Fried motherboard, battery still charging?
It was almost 12 days ago when I accidentally spilled hot water all over my keyboard and the computer automatically shut down. I have already tried to save it by keeping it in a box of rice and silica packs, but after a week it still would not turn on. My motherboard probably fried from the water, as my brother reported that he saw the marks when he opened the macbook that I bought last year.
Out of curiosity, I plugged in my power cord and strange enough, the green light still turned on. It does seem a bit faint though, but I just wanted to know if there's still hope of it coming back to life if I continue to wait it out? My warranty is done, but I know Apple wouldn't fix a water spill under warranty anyways.
Hi
I just wanted to know if there's still hope of it coming back to life if I continue to wait it out?
Rather unlikely, I'd say... the charging part (even assuming it's working normally) is a separate little board on (at least some) mbp's.
Liquid inside, even just water, often needs dismantling/cleaning rather than just drying out, pre-suppsoing no actual damage to components.
On the upside, such as there is - parts fetch (sometimes) silly amounts on ebay & elsewhere - you've got perhaps a good battery, top & bottom case, lid, drives & fans maybe, display, keys, etc etc
Ok, it needs dismantling to get the best amount, but buying a couple of screwdrivers & watching an iFixit video could get you a few hundred $. Even if you don't want to strip it, someone'll buy it for spares & do the same thing.

New 12" PBook, battery 100% charged plug orange, charger very hot. Why?
New (refurb) 12" PowerBook arrived three days ago.
This evening I noticed, for the first time, that the indicator in the menu bar indicated that the battery was 100% charged. But the plug stayed orange.
After about a hour in this condition I also noticed that the charger was extremely hot. The charger for my G3 iBook never got so hot. I unplugged the PowerBook.
Anyone know what's going on here?
12" PowerBook 1.5GHz Mac OS X (10.3.9)
iBook 900G3 Mac OS X (10.3.9)sounds like a malfunction with the adapter...if u unplug adapter does the battery still charge computer and show a high charge ro does it slip as soon as u unplug it?

5G video, Replaced new battery,still wont charge,here's what ive done
My english isnt very well, hope u understand most of it. If you are impatient with my story you could just scroll down to the bottom,
Ok, so, my 60gb 5g ipod video is about 2yrs old. The drain battery thing starts happening a year ago.
With a full charge(as the screen said), once it's unplug from power source, it dies within 1 mins. so, i bought a new battery on ebay(hang on dont say the battery is bad, keep reading) put it in. That slightly improved, with makes it play for about 2hrs with a full charge. Not long after the replacement of this new battery, the ipod starts draining,and die quick again.
I decided to give it one more chance, and got a more expensive battery from ebay again.
after i replaced the battery, plug it into charge, it already says fully charged. At first i thought maybe it comes charged. so i unplug it. but the battery meter reads low, with like maybe 5% left.
That's when i realize, the problem is not the battery but the ipod.
I've read hundreds and hundreds of thread online. doesn't really help. I did all those reset
, disk mode and restore. The ipod still thinks the battery is charged and wont let juice pass on to the battery. At last, I've found a 13.1.2.1 firmware, and downgraded it from a 1.3, and see how it goes. Sadly, nothing changed.
@@@@@@@@@@ IF you are impatient, JUST read this part @@@@@@@@@@@@@@@@@
I took the NEW battery out, found a 3.7v charger, and charge it externally / manually.
put it back in, the battery meter( the one of right top corner, while unplug) reads a 80% charge)
so, this proves that the battery is 100% GOOD ! when i plug it in, the ipod still thinks the battery is charged and wont charge it.
Here's my conclusion. There's a problem with the motherboard/mainboard, either the chip that prohibits battery from over charging is out, or there is something wrong with the socket.
My solution(which I haven't done yet) is drill a hole on the back plate close the the battery location, Charge it from the outside, with wires directly connect to the battery(if u rip those plastic tape carefully, u would see the +/- connectors).
Cost: 3.7v charged, should be less than $15 or just find a unused cell phone charged.
or just mod your ipod wall charged.
Connectors between the wires to the battery and the external charger could be find it
Wal-mart, Ace, and many other store. for Wal-Mart they are usually in the Auto section. Should be around $5
So, the whole fix for mine is just $10, since i mod my own ipod charged. and the $5 tips at a auto shop for the guy that drill the hole for me.
This saves me $90 from buying a used 60gb ipod from ebay, and around $300-$400 from a new one at apple.
After all, I post this because i dislike the way apple treat their costumers, they simply wants you to buy a new one instead of helping you. I've read lots and lots of stories about how people are unhappy, upset and even angry with apple. I'm one of the millions.by the way, replacing the motherboard cost about $55 if u do it yourself, which i would rather buy a new one if thats the case.
and sorry that i didnt do a proof reading, of which lots of error in my post. -
I brought an iPod off eBay, second hand a few weeks ago. The first week I had it everything was working fine. Then suddenly when I plugged it in to charge the battery logo didn't appear, so I left it overnight and it still charged but there was still no logo. And now when I plug it in to connect to my iTunes on my computer, it isn't showing up on the left hand side where it should. I have tried restoring the iPod twice and using different cables and no change was made, what should I do?

How come my ipad mini battery percentage drop even though is still charging with the charger?
I just bought my ipad mini two weeks ago. Just curious how come my battery percentage will drop even though I am still charging it. And this happen twice. I never do anything with the ipad when charging as I left it to charge while i went to sleep.
There must be a loose connection somewhere; check all your connection points or try another wall socket.
If it still doesn't work, try another cable and charger. -
Is it safe for your iphone battery to use your iphone 5 while it's still charging??
so ive heard multiple times from people with pretty much experience at using mobile devices that it's not good for the batteries of your mobile devices to use them whie theyre still charging as doing so can gradually damage the batteries and reduce the overall battery lifetime. Is the claim true tho and does it apply to iphone 5 as well??? will my iphone 5 battery be damaged in the long run if I keep often operating it while it's still charging?? is that action really bad and adverse for the health and condition of the iphone 5 battery and its lifetime?? plz for those who know , clarify all this . THNX
This is no problem at all.
You can use it all you like while it is plugged in.
No effect at all. -
I have an iphone that has stopped charging. I have purchased a new battery and charger for it but it is still not charging. Does anyone know how i can fix this?
That pretty much eliminates all the user-serviceable parts the phone has.
When you say you purchased a new battery, I'll assume that it included the installation and you did not go fiddling with the nanoscrews and such. So it's got to have some sort of warranty that the part is good and it is time to take it back for service. -
HT3964 SMC Reset and Battery still not charging
Few months ago my battery wont charge, I performed a SMC Reset and the battery gets to work fine again. Recently the battery is not charging again right after a long period of inactivity when the macbook air was not plugged or use it for months. Now is working only if it´s plugged to the electrical socket.
I have been reset the SMC on my macbook air but still my battery is not charging, it is 0% and when I disconnect the magsafe it will turn off. What else should I do?sketchbook0918 wrote:

I will be traveling to Rome and Paris and I'm concerned about frying my iPad when charging. Will I need a converter/adapter when charging or will I just use an adapter?
what RBRY says. Look at the fine print on your power brick. It says 100v-240v. This means it can handle world wattage.....both the us 110 and the UK/and other places 220. Anything that displays that range works anywhere in the world with the right plug adapter.
You can get plug adapters at walgreens, walmart, target, kmart, best buy, office max, office depot.....almost any major retailer. Look in the travel/luggage area.
Do some googling and find out what Italian plugs look like or you can simply find a kit that is a 'world wide' kit. -
SMC Reset and Macbook Pro Battery still not charging
Hi, I bought a new Macbook Pro the Christmas before last (2 years ago) and unfortunately didn't remember to buy the AppleCare. (Didn't have the money to purchase it as I was buying the computer) Anyway, today my charger decided to stop recharging the battery. The battery icon says the battery is charging but the LED light on the charger is not on at all and when I click on the battery status it says "Battery is Not Charging." I've already tried the usual troubleshooting and Resetting the SMC but it didn't work. I also checked the status on the battery and my computer said it was Normal. What else can I do? I really need this laptop for college and the battery has to be usable.
If available, try a different charger.
What does System Report>Power say under AC CHARGER INFORMATION?

Fried my battery with variable voltage charger... new battery; wont work
so i plugged my ipod into one of those cheesy charge anything car adapters when it was on the wrong voltage setting. only took a few seconds before my ipod died, permanently... so i ordered a replacement battery and installed it... but for some reason it wont take a charge when i plug it into my comp... i figured the new battery was faulty so i got sneaky and popped the case off my girlfriends ipod and plugged my battery into it and connected it to my computer, and the **** thing turned on... so after my new battery was charged i took it out of my girlfriends and put it back into mine and it turned on... i was stoked, until i plugged it into my comp it said "battery low please connect to power source", beeped at me a few times and shut off. the battery has a full charge but it wont connect thru the usb cord to my computer or a wall charger... why cant my ipod connect anymore did i fry some internal circuitry as well as the battery... please offer any advice you might have im stumped and i cant just pull the case of my girlfriends ipod everytime i need a charge.
I assume by wrong voltage setting, you mean you had it set too high? Was it connected to your iPod through a USB connection?

BlackBerry PlayBook battery power charge, discharge characteristics, and guidance on extending battery life
KB27705
Overview
The BlackBerry PlayBook may come to a power state where it is unable to power on; a Yellow LED may flash in a sequence of 5 flashes, the BlackBerry PlayBook may boot up to the BlackBerry PlayBook Logo and then power off, may not power on at all.
Discharge behavior under normal use:
Under normal active use, a battery drained to 10% will cause the device to prompt the BlackBerry PlayBook user (notification and audible beep)
Without connecting a charger the device will automatically shut down at 3.53V (0%)
Pressing the power button may allow successful boot, but it will turn off again very quickly
Discharge behavior under no use:
A device left unused but in ‘Stand By’ will warn the BlackBerry PlayBook user at 10% (notification and audible beep)
The warning may not be noticed and the device will go back to ‘Stand By’
Letting the device drain in standby mode drains the battery slower, but more completely
Device will still shut off at 3.53V (0%), but it less likely to successfully boot afterwards
Discharge behavior under 3.53V (0%):
If the device is left to shutoff, the battery will continue to drain below 3.53V due to quiescent current draw from the motherboard and the battery fuel gauge
With the battery between 2.7V-3.53V, pressing the power button causes the LED to flash a pattern (1 solid red light followed by 5 yellow blinks) to indicate low battery (PlayBook Tablet OS version 1.0.5, and above)
Below 2.7V there is no activity, or LED pattern displayed
Charge Behaviour:
The provided charger should be used to charge the device. The optional 12 volt rapid charger is may reduce charging times
to approximately 3 to 4 hrs. Standard Blackberry smartphone chargers, other AC adapter USB chargers, or computer USB ports
are not recommended for the sole purpose of charging the PlayBook as with these methods it may take more that 12 hours to
charge the BlackBerry Playbook.
If the battery voltage is below 3.53V(0%) then the charging behaviour is dependent on the software version. The charging code will limit the charging current to under 400 milliamps, during which time, it may take an hour to reach 3.53 Volts. Once the battery voltage rises past 3.53 volts, then "high-rate" charging will start. If, after charging the Tablet for 4 to 6 hours still does not result in LED activity, attempt to force power on the BlackBerry Playbook by pressing and holding only the Power Button for only 20 seconds.
Prior to BlackBerry Tablet OS 1.0.5:
A BlackBerry PlayBook will never charge while powered off in BlackBerry Tablet OS versions prior to 1.0.5.
The device will show a red light when the charger is connected and then nothing more
Repeated connection of the charger can recover the device in some instances.
Once the battery voltage rises above 3.53V the system will boot and the UI will show charging
Starting in BlackBerry Tablet OS 1.0.5:
The device will show a solid red LED, followed by a solid yellow LED as the device boots into charging mode. This is followed by a yellow pulsating LED indicating charging in progress.
The time span between the red and yellow lights can be as long as 45 seconds as the device boots into charging mode.
Once the yellow LED illuminates, the device can be started, but it is advisable to let it charge for at least 3.5 hours to achieve a sufficient charge.
The device will show a solid green LED once the device is fully charged.
Starting in BlackBerry Tablet OS 2.0.1:
Once the yellow LED begins pulsating indicating charging mode, if the BlackBerry PlayBook is disconnected from the charger, the following graphic will be displayed on the screen, indicating charging is not complete, and to reconnect the power source. The graphic will be displayed for 20 seconds before the BlackBerry® PlayBook powers off if the power source is not reconnected. The same graphic will also be displayed if the BlackBerry PlayBook is turned on and there is not sufficient power to perform the boot process.
If the BlackBerry PlayBook is plugged into a power source, and the power button is pressed to power on the device, the following graphic will be displayed if there is not sufficient power to perform the boot process. If this occurs, the BlackBerry PlayBook should be left plugged in to gain enough charge to boot.
Additional Information
Turning off the BlackBerry PlayBook and using standby mode.
Checking the battery power levelOn the status bar, tap the battery icon. When the battery power level is low, the BlackBerry PlayBook tablet will display a notification.
Enter standby modePress the Power button on the top of the BlackBerry PlayBook..
Exit standby modeSwipe down from the top frame to the bottom frame
Turn off the BlackBerry PlayBookPress and hold the Power button. Tap Shut Down.
To extend the BlackBerry PlayBook battery life, charge it regularly, close unused applications and keep the BlackBerry Playbook out of the sun and other hot places. The following may also be used to extend battery life:
Dim the screenOn the status bar, tap the Options icon (a gear), select the Screen tab and change the Brightness setting
Turn off the screen automaticallyOn the status bar, tap the Options icon, select the Screen tab and change the Backlight Time-out field
Enter standby mode automaticallyOn the status bar, tap the Options icon, select the Screen tab and change the Standby Time-out field
Turn off Wi-Fi when not in useOn the status bar, tap the Wireless icon and set the Wi-Fi switch to Off
Turn off Bluetooth connectivity when not in use
On the status bar, tap the Bluetooth icon and set the Bluetooth switch to Off
Pause apps when you show the home screen or switch between apps On the status bar, tap the Options icon, select the General tab and set the Application Behavior switch to Paused
With the upgrade to PlayBook OS 2.1.0.1032 the following message may be displayed when connecting the Playbook to a PC using the micro-USB cable:
Unable to charge battery with connected source
This message is displayed because the voltage provided is insufficient for charging. The USB voltage is limited to 384mA even if the maximum tolerance is 500mA. The voltage is limited to 384mA by design to avoid violating the USB specification which states USB devices cannot draw more than 500mA from the USB port.TroyTempest wrote:

Pavilion dv6629us battery not charging
About a week and a half ago my laptop stopped charging my battery, it detects the battery and it says is charging but its not actually charging the battery. I did a BIOS update and still the same problem, I also turned off the computer to see if the battery would charge when the computer was off but no luck. I tried to charge the battery on Ubuntu and on Windows 7 and it does the same thing. I ran the HP Battery Check and it tells me:
An error was encountered trying to access the battery. Please reinsert the battery and the AC adapter to retest the battery.
I have a brand new battery so I know is not the battery. I removed the battery and reinserted it and it still does the same thing. When I click on the bottom right corner battery icon it says that is plugged in and charging. Whats wrong?
Here are some screenshots:

In Ubuntu Linux I get this battery status on the Terminal:

1) Remove your battery,
2) Unplug your power cord from the notebook,
3) Push the power button for 15 seconds (if necessary you can hold down for 1 minute),
4) Plug the power cord into the notebook,
5) If the power led is on, your power adapter is probably working,
6) Push the power button,
7) If the computer powers on, your power adapter is probably working ( it's more certain than before),
8) Try to use the computer,
9) After Windows finished the entire start up process, you must insert the battery,
10) It's expected that the battery icon shows charging.
If it happens to you, therefore the problem is in the motherboard. The exact point it is in the ICC responsible for check and control the status of the battery. Up to know I don't know where is located the fault ICC. This fault ICC is a Voltage Comparator, usually it is an Operational Amplifier.
If you remove the powerplug the computer will start to drain the battery until the end, but if you reinsert the powerplug the computer WILL NOT detect, and it will continue to drain the battery until the end.
If you remove the battery with the powerplug inserted, the computer will turn off, cause it doesn´t recognize the power source from the cordplug.
Remove the power plug, insert it again without the battery and the computer must be able to turn on.
If you turn on the computer, and after this you insert the battery than the computer will start to charge the battery.
Resume:
A) To charge the battery you must insert the battery after the computer it is on.
B) To use the battery power you must disconnect the power cord, but you won't be able to charge it until you turn off the computer and remove the battery, and to follow the step A.
I verified that the problem happens to all DV6000 ( DV60xx ), DV6100 ( DV61xx ), DV6200 ( DV62xx ), DV6300 ( DV63xx ), DV6400 ( DV64xx )and DV6500 ( DV65xx ) series.
My case is a HP Pavilion DV6104eu, that I bought in UK.
