Suddenly shutdown when the battery is lower than 6%

suddenly shutdown when the battery is lower than 6% (sometimes lower than 10%)and can not power on anymore, you need to plug the AC to trigger to power on the phone.

Your battery gauge needs to be recalibrated. When the phone goes off, charge for just a couple of minutes, then run the battery down all the way. If it shuts off above 1% charge again for a couple of minutes, then run down again. Repeat until it actually goes off at 1%. Then charge for 4 hours with the wall charger without using the phone.
To prevent this happening again, about once a month run the battery all the way down until the phone shuts off, then charge to 100% with a wall charger. (This is actually recommended in Apple's iPhone tips, but they don't say why to do it. The "why" is to recalibrate the battery gauge.)

Audio popping when battery run low. Help !!

Hi there,
I have a macbook pro 13" late 2011 with OSX Lion, 8 Gb Ram and 2,4 Ghz i5 cpu.
I'm a producer/composer so I use mt mac a lot for audio.
My problem is that whatever I'm doing, if I'm using ableton or maschine or logic, when battery is low and the low battery message appears on the screen,
my cpu meter goes very high (red) and it's impossible keep on working: audio starts popping and running slow so much that is impossible even understand what track is playing.
So when I start to charge it it comes back and starts working properly.
I don't understand why it happends only when the battery low message on the screen appears.
It happends even if I use vlc playing an mp3.
Any help please ???

Roblars,
As Csound1 said keep the battery charged, or better still, use the power supply.
I do production as well, and I think that Csound1 does as well,
Yes, I do.
I would not even think of working on any project on battery for more than :30m.
No power from battery= all kinds of artifacts and errors.
I never work on battery, performance is reduced.
Hi there

Solaris 8 in ultra 2 got panic and auto reboot when install Oracle software

Dear all,
I installed Solaris 8 by selecting 'Entire Solaris Software Group' and select 32 bit support only in an old ultra II machine. Then I tried to install Oracle 8.1.7 in the same machine but machine always got panic and started auto reboot when Oracle installed about 17% or 20% or even 70% (I tried install the minimum of Oracle).
What is the problem? Anyone can help?
Thanks in advance,
Vicky

I think you need to check the parameters like SHMMAX etc in /etc/system file as recommanded by oracle if not already added you need to add them .Oracle manuals have a list of these parameters and don't forget to reboot and boot with boot -r after adding these parameters.
Make sure you have sufficient memory or some patch recommanded by Oracle .

MBP shuts off by itself when battery is low

Just recently my MBP has started to shut itself off within 10 seconds of displaying the low battery warning. It's as if someone took the battery out of the computer. I can start up the computer fine after I plug it in, and once charged the battery will power the laptop just fine until it gets low again. The problem repeats itself when the battery gets low again. I've been on 10.5.3 less than a few days, and before I made the update I never had this problem. Any ideas as to what's causing this?

Try this: Shut down your computer, take out the battery and power cord and pres the power button for about 10 seconds. After that, reseat the battery (and power cord if necessary) and turn on the computer whilst holding down Command-Option-P-R. Wait until you hear the startup chime AT LEAST once after the initial chime. What you just did is a reset of SMC and pram.
After that calibrate the battery by fully charging it, use the computer on power supply for at least 2 hours. Then unplug it and use it off battery power until it completely runs down. Let it stand for at least 5 hours and plug it back in.
Hope this helps

Disable scrollbar when content is lower than viewport ?

Hi,
I have a vertical scrollbar always showed (JScrollPane.VERTICAL_SCROLLBAR_ALWAYS),
but I want it to be disabled when the content in the viewport is lower than the viewport's height.
Take for example Chrome browser in Windows: when u open up Google, the content of the page is quite low in height and the scrollbar in Chrome will be disabled. As soon as you have enough content on the page the scrollbar will be active.
How can I achieve this ?
Thanks

Hello,
It's not really a problem, I just realize it is a SWING limitation, (...)
Almost all app have this behaviour; it isn't really nice visually.I don't have Chrome, and haven't seen this behavior anywhere so far (but admittedly, I'm way behind in terms of GUI fashion).
The behavior that I'm used to (and that Swing designers apparently believed to be the norm too), is that a scrollbar disappears when the width of the view does not justify it ( SCROLLBAR_AS_NEEDED ). Using SCROLLBAR_ALWAYS implies that you want the scrollbar there, no matter whether the view's width deserves it. How the scrollbar looks in this case sounds like a Look and Feel choice instead (I only have oldish OSs, but maybe you know an Operating System where this behavior is the norm? In this case yes, it is a limitation of the corresponding Swing L&F).
maybe there was some workaround.Considering this is not in the OS LAF, this can be "manually coded", by listeneing to resizing events and accordingly changing the scrollbar's appearance.
Assuming the "disabled" scrollbar appearance is what you're after (no idea, it's just an example, if that doesn't suit your need you may do something else in the placeholder code), here is a, admittedly rather dense, workaround.
Notice how the vertical and horizontal scrollbar looks different (I only applied the workaround to that latter).

HP Pavilion g6 Notebook - Sudden shutdowns without warning when battery is low

My notebook is only ten months old. Within the last week, it started shutting down unexpectedly when the battery was low (but not at a critical level). If I try to restart it, there won't be a response until I plug in the adaptor cord. Usually there will be around 20% of my battery left when my computer is booted up after such a shutdown, so I don't think it's because of my battery being low. (Besides, when I've accidentally used my laptop until it has to hibernate, the light next to the port for the adapter cord usually blinks to tell me it's the battery.)
Initially I thought it was a problem with overheating, so I cleaned my vents and bought an external laptop cooler when it first shut down unexpectedly two weeks ago. However, the shutdowns have become more frequent since then. I've run the Memory Diagnostic Tool, the HP Battery Check, and updated my BIOS. No problems have come up; in fact, everything seems to be running perfectly. I also ran AVG and Malwarebytes Anti-Malware. No problems there either.
What could be the problem? Thanks for any help!
Product name: HP Pavilion g6 Notebook PC
Product number: A1J18AV
Windows 7 Home Premium 64-bit Service Pack 1

Mines started doing exactly the same! Its just 12 months old though and hardly ever gives me a low battery warning. Then it will turn off without shutting down the proper way. When I plug in and turn back on, the battery says its at 20-25%
Is there actually a solution to this and whats causing it?..because if it's the battery then **bleep**..they don't last long.

Memory full error message when battery is low

(Ive done a check and cant find anything similar)
I have an E71 and keep getting "memory full" error messages ONLY when the battery is low. I have 109 free memory out of 119, and when I connect to the USB it says it doesnt recognise it, so I cant save anything to computer, not that there is anything on there.
The problem is, because it says MEMORY FULL, it wont recharge, even when the charger is plugged in and switched on. Which means basically the phone is useless.
I think this has to be a softwear problem and not a Ive-misused-it-problem because the MEMORY FULL ! message comes up only with low battery.

Hi have you checked if your 920 memory is full via the Settings > Phone Storage to ensure that your 920 has got enough memory? Otherwise, have you checked your car stereo itself (is it a model that has built-in flash storage or hard drive storage) for its memory capacity?

Alert message when battery is low?

This is only a minor problem really, but it's irritating all the same. As well as getting the usual visual message when my battery's low, when another 2 or 3% has gone I also get an audio alert too (saying "Alert!" or "Attention!"). I've turned VoiceOver off, I have Speakable Items off and the "Announce when alerts are displayed" (in System Preferences --> Speech) box is unchecked. The battery being low is also the only thing I'm alerted to in this way.
Any help would be appreciated in how to fix this.

Is your cradle plugged in to AC power or a USB port? If the charge is very low on the phone, it needs to be plugged in to an AC power source to charge.

WRT54GS v5.1 auto reboot when wireless device connects

Hi,
I'm using the linksys WRT54GS wireless router v5.1
Current Firmware version v1.50.9, Sep. 14, 2006
The problem that I have is that everytime a new device connects to the Router wirelessly, the router reboots itself.
After the reboot, everything seems to be working fine. This becomes quite annoying when it comes to gaming and another family member turns on their laptop and then I get disconnected by the router because they are connecting.
What I have done upto now is reset the router after doing the FirmWare Version update and the problem still occurs. (The problem was still there even before I had done a FirmWare Update.)
Is there a way to solve this problem? because I have read about a few other problems just like mine on the forums and they don't seem to have been resolved.
Or will I have to go back to PCWORLD to see if I can get a refund / replacement?

I do not see a "keep alive" option. I use the Automatic Configuration - DHCP because I have connected, a CABLE MODEM provided by my cable provider Telewest Blueyonder
The router just reboots when the wireless laptops connect. The wired desktop (this PC) loses connection as it is rebooting and regains connection after the reboot. Then both PC and Laptop work fine.

Computer Shuts Down When Battery Gets Low

I have a few interconnected issues and one peripheral issue:
1) When battery charge gets down to between 20% and 10%, by MacBook shuts off. It doesn't go to sleep. It just shuts off.
2) Battery loses charge quickly (I get about 1.5 hours of use out of it, which is no good for a machine that's a year old, right?)
3) I think the machine runs to hot and fan gets too loud.
The above all occur when set for "better battery life" and when doing light web surfing, ichat, and playing music in itunes. I did the firmware update and no change to these problems.
Then there's this...
4) Distorted screen, specifically horizontal green lines, when trying to watch a DVD through FrontRow.
Anyone experience this? I just am curious what to expect before I take the machine in...again (it was treated for RSD).
MacBook Mac OS X (10.4.6)

I'm running on battery now.. saving all my work diligently pretty much every minute on the minute... currently 1hr 42mins remaining of battery life - so it says.
This compleatly unnanounced shut-down has happened twice to me now, and it's very disconcerting. This is the only problem I've ever had with my MacBook (bought it August last year) and is annoying as I KNOW it was this 'update' is responsible. I lost about 40 mins of work because of this yesterday and am pretty annoyed about it frankly. My battery seemed fine before hand - I actually was typing away happily on it in the back of a four hour car journey just last week, eeking out the charge by turing the screen right down etc. SURELY if this is known, and is obviously software/firmware created, Apple can offer a similar patch to correct it??
I'm in the UK and a day-trip away from any Apple Store. Do I have to phone Apple and ask for a replacement battery? Is that how it works (like I said - I've never had technical difficulties with my MacBook previously). I searched the site and found this number: 0870 876 0753, I think that's right. What should I have ready on the phone?
REALLY hope this can get sorted soon as I can't really trust the machine at the moment without it being plugged in, making taking it out anywhere (which is why I got it - and loved it) pretty redundant.

M2 Not Charging when Battery is Low

Keep us updated.

I recently took delivery of my M2 and am generally very pleased with it. However, I'm encountering a problem when the battery charge is low. It doesn't seem to take charge when I plug it in. It recognises that a charger is connected, as in tries to go into night mode and stops showing the "Connect your charger" message, but it doesn't actually CHARGE - no notification icon or light, battery keeps draining. Ultimately, the battery goes dead and the phone shuts down.Then, as "expected", it takes a few moments to show that it is charging, and eventually the light comes on and charge happens. This seems to only happen when the charge is low before I plug it in. If there is more than minimal charge, then it charges OK. It's a bit of a problem that I can't charge the phone when the charge is low..... Any ideas?

IPad 3G no longer detected by iTunes (Win Vista), only charging when battery V. Low

This appears to be a software issue: my iPad 3G (32GB) is not detected by iTunes (yet my iPhone is), nor by Windows Vista. Furthermore, it does not charge from the wall charger until it shuts down in low battery, and only charges to 2%, after which it switches on again. Tried switching off and charging, which only causes it to switch back on again. Also tried cold resetting, but problem persists. Was working fine previously, no updates, additions or subtractions were made to either PC OS, iPad or iTunes immediately before problem started... and there doesn't seem to be any mention of this on the internets (including this forum). Any suggestions?

Soft boot, hold down top button and middle bottom button at the same time, with the iPhone connected to your computer and iTunes will recognize the phone on reboot.

IPhone 3G won't charge from car adapter when battery is low

I regularly use my Griffin car charger to charge my iPhone 3G. It seems to work well most of the time.
When my iPhone 3G is very low on battery charge, I discovered that the the iPhone will no longer charge via the car charger. Only way I can recharge the iPhone is via the cable connected directly to my computer or via the wall adapter.
Is this a normal behavior? Very unfortunate if it is since forcing a mobile user to connect to a wall outlet or a computer makes no sense.

Copied from my previous post in this thread.
I know if the iPhone's internal temperature if over a designated temp, you can't charge the battery until the internal temp has been reduced. This is protection for the battery and internal components since charging increases the internal temp.
When this occurs, the charging indicator will switch to showing as being fully charged.
Are you using a case?
Charging increases the internal temp of the iPhone, and using GPS will also increase the internal temp of the iPhone. Combined must have increased the internal temp of your iPhone past the designated temp when charging stops. Using a case can prevent heat from being dissipated properly.

When battery is low, doesn't want to charge?

So, sometimes, and it seems to happen more when the battery is already below 20 or 10%, I put it on the charger over night, and the next morning it's displaying the battery on the screen still at red - (I guess when things are going well during a recharge, the screen shuts off)
At first I thought it was a cheap retractable synch cord I was using, but this has happened twice now with the official white cradle as well - and I took extra care to make sure it was properly seated before I went to sleep.
Luckily, putting it on a Altec-Lansing pair of speakers lets it charge most of the way in a hurry... but what's going on with just putting a low battery phone on the cradle??

Is your cradle plugged in to AC power or a USB port? If the charge is very low on the phone, it needs to be plugged in to an AC power source to charge.
