Dv6108nr Won't run on battery (blinking charge light)

I have a dv6108nr (it doesn't have the nVidia chipset - so it's likely not a chipset issue) that will not recognize any batteries - even batteries that work in other systems.
If I run the battery check, it shows no battery detected. If I pull the cord, it will run for about 30 seconds and then the BIOS must notify the system that the battery is drained and it shuts off. The light flashes constantly even when the system is off if I have a battery installed.
Any ideas on what parts to swap out? I thought of maybe swapping the DC jack board. I've got tons of spare parts for these things as I have two other completely failed dv6000 because of the nVidia fiasco. My other theory is that HP is being unscrupulous with their BIOS and making it deny any batteries older than a few years.
Thanks in advance.

Hmm.. I just took the whole laptop apart and when I had it apart, it was actually working on battery. I'm thinking possibly the motherboard was moving when you'd put a battery in because the one spot for a screw was broken out.
I've glued that now and everything seems good.
Also, in case anyone is curious, the dv6108nr (which originally shipped with a Core Solo) can be upgraded easily to a Core 2 Duo. I threw in a spare 1.73 Core 2 Duo and it's running like a champ. I also installed a screen with a web camera, and that works too.

Power Adapter Does Not Charge the Battery and Charge Light Is On?

Power Adapter Does Not Charge the Battery and Charge Light Is On?
My power adapter doesn't charge my computer anymore. however the charge light is on.
Please help my battery is draining fas

So, with your power adaptor connected not only does the battery not charge but the powerbook is not running on ac power. Then I guess the power adaptor is faulty. In as much as you've verified this with a known good one a new one is in order. Try yours in another powerbook to make sure.

My macbook black shutdown during a thunder storm , what do i need to? it won't turn on and the charger light is not on green or on at all..have i fried it?

Most likely.
You can try to boot from the Install DVD for your Mac and run AHT from there if it boots.
If not it sounds like it is time to take it to Apple for repair.

Battery stopped charging; won't run from battery

A couple of days ago, my computer stopped running from battery, and stopped charging the battery. I can see that the level is 67%, but that never goes up, and it shuts down if I unplug the power adapter.
Here is XBattery info:
Installed: Yes
Charging: No
Charger: Yes
Battery%: 67
Max. cap: 4.400Ah
Curr. cap: 2.271Ah
Charge: 1.534Ah
Voltage: 11.850V
Amperage: 0
Cycles: 680
Flags: 41000005
Anyone know how I can fix this?

I have the same issue with my Powerbook G4 15" Aluminum (battery not charging and clock not retaining date and time). A 3rd party warranty company is trying to say it's the rechargable battery but I think it's something to do wit hthe small battery located on a daughter board on the motherboard. Can anyone verify this or does this sound like a totally different issue?
The battery was replaced under the recall less than a year ago.
Thanks,
Bob

Dv7 Laptop won't run on battery

Laptop Data&colon;
[Image Removed]
Upon unplugging my laptop last night, it simply shut off, and since won't run off of the battery. It seems like the battery isn't connecting to the motherboard, but I ran a test in the support assistant that gives me this:
[Image Removed]
Is one of the cells dead, and that is why it isn't working, or could it still be failure to connect to the motherboard?
I have another battery, but unfortunately not currently with me.
The battery also won't charge past 86%, but again, I'm unsure of the cause. I left it out overnight and long held the power this morning to no avail as well.
Any help is appriciated. Thanks.

I understand your notebook battery no longer powers the notebook and the battery test has failed.
Reviewing the battery test, it looks like the battery (when fully charged) is only holding about 35% of the original charge. This means that the battery life wont' last very long as it will drain much faster. This is the most likely reason that the battery is no longer functioning is that it has reached the end of its usage. The battery test requires the battery to interface with the motherboard for it to test the battery, so I don't find the motherboard very likely at this point since the test was able to detect the battery.
You stated you have another battery to try. Try using that battery at your convenience to see if it can power up the notebook before purchasing a new battery. Should you proceed with a new battery, the replacement part number should be listed on the current battery.
Let me know if this answered your question.

Brand new macbook won't run off battery, only when plugged in

I just go my new macbook last week and being new to mac computers, I didn't realize that it won't run from just the battery power until last night. The battery light shows it's fully charged. If i'm working with it plugged in and it becomes unplugged, it shuts down and when I reconnect the power cord, it resumes from the same webpage or whatever I was last working on. I opened up the battery compartment and removed the battery and then held the power button for 5 seconds, but that didn't fix the problem. Does anyone know what I might try or if something needs to be set up in order to run off the battery? Thanks! Leigh

Hello leighdk,
Welcome to Apple Discussions!
You can by all means take some good advise from the people on this board in response to you problem.
But here is the best advise, especially since you're new to Mac.
Call Apple Care or take it back to the store and have them check it out. It is under warranty. You have 14 days from the date of purchase to return the Mac for a completely different or give it back because you do not like it. they may try to charge you a restocking fee but this should not be the case since there is an issue with you machine.
Call Apple, see what they say... Then if you can't get it resolved then post back and maybe we can give you some sound advise.

Powerbook Ti Gig Ethernet won't run on battery

After killing a brand new battery, I opened my TiBook and found that the battery connector was loose. Tightened that down and , while I was in there, replaced the PRAM/Battery, but the computer still won't run on the battery. Bought another battery, and it recognizes a battery is there, and reports that it's 76% full, and the power connector is orange, and the computer reports it's calculating the time until full. But it never is able to calculate a time, and if you disconnect the power, the computer immediately shuts down.
Have reset PMU, NVRAM, PRAM, etc. etc., no change in symptoms.
Any other suggestions??

Hmmm. OK, I withdraw the previous suggestion. Let's assume the battery is OK. But clearly, although the Powerbook "sees" it, and therefore it is at least partly connected to the Powerbook, it isn't able to deliver power to the machine in whatever way is necessary to make the machine run. Because you've already had occasion to tinker with the battery connector, I suspect there may still be a fault there: one bad contact, a broken wire, or something similar. How about diving back in and making sure all the battery contacts inside the compartment are clean and undamaged, and that the connector from the battery to the logic board is securely seated.
If that investigation yields no clues and the issue remains, you may have a faulty Power Management Unit on the logic board. I doubt that a faulty AC adapter or a faulty DC-in card (the other two components of the charging and power systems) could prevent a healthy Powerbook from running on battery power with a healthy new battery in place.
I'm not sure how thoroughly, if at all, the Apple Hardware Test disc that came with your machine is able to test the power management system. Try running it and see whether anything shows up. Post back with results.

MBP won't run on battery

As of a couple days ago, my MacBook Pro won't run off its battery. When I press the button, all the battery lights light up, indicating a full charge. But the computer won't turn on. Only when I plug in the power adapter does it work. If I pull out the adapter when the computer is on, it shuts off.
Yesterday, I noticed something peculiar. The light in front, which normally pulses when the computer is in sleep mode, was sort of half-pulsing. It would slowly fade on, then immediately flick off. Not sure if this is an indication of anything.
Is this definitely a hardware problem? I have an appointment to see a Genius tomorrow, but I'm wondering if there's something I can do on my own first.
Thanks.

PB won't run on battery

I have tried everything and been to the genius bar, they can't solve either.. I have new apple battery, have passed all hardware ans software test, even the extended apple tech's test. all passed.. PB 15" 1.5G bt2.. won't power up on battery, shuts down if ac plug is pulled. sometimes it won't power up at all (w/a/c) until I re-set the pram by holding down power button 5 sec.. all indications are to the Pram battery which I replaced w/a used one.. it worked for about a day and now back to the same..do I need another Pram batt? I won't pay apples service prices because I have seen what it takes to change the pram, I could do it in 15 minutes.. but Apple will not sell me a new pram over the counter. Not sure if i should buy one on line for 80.00 or not.. I may have to sell and get a new(used) Imac or something. I really love this PB and don't like the macbook pro, mostly for the price.
any resolutions out there? thanks, Brad

The Apple hardware test doesn't test the charging circuit ... there are only 4 components to the charging/power circuit: Power adapter, DC-in card, battery, and logic board. Assuming the power adapter is good (Apple store should have confirmed that) and the battery is good (when you push the button on the back the 5 LEDs light up?) .... does the power adapter charge the battery when both are in use in the system? A DC-in card problem usually manifests itself by not charging the battery and/or not running on a/c. If the battery is charging and as you said it runs on a/c, the DC-in card is probably OK. Before you get excited about the logic board, since it seems that you had some success with a used PRAM battery, go buy one from ifixit.com or pbparts.com. If that doesn't cure it, then it's likely there's a logic board problem. It's been reported that Apple offers a fix everything service for $350 and up, which is a price performer if you need a new logic board (actually a refurbished board), or you can buy a used one and install it yourself.

IBook won't run on battery

Hi Folks
Wondering if someone can point me in the right direction here. I have an iBook G3 900 mhz model that I just replace the logic board in (video issue). The ibook runs great now, but all of a sudden it won't work with out the power adapter plugged in. I thought maybe the battery went bad, but I checked it in my other iBook and it is fine.
I bought the Logic board at a discount because it had a missing plug in connector, which is the one that connects from the Logic board to the power button. I soldered it back on and powered up the Laptop fine. and it even worked with just the battery for a short while, but now only works with the adapter. Should I open it up and re solder the connection, or is this another issue?
Thanks
Don

Hey Don,
I have an iBook G3 900 mhz model that I just replace the logic board in (video issue).
Just curious. Did the GPU chip die? or was it the BGA issue? I repair and donate iBooks to inner city school teachers.
it had a missing plug in connector, which is the one that connects from the Logic board to the power button. I soldered it back on and powered up the Laptop fine.
Wow good job! That's not easy to do. BTW that plug would have nothing to do with the not running on battery problem. It's part of the "soft start" circuit.
This is from the service manual for the 900:
"The computer runs when plugged into a wall outlet but not on battery power
1. Reseat battery to verify battery is seated correctly with battery lock engaged.
2. Try known-good charged battery.
3. Reset the power manager by pressing the key combination Control-Option-Shiftpower.
Warning: Make sure you do not hold down the "fn" key when resetting the
power manager.
Warning: Resetting the power manager will permanently remove a RAM disk, if
present, and all of its contents. You will also need to reset the date and time
(using the Date & Time control panel).
4. Replace logic board."
That "power manager" they speak of is a PMU 99 which I believe is CMOS and very sensitive to static charges.

G560 won't run on battery

Facts:
laptop under a year old
lightly used
running fine on battery yesterday
battery meter shows 99% charged
What happened:
Using laptop last night on battery, hit 7% and I plugged it in. Finished what I was doing and shut down windows applied critical updates. This morning unplug laptiop and try to turn it on...nothing. Plugged it in and it started. Tried a couple times disconnecting battery and reinserted, battery meter working, shows charged just won't work on battery. Tried to roll back to previous restore point, as I didn't know if it was windows related. Still nothing. Read to leave it unplugged for a full minute...nothing. Any ideas?
Again the battery is not old or worn out, it held a multi hour charge yesterday.
Thanks

take a look at the thread below first. if it doesn't work, you'll need battery replacement.

PB 1400cs won't run on battery power

I've got a 1400cs, purchased second-hand, and it seems to have a problem running on batteries. Even with a new battery, it doesn't want to run on battery power. `Runs fine on AC power, though!
What could cause this? What are my options for inexpensive repair on this problem?

Keith,
I also have a 1400 with the original battery which will not even run the 'book for a second when I unplug the power adapter, but I don't use the 'book anymore. Surprisingly, the battery level gauge in the menu bar is all red and the Control Strip shows a fully charged battery.
In the menu bar, at least with the OS 8.6 I am running, the red vertical bar or cylinder is a capacity gauge; when all red, the battery is full; as power is consumed, the red starts dropping down and the top is filling with blue. Your gauge indicates a fully charged battery.
The only time you see the lightning bolt is when the battery is charging and you will see it in the menu bar and the Control Strip.
You know the power adapter is connected by the presence of the plug in the Control Strip.
The bars in the Control Strip are all gray when the battery is fully charged and all white when empty.
Remove all power and take a look in the battery bay with a flashlight; gently touch each pin with the eraser-end of a pencil and see if any of the pins is loose or possibly set back beyond the others.
According to Apple service guides, if you have performed the resets and have a known-good battery and power adapter, the only fix is a logic board.
Do you have a 45w power adapter and have you tried another power adapter? You can use the PB1400 or 3400 or any G3 or clamshell iBook adapters.

MACBOOK WON'T RUN OFF BATTERY

My MacBook will not run off the battery.
I replaced the battery. Now when the machine boots the battery icon indicates that it is calculating for a few minutes and then displays an X in the icon.
I click on the icon at get the message that NO BATTERIES AVAILABLE.
The battery is charged and I have reset the SMC.
From all of the disussion groups this appears to be a common problem.
IS THERE A SOLUTION?

MacBook Pro won't power up. No charger light

I have a late 2011 MacBook Pro 15" with 2.4Ghz i7 w/ OSX 10.8.4
I did an Apple software update today. It included updates to iTunes and i think a Thunderbolt update also. It requested a system restart so I went ahead and restarted it and left the room. When I came back in about 10 minutes later it was powered off. I tried to start it back up but it won't do anything. The light on the charger wasn't on either. I tried another socket and another charger and same thing. Before the update I had a full charge on the battery and the charger was lit up so I'm pretty sure its not an issue with the charger or battery. Tonight I looked at it again and noticed that the charger light is on its just very dim where you can berely see it.
Has anyone seen this issue before? I have seen a few other posts similar but none where everything just died all at once. My warranty is out so I'm trying to find a way to repair it myself if possible. I use this laptop to do alot of video editing so it gets pretty hot at times. Hopefully its not damaged beyond repair. I have alot of PC repair experience but I've never messed with a Mac other than upgrading RAM.
Thanks in advance for any responses.

Thanks for your quick response.
I probably should have mentioned this before but I just got it back from repair about a month ago. I had a problem with one of the USB ports not working sometimes. They replaced the logic board and both RAM sticks. I will try the SMC reset when I get home in the morning. I bought it refurbished from Apple and the warranty just ran out about 2 weeks ago so hopefully the SMC reset will do something.
I did try removing the battery connector today for about 10 minutes but that didn't have any affect.
Thanks again for your help.

MacBook Pro won't power up and no charger light after USB device was plugged in

Hey guys,
I have a late 2012 MacBook Pro 13" with a water damage that didn't cause any troubles (until now).
A couple of days ago I plugged in a Samsung tablet to recharge it's battery on my MacBook. At the same time my screen went black and the MacBook powered off. No usual forced low-battery-shutdown or anything, it just died. From then on the charger light didn't work and I wasn't able to start the Computer anymore. From time to time the charger light was flickering a little bit but way darker than the usual luminosity. The Laptop had a water damage about a year ago, which didn't cause any trouble. I dried and aired it for a couple of days and didn't switch it on during that time. It worked normal for the rest of the year but now I think the mainboard is ******. Please tell me something different, or the truth even though it might be shattering.
Just in case it might be important. I was backpacking in Sri Lanka when the incident took place. It didn't seem like there was an overvoltage or anything like that though...
Thank you guys and have a good day.
Alex

Liquid damage is progressive.
Best action that can be done is to take the computer to the Apple store to have it checked out
and repaired if possible and affordable.
Best.
