Computer shuts down after disconnecting power
Help! My son has purchased the Envy 15 and loves it BUT we have an issue with the battery. He has both batteries connected and the laptop plugged in. He unplugs the laptop - both batteries are at 100% and within a minute, it shuts off. It doesn't shut down, it's like it suddenly doesn't have power. The machine will reboot, on the batteries, no problem - but of course, windows hasn't been shut down, so its not a "graceful" reboot. When looking at the battery power after, Battery #1 is at 100% and Battery #2 is not present. It obviously has power as we can reboot without reconnecting the power. It only appears to happen when the second battery is connected. We are on the HP recommended power plan with no adjustments.
When I plug it back in, it still says there is no second battery present.
Help? Any ideas?
Plus, does anyone know if you can lock the function keys - he does a ton of gaming and uses the function keys, so the direct action keys are not a plus for him.
thanks!
CarolineSounds like battery #2 has a short. When the system detects a critically low battery, it is likely to devote all power to battery charge until the batery reaches 5% or so. Try each battery seperately. If no power at any time, remove the battery, disconnect the AC adapter. Press the power switch for about ten seconds. Then connect the AC adapter, let it boot, then install the battery and check the charging status. This resets the power manager. I think one battery id bad, but you will need to test them one at a time. Good luck.

Iphone 4 shuts down after disconnecting from power cable
My iphone 4 completely shuts down after disconnecting from power cord. The screen goes blank. However, if I re-plug the power supply it turns on with the date and time changed but my battery status is 86%.
Reset, hold both Home and Power buttons for about 15 seconds until iPhone restarts. If everthing is OK, great. If not, connect to iTunes and try to Restore the Firmware. If still problems, make appointment with Apple Genius for Warranty service.

IBook shuts down after unplugging power adaper
Hello there...
My iBook G4 doesn't last for more than 10 minutes after I unplug the power adapter. I've checked some other posts and it looks like you need the information below before going any further. Any help on what I should do to remedy this problem?
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 1209
Remaining Capacity (mAh): 1207
Amperage (mA): 0
Voltage (mV): 16593
Cycle Count: 250
Thanks,
HagenHey Hagen,
I've got a brand new iBook 12" battery here in front of me. Just got it in the battery exchange program.
It was fully charged and I've been running it on battery for a bout 15 minutes.
Battery info:
Charge Remaining (mAh) 4136
Full charge capacity (mAh) 4400
Cycle count: 1
Condition: good
Amperage (mA): -1007
Voltage (mV): 11956
So that info that you gave us is w/ the iBook plugged in? The above was with it running on battery.
When this one is plugged in info changes to:
Amperage (mA): 1748
Voltage (mV): 12378
So you're battery seems really weak. The cycle count is pretty high and the capacity seems to be about 1/4 of new.
But run it on battery and give us that info again.
Li-Ion battery have an expected lifetime of 3-4 years whether you use them or not. Which surprised me.

Nano won't shut down after disconnect
I have a sleek black 4gb nano with software version 1.2 and the latest iTunes (ver. 7)
When I connect my iPod to charge/sync and then disconnect it, the iPod's power goes on and I can't turn it off!
I try holding in the play/pause button, but it doesn't work.
The only way of turning it off is by first playing a song and then turning it off while it is playing!
is this a common ver. 1.2 error, because I can't remember having that problem with the previous versions.No wories, iTunes 7.0.1.8 Solves this problem.

Computer Shuts Down After Removing All Screws and Putting Them Back
On the bottom of the laptop I removed most of the screws including the screws that allow you to remove the keyboard and most of the other screws too on the bottom. Why you may ask, no reason, just did it. I never had this problem ever until removed the screws and putting them back.
The computer only shuts down when the power cord is plugged in. Running off of the battery only I never have this problem.
Please note I have verified the following:
The computer only shuts down at random times only when the Power Cord is plugged into the computer and this never happened before until I removed the screws and put them back in.
I have tested with more than one thinkpad power cord to make sure
Tested with battery in the computer and removed from computer
My thought is maybe I missed putting in a screw on the bottom or maybe there is a ground screw I did not put in. Could my machine have an issue with not being grounded? I am not an electrician but who knows. Could there be something in the motherboard that a screw is missing in therer and not allowing grounding or other?
thanksYou should go get the Hardware Maintenance Manual for your unit and verify that it is properly assembled.

Computer shuts down after unplugging the power cord
My computer is showing a Plugged in, not charging message, but it is at 88%. When I unplug the charger from the computer to work somewhere else, the computer totally shuts down and will not power up unless the power charger is plugged in. I tried taking the battery out and leaving the cord connected and the computer started fine. How do I get the computer to stop shutting down after unplugging? Any help is greatly appreciated.
Sounds like battery #2 has a short. When the system detects a critically low battery, it is likely to devote all power to battery charge until the batery reaches 5% or so.

Mac book pro mid 2009 shuts down after a few hour of use and then is very difficult to reboot. Sometimes I have to wait hours, sometimes I have to repeatedly press the power button and then it will slowly start a little longer each press untill it completely boots. It has done this three times know. Each time I was watching a video.
Try running the Apple Hardware Test - sounds as if you've hardware issues.

When running on battery power, my MBP shuts down after 30 mins..please help
this has been happening for the last two weeks; whenever i run my MBP on battery, it goes blank/shuts down after about 30 mins...would start back on, but shut down even before the login screen comes! i checked the battery display under the laptop-it showed 3 green lights!! TIA!! i bought my MBP off the apple website last september!
With your symptoms, most likely, yes. If you have a 17" MBP, you are out of spec (based on Apple's specification of 80% health for 300 cycles). If you have a 15" MBP, you're in spec (84% health), but your symptoms indicate a problem (i.e. a defective battery). So, contact AppleCare!
You can't calibrate now. I asked because if a battery goes too long (150-220 cycles) without calibration, the "sudden loss of power" can result.
Hope this helps...
Graham, that's why I inquired about calibration, but with the OP's cycle count, that's not the issue. Also, FYI the "battery condition" information is part of System Profiler with Leopard; the OP lists Tiger, and did post all the information available under Tiger. -
Pavillion dv5 shuts down after ~5-10min on battery power?
11mo old laptop simply shuts down when running on battery power after only 5-10min after unplugging.
- Battery gauge shows fully-chaged when I unplug it
- No "low battery" warning or advice to plug in is given; it simply shuts off
If I try to turn it back on after it shuts down it will not power back on unless I plug the laptop back into the charger.
This never happens when plugged in to charger.
I know battery life can diminsh over time, but this came on all of a sudden; battery life was good (several hours) up until very recently. Now it just shuts down after a few minutes.
Appreciate any thoughts or advice - Thanks!Laptop batteries can and do suddenly go bad. If one or two cells die, they can actually leach power from the other cells. The Smart chip inside the battery can actually go bad and shut the battery down even if the cells have power. The warranty on the battery is (usually) one year and if yours is 11 months old you can likely get HP to ship a new battery to you without returning the whole machine to them.

MacBook Pro 17inch shuts down after power is pressed
Hello,
My MBP shuts down after I press power button.
It the boot process it goes as far as:
chime
grey screen
grey screen with apple logo
then shuts down completely (sometimes only chime etc.).
If it gets to the login screen, it works normally.
I did SMC and PRAM reset. I removed battery and tried to start it on power connected.
I reinstalled operating system and nothing seams to solve the problem.
I have read number of posts and tried all of the suggestions.
The most common suggested sources of the problem:
battery
graphics card
hard drive
Please let me know if someone was able to solve similar problem.
Thanks, TThe whole story doesn't make sense as anything but a hardware fault.
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Mac shuts down when 90% POWER and its PLUGGED IN!
I recently took over my husbands mac pro OS 10.4.11. At first, all was going well. Then I noticed one day, it shut down on me and I was like, that's weird, I had no warning. I did see other postings about this so it must be common or an issue with the battery. The thing is, its plugged in 100% of the time when I use it...if I do not have it plugged in, well, it shuts down after about 5mins...if that. I am not sure what is going on. Does anyone know (if it is the battery), roughly what a fix like this would cost? I read on other posts that you need the battery info, etc....this is what my mac says: Anyone have any idea just looking at this?? I greatly appreciate it!!!!!

For instance, it has been plugged in all day and my battery icon (at the top right) shows 98%...but the power cord (normally green light shows, is orange)...it just shut off on me about 5mins ago again. No warning, no programs saying they will close, just went black. No hibernation, etc...I had to push the "on" button to get it back on...It's so frustrating. Almost like it has had enough and goes off or like it's dying....So even though the battery shows fully charged, it still just shuts off....and I can be in the middle of typing or web surfing, etc...it doesn't happen when I just have it on but not using it (like a power saving thing)..it shuts off even when it is actually being used. I have no clue what to do.
Thanks so much for trying to help me out. I really appreciate it! -
MacBook shuts down after 2s of sleep
I've run out of ideas of how to fix a problem that started on the weekend.
It's an early 2009 2GHz MacBook running 10.6.7 with 5GB of ram.
The problem is that the laptop shuts down about 2 seconds after it goes to sleep.
Initially it was also shutting down after a minute of being left idle but that behaviour has stopped since I repaired the hard disk last night. It does however now beep (even if muted) and display the shutdown dialogue box after being left idle for a couple of minutes (it continues to give a prompt beep every couple of minutes, again even if muted).
Once shut down it won't respond to the power button unless I have disconnected both the power charger and battery for a few seconds. It will then restart from either the battery or power charger.
The shut down problem is the same with or without the battery onboard. Battery count is 163 and condition is reported as "normal" in Profiler.
I've tried starting from a fresh OS X install of both 10.6 and 10.5.6 on a USB drive but it still shuts down on sleep.
I've reset SMC, repaired permissions, repaired the disc (there were some errors that were repaired) and now run out of things to try.
The system.log shows the following when it shutdowns down while sleeping:
May 30 20:50:52 loginwindow[41]: loginwindow SleepWakeCallback WILL sleep
May 30 20:50:54 configd[14]: PMConnection mDNSResponder com.apple.powermanagement.applicationresponse.slowresponse 2047 ms
Any ideas?If I recall correctly, MacBooks go into a mode of sleep called Hibernate by default. In this mode, the contents of the memory are saved to disk when the sleep starts. You can tell if this is happening by looking at the light on the front. If it stays fully on for 10 seconds or so then the computer is hibernating, otherwise it is just asleep.
Anyway, to stop rambling - maybe you should try toggling between normal sleep and hibernate to see if that makes any difference. Follow the instructions on this page:

Hello my ps 2014 can not open it shuts down after 10-15 seconds. the old version run fine
Hello
my ps 2014 can not open it shuts down after 10-15 seconds. the old version run fineThere are several things you can do I understand.
1) Check the battery condition using a program like the widget iStatPro (free). If the battery health is less than 80% then Apple have a free replacement program for this.
2) Switch the machine off and disconnect the power supply. Remove the battery and leave out for several minutes - to allow complete discharge of all electronic components, I think. Then re-instal the battery, etc and restart. I'm not 100% clear on all steps in this procedure but it provides a reset which sometimes resolves problems at least temporarily.
3) Disconnect all peripherals and see how it works. One of these might be calling for more power than it should.
