Dv6 shutsdown randomly on battery power

Hi,
my son's dv6 (win7) doesn't like to run on battery power. Battery is 100% charged, pull out the power, it randomly shuts down. Sometimes runs for 10secs, sometimes 1min or more, but then it just dies.
I just bought a brand new battery, it didn't fix the problem.
Also when I close the lid on battery power, it never wakes up, I have to hold down the power button for long time, then it starts in.... "this computer did not shut down properly" mode.
The HP Diagnostic software says battery is OK.
Any ideas?
Exams start in a few weeks and we need him studying - not troubleshooting computers!
thanks in advance.

Try to update the latest BIOS from the Support and driver download page for your notebook model.
Once this is done, you can run startup diagnositcs on your unit from the BIOS to check if there is any hardware issue on the notebook.
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c01443317
This should help you identify if there is any hardware issue on your notebook.
Also the battery that you have replaced, is this a geniune HP battery? The Battery check on the HP Support Assistant software should be able to tell you if there are any battery issues if anything exists.
Hope this helps.

HP Envy 14 (2020NR) - randomly missed keystrokes after wake from sleep (on battery power only)

While running on battery power, sometimes when I wake from sleep, keystrokes will randomly be missed. It doesn't always happen, and I need to do more experimentation to figure out just how often it occurs. To fix it, I just reboot the computer (while still on battery power), and the problem seems to be gone. It can also be fixed by simply plugging in to A/C power. I am using Windows 7 Home Premium 64-bit.
I have seen similar threads where people say that repeated keystrokes are missed, or rapid keystrokes are missed -- but so far those threads have remained unanswered, and my problem seems a little different in that no one else has mentioned a correlation with running on battery power. The problem never occurs otherwise, for me.

If you are still under warranty you need to return the laptop for service. If not I am afraid it is a motherboard issue requiring replacement. You have done all the diagnostics a professional would do. The fact that the battery works in another computer tells us it is not the battery.

Powerbook G4 randomly shuts down even with full battery power

I have a three and a bit year old powerbook g4 (my apple care ran out in November) that has recently - as in the last two days - started randomly powering down without warning or error messages, regardless of how much battery power I may or may not have.
A bit of history - not sure what is and isn't pertinent.
I only recently - about six months to a year ago - switched out my recalled battery for a replacement one.
I also received a new power cord under warranty within the last year - but have had no problems before.
Before my powerbook came out of warranty, I took it into my local genius bar to have tests run to see if anything was wrong that I was not aware of, hoping to be able to get it fixed while still in warranty - it came back to me with no repairs and a clean bill of health.
I was on vacation for two weeks, and while on vacation my powerbook sat - powered down - in it's bag untouched the whole time. The problems started (or at least I first noticed them) within a few days after returning.
The other day, before any of this started, I noticed that even though the power adapter was in and glowing, the battery charging icon said "not charging".
The second time the random power-off happened, I did notice that the battery icon had an "x" in it, before it shut down.
The shutdowns are not like proper shutdown processes... one minute the computer is on, the next it's not. It's like the computer thinks there's no power, regardless of the actual charge of the battery.
I use my laptop on a laptop tray to maintain airflow underneath it and reduce overheating, but even so, the laptop seems to get very hot (although this is one of the issues I was worried about when I took it in to the genius bar before the warranty ran out, and they said it didn't get any more hot than they were supposed to), and also the power connector gets very hot. I don't know if overheating might have something to do with it?
So far I haven't noticed if it has happened while I've had the AC adapter plugged in... I think it only happens if it's running on battery, but not completely sure of this.
After the computer shuts down, I can restart it immediately (though these days it is taking longer) and I do not receive any error messages.
I usually turn off my computer when I won't be using it for a while - like before I go to bed or to work.
I recently upgraded my OS from panther to leopard, but was assured that it was compatible. I've had Leopard installed for at least three months, and the problems have only just started, so it probably doesn't have anything to do with that.
Well, that's about every possible piece of information I can think of that might be at all relevant to the situation. Does anyone have any ideas about what's happening? I have a feeling the news is going to be bad and I'll probably have to get a new computer...

Here's the Apple article on how to reset the PMU:
http://docs.info.apple.com/article.html?artnum=14449
Possibly this might fix the problem. If not, here's a link to the MBP battery program:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
This program does NOT apply to your battery, but I think you may recognize some of the symptoms that yours is exhibiting. It also sounds like your power adapter may be getting warmer than it should, but that could have to do with the battery being defective. But if less than a year old, the power adapter should also be under its own warranty period.
If you have access to an Apple Store, you could make an appointment with the genius bar. They should be able to evaluate both the battery and the power adaptor by swapping yours out with ones that are known to be good. If not, call Apple.
Good luck!

HP DV6-6B25TX shutting off after 10 to 15 seconds irrespective of battery power or AC power

Hi,
MY DV6-6B25TX is shutting off after 10 to 15 seconds irrespective of battery power or AC power.
Following is the complete scenario of what happened during the last few weeks:-
Two weeks back i was using the laptop with the AC adaptor plugged in for charging, the battery got charged upto 99% then it stopped charging and the battery icon text displayed, 'Plugged in, Not Charging'.
A week back the battery was 20 %, after plugging in the charger, still the same message 'Plugged in, Not Charging'.
Now the laptop doesnt respond to the power key when the battery is inserted.
If i remove the battery and again put it back, it starts without pushing the power button and shuts off after 10 seconds, i.e. even before starting Windows.
It shuts down even when on Bios Screen, so OS is definately not the issue.
When i connect the charger and press the power button, same thing i.e. starts and shutts off after 10 to 15 seconds irrespective of BIOS screen or Windows Boot.
I removed the ram and but it back again but still the problem persists.
Also there is no question of overheating due to dust as i have barely used the laptop for a few hours, the laptop is around 6 months old and under warranty.
Please Advice ASAP.
Thanks in Advance.
This question was solved.

Honestly, something is preventing the battery from being charged. The notebook shutting down seconds after reinserting the battery is a good indication the battery just isn't getting charged. This could be a failed battery, charger, charging port, or motherboard in rare instances.
Since it is in warranty, I recommend contacting HP support as there is no easy fix for this on the forums. It is a hardware issue.
The number for support in the U.S.A. and Canada is 1-800-474-6836.

HP Pavilion dv6-2190us Notebook PC Battery Won't Charge & Will Now Only Run on AC Power

OS: Win7 (64-bit)
Serial #: [Personal Information Removed]
First off, I will say that the main battery I am using is not an HP OEM battery, however, it has been verfied to work and charge correctly in another family member's dv6 notebook. Furthermore, I have access to an HP OEM battery, from a family member's dv6, with which I have confirmed the same issue. FYI: I replaced my OEM battery about a year ago with an aftermarket battery when my OEM battery stopped holding a charge. This happened after before my laptop was 2 years old.
So, here's a description of the problem. About a month ago, even though my laptop was plugged in to the AC adapter, the battery stopped charging. The laptop continued to work until the battery completely ran out of charge. Once that happened, the laptop shut down, DESPITE still being connected to the AC adapter. At this point, as long as the battery was installed in my laptop, with the AC adapter still connected, it would not power up. The only way I could get it to power up was to remove the battery. Then, it would boot up just fine, but of course, I was now tethered via the AC cord, turning my laptop into a "thin and light desktop". If I attempted to put the battery back while the computer was on, connected to the AC adapter, it would shut down IMMEDIATELY. I took the battery and plugged it into my family member's dv6, at which point it charged just fine and worked normally. I then took the charged battery and put it back into my laptop only to have the same sequence of events repeat, i.e. laptop ran off of the battery despite the AC adapter being plugged in until it ran out of charge...had to remove battery to get laptop to start back up. I have also confirmed the exact same behavior with the HP OEM battery out of my family member's dv6. So, in a nutshell, it would appear as though my laptop has lost the ability to charge batteries and cannot resolve the fact that the AC adapter is plugged in when a dead battery is installed.
It should be noted that despite the normal operation of my family member's dv6 with my battery and the normal operation of my laptop with just the AC adapter plugged in, I did verify (via a multimeter) that the voltage of the batteries were within normal operating range and that the voltage and current flow of the AC adapter was within normal operating range.
Is there a separate charging circuit inside the dv6 for charging the battery? Is it separate from the motherboard and possible to replace? I've done quite a bit of research on this issue (or very similar issues) and despite some suggestions RE: BIOS issues, I just can't see how that could be the culprit. Nor can I see how "re-calibrating" my battery would address this problem. Note: battery does register at 100% when charged in the other dv6 and put back into my dv6.
Ok, I hope that clearly explains the issue. Please let me know if I can provide any further details to help troubleshoot it.
Thanks,
Eric

Okay, so the type of battery you have is designed to last approximately 1 year (see link below) it has lots of links to other useful docs too.
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00596784&cc=us&dlc=en&lc=en&product=4121239&tmp...
HP & other companies do sell Long life batteries but they cost more.
We would ask you to put the unit in our unit and run Battery check which is inside HP Support Assistant, make sure you have the latest version, same for your BIOS Version.
You will see there are bunch of tips on how to make your battery last longer, but you really need to start doing them from the start, if your battery is already 1 year old there is a good chance it is low enough on it's capacity to require you buying a new one.
You should check out our site, they often have sales, and Batteries would be under accessories.
Check out other sites too, compare.
Good luck.

T61p freezes randomly when on Battery Power

I recently got my new T61p and i'm absolutely loving it. However, randomly (and only when the laptop is not plugged in to AC power) the system will hang on certain tasks, usually web surfing since thats what I'm usually doing, and I'll have to do a hard reboot. Consequently, internet explorer and mozilla firefox tend to freeze sometimes when I'm on battery power. When I'm plugged into AC power everything runs perfectly.
According to this website http://www.utheguru.com/lenovo-ibm-t41-random-crash, this guy had similar problems with his t41. I have all the latest versions of power management and updated all drivers and patched vista. Any ideas on what to do? I don't want to uninstall power management b/c its so useful
edit: I use the 'Energy Star' profile for my power setting
another edit: Apparently it is to do with the Intel turbo memory. i'll try the solutions in this post and give u my progress: http://forum.thinkpads.com/viewtopic.php?t=51908

I got my T61p last Friday. I'm having the same issues after applying all patches and driver updates. I can run fine on AC power, but as soon as I unplug the machine, the screen goes blank and I have to do a hard reboot. I have not been using Turbo Memory. For a few days it worked just fine, but then the problem started up again yesterday. I think it has something to do with the GPU.

Macbook randomly shuts off while on battery power.

I have a 13-inch Macbook, Late 2008 model, using iOS Mavericks. While on battery power, the laptop will randomly just turn completely off, despite still having plenty of battery power left. I know it's not a calibration issue where the battery is dead but appears to have charge left, since I'm able to turn the computer back on again and continue using it.

First try the SMC reset appropriate for your model: Intel-based Macs: Resetting the System Management Controller (SMC)
The information you posted says "Condition: Service Battery" - that likely means you will need a new battery sooner, rather than later, especially if an SMC reset doesn't help the situation at all.
In any case, when new, your battery likely had about 4400 mAh (milliAmphours) Full Charge Capacity.
The Full Charge capacity is down to about 60% of original capacity 2600/4400
A direct replacement from Apple is $129, installed.
Any popular search engine will provide a list of less expensive suppliers, but I cannot recommend any, simply because I haven't used any non-Apple replacement batteries recently. My single experience with one lower-cost supplier for my polycarbonate 2007 MacBook (replaced in 2010) was that the cheaper battery needed to be replaced again within a year. Your mileage may vary.

Laptop randomly switches off when on battery power.

When on battery power my HP DV3500EA laptop randomly switches off (this is only a recent problem). This is when there is still significant charge on the battery. This does not happen when on AC power. Once it has switched off, the laptop is able to be switched back on again and run normally until the next time it switches itself off. It doesn't shut down, it just turns off immediately as if the battery has run out. I have checked that it is not overheating - the CPU temp is generally between 40 and 50 degrees Celsius. I know this isn't a software problem because it does this on different operating systems (Windows Vista and Ubuntu Linux). I assume this means it must be a hardware problem, but I can't work out what it is or how to fix it.
Does anyone have any ideas?

Exact same problem with my Envy 13 running with windows 7... any solution besides bringing the laptop back to the store?

Randomly Shutting Off When On Battery Power

So, I recently had my logic board replaced because my built-in audio out port wasn't working. I had this done more than a week ago, but just 2 days ago I was using it without being plugged in for over an hour (the battery indicator said I had about 50 minutes left of power) and then suddenly, it just shuts down. I hit the power key, and hear the startup "ding", and then hear it shut down seconds later. I plug it in, and start it up, and it works fine. Then last night I was using it on battery power again, and when the battery said 57 minutes left, it just shut down.
Could this be from my new logic board?

Hi E,
Unlikely, but possible. More likely the batt is dying. Time indicators have never been known for their accuracy, and a batt starting to die increases that problem. Check the condition of the batt (Apple Menu:About This Mac:More Info:Power) and post back.

Peep sounds when working from battery power

Hello
I bought a new HP DV6-1340 laptop
I hear some strange peep sound from the notebook hardware when its working from battery power.
When working from outlet power there is no peep sound from the hardware.
Maybe its because the battery is new or something there wrong ?
Thanks in advance for help

I solved it my self. It was OK (no buzz and fuzz) when it was plugged in (when the electicity line was down once and I was running on the UPS battery).....

IPhone 5 shuts down at 37% battery power...

This has happened 6 times now - all random times (twice when using FaceTime, twice when taking pictures and twice when texting/emailing). When I try to reboot phone I get screen that shows no battery power remains and that you need to plug in phone. I then plug it in and it powers back on and jumps to 47% battery power. Anyone have this experience??

I, too am seeing this happen lately. I'd guess it's because my phone is a year old now but I'd prefer it to be something else. :)
I should mention that I'm still running OS6. I did the "upgrade" to OS7 on my iPad and I HATE it! I figure that eventually I'll have to move up to the new OS sooner or later but I'm holding off as long as possible!
Has anyone had any success in tracking down what the problem actually is?

Battery Power Half of What it Used to be

Hi there,
I bought my macbook for class and everything has been great until a few weeks ago.
I used to be able to set my macbook on the lowest setting for brightness and I could make it through 2 an hour and a half classes, and then around 20 minutes of my next class (mind you I usually plugged it in by the time my third class rolled around). Now I can make it through one class, and it ends up dying in my second class. My school isn't very technologically friendly so I am rarely ever able to get a plug so I don't have to run on battery.
Model Information:
Serial Number: SMP-bq20z951-3957-6ad

Health Information:

There's my battery information.
I don't understand why the cycle count is so high considering I only go to school 2 days a week and I never turn on my macbook otherwise.
I don't really have any programs running (any that take over 30% of the resources, they're all around 5). I have bluetooth disabled, and I also did that thing (sorry I can't think of the name) where I drained my battery, put it to sleep, and then charged it 5 hours later.
Now here's what is weird. The other day I was just testing my battery power and I had the brightness on full, and I was watching videos on youtube and had the sound on and the battery lasted around the same time (2 hours).
I don't really know what has changed, but I'd like to know what I'm doing wrong so I can fix it.
Thanks!

Keep monitoring your battery. Download [iStat Pro|http://www.islayer.com/apps/istatpro> to view your health whenever you go to the dashboard. If you find that the health is ever decreased make sure you take a screenshot of Apple System Profiler showing the same decrease in mAh or "Check Battery".
I had the same issue where the health would jump around randomly but when I was actually at the Apple Store the first time everything was fine. The second time, I had more screenshots and it was bad when I was there so they changed the battery.

Computer turns off without warning on battery power

Starting a few weeks ago I've found that my Macbook Pro has been turning off without warning while on battery power. The first time this happened it was after about an hour of use and now it happens within a half hour or less. If I try turning it back on it shuts off before OS X is fully loaded. According to CoconutBattery my battery's health is at 97%, so the battery isn't losing overall charge capability. When I'm on battery power it says I have 2-3 hours of battery life left. Sometimes I notice this will drop between 1-2 hours after 20-30 min of use (if it'll stay on that long) but it never drops and gives me a warning of low battery. It just shuts off without warning. If I press the button on the battery after this happens I do get 4 out of 5 lights. This never used to be a problem. My computer is 14 months old. I've replaced the battery once about 8 months ago (under warranty) because my original battery was losing capacity very quickly. Because 14 months have passed I can't simply get a new battery under warranty. According to Cocoanut Battery and the Finder my battery should last near it's full capacity. I can't figure out why it's randomly shutting off. I have had all the latest updates including the recent battery patch. Any help would be greatly appreciated. I will award "solved" for a solution and "helpful" for posts that contribute to the solution. thanks!

Actually (and fortunately), that's incorrect. Apple extended the warranty for all Core Duo notebook batteries to *2 years* from date of purchase. Details are here:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
Your full charge capacity is fine (as you noted). But one of the symptoms listed on the linked page is +"Battery exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300."+ The word runtime in there applies, so I would call Apple or make a Genius Bar appointment and head into a store. (I did the latter, they replaced mine - free of charge - 15 months after purchase, no AppleCare, and no hassles).
Hope this helps...

Unreliable WiFi connections when on battery power

I've had my MBP for 2 weeks. It worked flawlesly for the first 10 days. Since then, when running on battery power, my WiFi connection drops repeatedly, and at random intervals. Signal strength is good always (on a/c pwr or batt) and I am always able to reconnect via the menu bar by re-selecting my network.
I believe that this started happening after the latest updates were downloaded and installed.
Again, this only happens when running on battery power...
Any ideas?

This is an issue that has appeared in many threads. It looks like OS X Tiger has a driver issue with certain wireless APs - something related to power management.
In my case, I had no trouble with my Netgear AP but when I recently switched to a Linksys running DD-WRT open source software, I would drop my connection on battery every 2 minutes or so.
Same computer using Windows has no drops. I have not seen any press that Apple has admitted to the issue.
Until then, use the workaround that has been suggested. Run the Cococonut Wifi. This is a menu-bar utility that shows a count of open APs in the area. However, the side-effect is to keep the wireless driver open and stop the disconnects. It worked for me. The URL is: http://coconut-flavour.com/coconutwifi/index.html

Shutdown Immediately on Battery Power

Hi everyone, I did a search but didn't find anything exactly the same as my problem so I was wondering if anyone had any suggestions.
I have a regular Macbook, 3 years 7 months old. As soon as I unplug the power cable it shuts off, every time without fail so it isn't a random shutdown.
When trying to boot up whilst on battery it dies straight away.
The battery has had 514 cycles and still has 89% capacity and is fully charged. Also, when pressing the button on the battery itself, all the lights go green, so I am assuming it isn't a problem with the battery itself.
When plugged in to the power it works fine, but the MagSafe adapter keeps falling out when it gets knocked or someone steps on the power cable and the laptop just turns off lol!
Thanks in advance,
Oliver

Well, if the battery says its charged in OSX & via the lights then I'd say it may be the connectors on the MacBook itself that, at some point, started failing.
... Well maybe not the connectors directly but possibly something that transfers the battery power to the main logic board.
