This could have a bad influence on the charging procedure.
I have also read that the BIOS update have solved some battery charging problems.
But if the battery charging has worked since 2 years so I assume the BIOS is ok.
However, check it with a new battery.

2nd dead iPod Touch 4G in 2 months? Battery/charging problems!

Hi everyone,
It seems as of tonight that I will have to return my second iPod Touch 4G in the last two months. In both cases, it was an issue where the device would no longer charge, and became very hot on the top of the back panel when the device was turned on even for a few seconds (while not being plugged in). In the first case, the device seemed to be defective from the time I opened the box, which was confirmed at an Apple Store, but they asked me to ship it to Apple Repair to be checked out. Apple took a very long time to get a replacement to me, but was good about that problem, and I was happy with the replacement for the past month when all of a sudden tonight the new one would not change and became very hot.
Is this an issue that anyone else has seen? I essentially only charged it off of my laptop or a wall charger unit, but it seems like the battery essentially is shorting out. I love this device, but actually need to use a PDA-type device enough that I am questioning whether I should get a replacement or go back to my old Palm TX.
Thanks for any thoughts/feedback on my iPod Touch 4G battery/charging problems.
Message was edited by: eliotjasper

Most battery complaints complain about loss of charge. The iPod is designed to lose heat through the back as the battery discharges. This is most common when using the device a lot - like playing games. If yours will no loner charge, by all means return it to Apple.
As far as being a PDA goes, it is as good as any smart phone out there. The PDA, as you once knew it, is dead and has been for 5+ years. Take your iPod to an Apple store and insist on a replacement.

Power Manager only charges 8-cell battery upto 36%

This problem is about to drive me insane.
It's new thinkpad X200 tablet and new 8-cell battery, only having 4 charge-cycle count.
I've just discoveried this problem when I upgraded to Windows 7 Pro and updated Power manager to V3.05 of my X200 tablet, but since it's on AC power most of time and I've set battery charging only starts when level below 5% and stop at 100%, therefore my battery only being recharged once or twice a week, but whenever it charges from 5%, it will just stop at 36% and display "charging will start when below 5%", so I will have to change the option in "battery maintaince" in Power manager to "alway fully charge" to have the battery 100% charged. But, I don't really want to choose the alway-fully-charge option torepeatly recharge the battery at near 100% since I have only a few occasion during the day where I need to rely solely on the battery, which only consume it down to ~90%.
I'm not sure whether the problem is due to the new version of power manager which regard my 8-cell battery as 4-cell?( logically, then it should stop at 50%, right?).
The battery once did charge on the ultrabase, but I can't remember if that was the time when the problem started.

Power manager battery maintenance problem

Hey,
When I tick the custom charge threshold and enter any values in power managers battery maintenance. The only thing that happens is the battery life % doesnt change when disconnected from AC and with AC connected it just charges it to full and stays there.
I'd like it to keep the ac in and get it to charge when battery life is 5% and stop when 100%.
Any ideas why it doesnt work?
ThinkPad R500 2732-6EG running Win XP

Hi,
althought I'm not sure, if the last update means, that you will dissable the Threshold, however, this feature is one of the options, how some customers keep the battery up to date.
Here is a situation, so that you understand:
- the notebook is all the time on AC and the only time, then the Notebook is unplugged is then they are moving with him and once the notebook is started, it is pluged back in to AC.
So this situation is not letting the battery to be offloaded and the battery is still between 96-100% of changed state.
This above situation is not the ideal one, and therefore the Threshold was added to the Power manager, so that the battery can be discharged and charged back if some percentage of the battery state is reached. Additionally we have added the option, so that you can select by yourself, what should be the threshold so that it will not be only hardcoded. This is more user friendly
So resume:
- if you are a user, like I described above, then it's not a must to use Threshold, however, it's a good idea, as when you read abot the batteries in Notebooks, then you will find the inforamation, that it's by every producer recommended, that the battery will be sometimes almost below 10% of his state and then it will be charged, so that the maintanance of the battery is on a better level.
Maybe this explains you a bit the situation and the scenario, that you want to have and also bascialy this might tell you if you want, or don't want to use the Threshold.
Feel free to ask any add quesitons to this topic.
Cheers

Y50 battery charging problems

hello,
received my new y50 a few days ago and began seting it up. the first few hours it was working fine. battery charged up to the full 100%, i then disconected the power cord to let the battery drain down to about 20%. i then plugged it back in and shut the computer down left it charging overnight. this is when the problems started.
waking up the next day i turn it back on to see that the battery is only at 21%. no mater how long i left it charging it did not change from 21%. So i decide to unplug it again to let it fully discharge. while unplugged it ran for another ~hour all the time staying at 21% until i finally shut off out of nowhere.
plugged in the cord and turned it back on, battery shows 0% plugged in, charging. but it never gains any % charge just stuck there. i do some reading online and decide to do the generic power down, unplug power cord and remove battery, hold power button for 30 seconds, then reconnect everything and power up. When it boots up the battery indicator now shows 2% and over the course of the next 10-12 hours it increased by mabe 30% more. the indicator NEVER changes its percent the only way to see the change in the charge is to shutdown/restart.
today is the third day and after many hours of use i got stuck at around 76% (only reaching this number by restarting every few hours to get a new updated battery charge%) since it stayed stuck at 76% for a while i went for the more hardcore fix ive seen online:
power down> unplug power cord>remove battery>plugin power cord and startup on power cord only>uninstalled the microsoft acpi-compliant control method battery driver>shut down>re-installed battery>plugged in cord and restarted. the driver then automatically re-installed itself and brings me to where i am now.
now a few hours since doing that im up to 83% charge, but same problem remains the only way to update the charge % is by restarting/shutdown and occasionally i can remove the power cord and plug it back in while computer is on and it will update.
Any advice or suggestions on what to do, the 2 main problems i see are:
1. battery charge % doesnt update dynamically, requires power down of some form to update it
2. over 24 hours of being 'plugged in,chargin' just to charge ~80%

i have found the culprit to the problem, but it is one that doesnt make much sense to me.
if i try to install the intel video drivers from the y50-70 drivers page in lenovo support, or if i try to install the intel video driver from windows update, i lose the functionality of the battery indicator. it does show when its connected to ac or runnig on battery power, but it wont update the % load nor time remaining. only way to charge to full is when off.
i did ANOTHER fresh install and am currently running with all drivers installed except for any version of intel video driver and the battery indicator and charging times when powered on are functioning.
any chance to get new intel video drivers for win 8.1 for hte y50-70?

MacBook Battery Charge Problem - With a Twist

I got a white MacBook in October to replace an ailing iBook. It ran fine for almost five months, with a slight twist that I've been reticent to come on here and ask about.
Problem #1: The battery charging had what I'd call frustrating behavior. The computer would not charge the battery unless I practically ran the battery down to nothing. Usually it wouldn't start charging until 20-30% charge. My old iBook would start charging at about 85%, so I just figured it was some failsafe that Apple was building in to the new system to improve long-term battery life. This frustration continued until today when...
Problem #2: I went to a coffee shop to do some work. I'd forgotten the night before that I hadn't let my battery run down enough to charge it, so the battery was at 35%. Okfine. I'll run it for a few minutes and then plug it in. I wait. 30%, 25%, 20% and whenever I plug it in to test, it won't charge. I run it all the way down to the point where the system automatically goes to sleep. The battery won't charge. I've reset all the things that can be reset, I've reseated the battery, I've turned it off and back on, I let it sleep for an extra amount of time to squeeze that extra bit out of the battery. No beans. The thing refuses to charge.
In system info, the battery information shows that it's completely dead (remaining power at zero across the board, not the negative numbers I've seen reported in other threads). The power information recognizes that it's a battery with 0% charge, but only says "Calculating until full..." Given that it won't charge, it's going to be calculating for a very long time. The battery flashes one light when I press the button.
I'm going to take it in to an authorized service whatsit on Monday, but in the meantime, what is it likely to be? I've seen answers ranging from bad battery to faulty motherboard. Is there any step I've overlooked to try before resorting to a trip to the store?
Thanks in advance.
MacBook Core Duo White 2.0GHz Mac OS X (10.4.8)

Yeah, if it says your battery is only at 18% of it's charge after just a few months, then there is definitely something wrong with it. They will probably give you a replacement battery, considering it is still under warranty. My iBook (2 Years Old) is down to 29% of it's original charge capacity, so I am in need of a new one myself :\
2 Years is what Apple says is the average life span of a laptop battery.

Power Manager - Battery Maintenance: "Optimize for battery lifespan" question

Having just had a battery failure after only 14 months and 77 cycles (seems some of the cells have failed as it now only lasts about 30 mins despite saying condition good and 3 hours to go - 30 mins later at 4% and takes only 30 mins to fully charge) I just bought a new battery and will be paying much closer attention to managing it using the Power Manager tool Battery Maintenance options.
Have read a lot here and elsewhere about batt issues and thresholds for maximising life. Can live with the conflicting advice too, but what I really want to know is this:
If I select the "Optimize for battery lifespan (automatically change for me)" option and check the box that says "Notify me when thresholds change" - is there any way this little app can be persuaded to tell me what the thresholds actually ARE at any time / at the outset?
It is all very well letting it decide what thresholds for charging/discharging to implement but I would like to know what they are and nowhere can I see how to get this info. And I have not yet had a " they've changed" message and have no idea when I might. I know I'm just the poor sap who pays for the batteries but surely I can be allowed to know what, in its wisdom, the Power Manager has deemed appropriate to implement if I give its own way?
Anyone got any experience/clues as to how to track/monitor the automatic levels when these settings selected?
Thanks.

Hello George,
it seems that the feature to manually adjust the thresholds has dissapeared in newer powermanager versions.
The powermanager is now set to a full automatic and takes care of your battery health.
Simply set it to automatic and relax.
Also I recommend to leave your battery in your TP, it will not harm the battery.

Is the latest version of ipod software causing battery charging problems?

I have access to three different G3 ipods. All of them charged fine (either on AC wall charge or through firewire through the Mac. Now all three have the same charging problem after update to the latest Ipod software. All seem to recharge for only an hour or so then stop charging and show the large full battery icon but when disconnected show less than a full charge on the small meter. If you plug it back into the charger or firewire it will again begin to charge as shown through the large icon. Unpluging and replugging will eventually get to full charge on the small icon it takes at least three times to get it there. It's really annoying and based on the sheer number of posts about this problem,one must suspect that the battery management software must have changed. Has anyone noticed the same coincidence?

Is this problem related ot the 5G ipod?

Power Manager - Battery Stretch options greyed out

When I am running on battery, the various checkboxes for the Battery Stretch options are greyed out. Normally they are only greyed out when running on AC power, but mine are greyed out all of the time. How do I fix this?
I suspect became got corrupted in the registry. I had the problem described at http://www.brandlehner.at/Brandlehner/cab_blog.nsf/d6plinks/CBRR-6YWBNV but managed to fix it.
Windows XP SP3, T61 7551-V51, Power Manager 1.73, Power Management Driver 1.60.0.4.
Any ideas would be greatly appreciated, thanks.

Hi,
in case you want to use this option properly, make sure, that you have the latest version of Power manager, Poewr management utility, System interface driver and Hotkey installed.
In case once of them is older verison, especially Power management driver, then this situation amy appear.
Let me know you system type and the model .

Yoga 3 Pro Battery Charging Problems

I've combined several discussions into one because there are multiple cross-overs of symptoms.
After reviewing all the posts, I see there are two types of problems discussed:
Battery charging but only to a certain percentage
Battery intermittently charging
Several people have reported success with their limited battery percentage problem by following the solutions suggested by MarinM and Vladtech.
For the intermittent charging, several people have reported that sometimes the battery charges, sometimes it doesn't. I'd like to dig into these reports. I have a few questions I'd like to ask.
When does it charge, when does it not?
Are there any patterns to this?
Does swapping electrical outlets make a difference?
Does the USB 2.0 charging port appear loose?
Does the cable show any signs of damage?
Does the AC adapter show any signs of damage?
When a second device is plugged into the extra USB port on the AC Adapter, does this impact Y3P charging?
Are there any battery error messages?
Thank you for your help,

Intermittent battery charger problem

The green LCD on my Blackbook magnetic end of the battery charger sometimes glows dull when I connect it and has to be disconnected and reconnected again before it glows green . Any idea what's up - connnections are clean and no sign of loose or bet connectors. Intermittent problem that's buging me

I've got the exact same problem, but a little more severe, I'm afraid. It used to be nothing more than what you described, but it seems to get worse over time. In fact, I downloaded that firmware update that was supposed to fix the battery problems the moment I became aware of it, and it has only seemed to hurt. I used to be able to just unplug/plug the cable, and it would work. Now I have to sit for five to ten minutes just to get the dull light, and if it becomes bright to signify charging, the slightest motion stops the charging. P.S. I am typing this on a Windows PC against my will, as I cannot get my MacBook to charge at all right now.

Hp 530 battery/charger problem

Hi all
I have an old HP 530 laptop which came with a 32Wh battery. About 6months ago, I decided to buy a new battery since the first one died out.
I bought a genuine 64Wh 440704-001 battery, because i wanted the laptop to last longer when not plugged.
However, i came up with many problems such as:
(1) The 65w charger was not able to keep the battery charged and the laptop on at the same time.
(2) I decided to buy a genuine 90w HP charger, but i encountered the same problem.
(3) I bought a not genuine 120w charger with appropriate connector, but, believe or not, due to the high current that the battery draws when uncharged, the plastic tip of the connector melts, and that of course leads to serious problems. I bought a genuine hp 90w tip and soldered it onto the 120w charger, and same problem occurs.
I have spent a lot of money just because i wanted a longer life battery, and nothing works right now.
What am i suggested to do, and mostly, why problem (2) exists? A 90w charger shouldn't have solved the problem of the high capacity battery?
Thanks
John

when the cord is plugged in, it doesnt connect into place. like it'd have to be plugged into the laptop and then the cord pushed up against something, like the wall holding into place. i dont think its anything within the laptop. and you have to turn/twist the cord for it to actually light up and charge. otherwise it stays orange and doesnt charge.
