My Pavillion dv7-3048CA won't charge

I bought my dv7 back in December 2009 and it has been running smoothly up until now. Whenever I connect the adapter to the laptop (battery put in) it will charge, but once I unplug the adapter and leave the laptop running on battery power, it no longer charges the battery when I plug the adapter back into the laptop.
This happens every time and whenever my laptop is close to draining out, I always have to do a power-drain where I unplug everything from the laptop (USBs, battery, adapter) and shut down the computer. I then hold down the power button for several seconds to drain the power before starting it back up with the adapter (no battery). I always have to do this whenever I unplug my laptop from the adapter and let it run on its battery. It's getting really irritating and I don't know what to do.
Help, please!

Try another AC adpater if you can.

Pavillion dv5 1235dx won't charge.

I just installed windows 7 on the hard drive after a full wipe, now that the software is up and running the LED for the power adapter will no longer show that the battery is charging and even if the laptop is off it still refuses to charge. I was going to run the BIOS flash to see if that would solve the problem but it says to do it with external power connected and I'm afraid to do it under battery power.
This is NOT the first time it has happened, the first time it stopped I had it checked under warranty and HP replaced the hard drive for what seemed like no reason at all.
Also, there have been intermittent cases where the laptop has refused to charge and unplugging it from it's current outlet and into a different one has solved the problem, but this time it doesn't seem to be doing the trick.
Any ideas.

Hi,
First of all, shutdown the notebook, unplug the AC Adapter unplugged, remove the battery, and then hold down the Power button for a full minute.
Now, plug in the AC Adapter and see if the notebook will start without the battery inserted, if it does, open windows Control Panel, open Device Manager, expand the entry for Batteries, right click on and theMicrosoft ACPI Compliant Control Method Battery and selectUninstall - do not uninstall anything else here. When the uninstall is complete, shut the PC down, unplug the AC Adapter, re-insert the battery and then start the notebook on just the battery. Windows will automatically reinstall the driver - leave Windows running for a few minutes without doing anything. Then shutdown the notebook again. Plug the AC Adapter back in and Start the notebook to see if this has helped the issue.
Best wishes,

DV7-3165 battery won't charge

Hi my HP Laptop Windows XP DV7-3165 model won't charge when I plug in my power chord. It hovers at 18% charged and has the message (plugged in, not charging). This never happened before and I tried looking at the power options menu in the control panel but nothing can get the computer to recognize the power chord anymore. Any thoughts?

Hi,
It may be worth trying the following.
First of all, shutdown the notebook, unplug the AC Adapter, remove the battery, and then hold down the Power button for a full minute.
Now, plug in the AC Adapter without the battery inserted, start the notebook, open windows Control Panel, open Device Manager, expand the entry for Batteries, right click on and the Microsoft ACPI Compliant Control Method Battery and select Uninstall - do not uninstall anything else here. When the uninstall is complete, shut the notebook down, unplug the AC Adapter, insert the battery, plug in the AC Adapter and then start the notebook. Windows will automatically reinstall the driver - see if this has helped the issue at all.

Hp pavillion dv7-3065 laptop will not turn on - led light blinks, ac's light on?

HP Pavillion dv7-3065 with Windows 7.
I fell asleep two days ago, and when I woke up yesterday, my laptop was off. (The battery very well may have died while I was sleeping, or just shut off on its own. I don't know which.) I tried turning it on, but nothing happened... except for the lightning bolt (LED light) blinking three times. No noises inside, blank screen, nothing aside those three blinks.
For the record, I've already tried removing the battery. I've also tried removing the battery, removing the AC cord, and holding in the power button for 30+ seconds. It didn't work.
I've tried removing the battery and running off AC. This still doesn't work. However, the laptop recognizes that it's plugged in; the little light by it is consistantly on. I've also tested my laptop with another AC adapter just to be safe. Nothing.
My laptop has been tested without harddrive/etc, but I'm still at a blank. I don't know what else to do. My boyfriend, who's in school to be an IT, took it into his teacher, who messed around with it, and came up with a few conclusions.
He believes that because the lights are flashing, he's confidant that my motherboard is fine. He said to replace the battery, and if that doesn't work, solder the ...I forgot what exactly, but basically it's the charging connection. I forget what exactly. My apologies there.
However... I feel like replacing the battery would be a waste of money... Because regardless of battery, the laptop should still turn on with the AC cord. My boyfriend intends to bring this up and ask if he can just skip to the other thing anyway, but he doesn't have that class again for a week, and I'm at a loss of what else to do. Aside from that, his teacher says there's a limited number of other things that could be wrong...
I was hoping to get some more input...

This won't help you out, but I am experiencing the same problem... I am gonna look on this post to see if you get an answer!
I have the same problem! Except I did manage to get mine to turn on. After doing the hold the power down thing. Nothing happened. I did leave the lap top on cause I was irritated and walked away, about an hour later it came on. It let me turn it on and off a few times. Then stopped. Then leaving it sit on stopped working too

HP Pavillion DV7 Hard Drive failure and replacement

Hi all,
As the title mentions, I have an HP Pavillion DV7, p/n: NB406AV. The SMART is showing an imminent hard drive failure. The primary hard disk quick test stops at 4% and shows a code "303" for hard disk 1. It also stops at 4% when doing a full HD scan.
So, I'll be replacing the HD. I have no idea what to buy, and I plan on buying a non HP HD. Can anyone tell me the specs I should look for? I'd like to get the biggest GB HD that will be compatible as well. Thanks for your help!

Hi,
It usesSATA HDD. Some dv7 models use SATA II but many later models use SATA III. SATA III is backwrd compatible but more expensive. DV7 is a series of hundreds different models and you won't go wrong with SATA III drive. It can accept current generation HDD's. The following HHD is a good choice with a good price/performance ratio per Gb:

You can use 1Tb on your machine. New HDD's are thinner but the screws will be lined up and should be strong enough to hold the HDD in place.

Hp Pavillion Dv7 Recovery Disks

I really hope someone can help me out.
I have an old Hp Pavillion Dv7-1262 i bought in 2008. I had to restore it twice before and ordered the recovery disks from HP around 2010. The recovery disks come with Windows Vista Home Premium. They have worked perfectly before no matter the problem even when i bought a new hard drive.
Recently my laptop for some unknown reason stopped booting any software/operating system. Computer turns on but does not load Windows.
When i put the disks in Recovery Manager appears (does not give any other options other than loading the disk) but it stops almost half way through. The error message 1005 and does not let me put in the second disk out of the three.
Anyone know what it could be? Could it be the hard drive? or do the Recovery Disks need to be bought again? (there is no damage to them, have they run their expiration?)
If its the Hard Drive what kind should i get?
Thank you

IPhone 5 connected but won't charge

So i have a iPhone 5 that connects when I plug in the lighting cable but it won't charge sometimes. I already cleaned out the port on the phone with a dry toothbrush, please help. I've tried a lot of things and if there isn't a solution i'll just buy another battery.

My 4th gen iPod Touch won't charge

Hi, folks:
Suddenly, my 4th generation iPod Touch won't charge. I don't mean it won't hold a charge; I mean it WON'T charge. There's no (peep!) when I attach it to a Mac, a Windows box, or to the wall. I've tried not only at my place but at my doctor's office, too, on his computer. Rats.
It fell three feet onto a concrete floor a week before this happened, so I'm unsure of cause/effect there. However, chances are most excellent that I touched it while filled with static electicity (my bed is exceedingly staticky). Maybe I touched the charging port? I have no idea, but I kinda sorta have a memory of having gotten a shock while touching my pod and wondering whether that was bad.
It'll be a couple more days before I can get to a Genius Bar (but thank cow I'm in New York City and have my pick of them!). In the meantime, can anyone calm me down about my situation? Do you imagine it's doomed (it IS still operable provided I keep it plugged in, though iTunes can't see it since it won't mount), or do you spose the installation of a new battery might bring my precious baby back to me? It IS freshly backed up (again, thank cow!), but I'm not in a position to buy a new one right now, and unfortunately, I don't know what to do with my eyeballs without a Touch in front of them.
Oh, how I hope someone can tell me that this has happened to him, and an Apple Genius merely did something magical and handed it back intact and amazing again so Ican cry happy tears. It's been four days and I'm just sick without it (and having to look at this gigantic Mac, with its large and beautiful text in many windows, means I can't RECLINE! WAAAAH!).
Thanks for any soothing words you have, and if you have sad ones, well, I'll vag up and read them, as I've prepared for the worst anyway (sob!). Just please deliver them gently.
I appreciate it!

Wow, Kevin; that's a tantalizing theory! I don't like it (I *never* like to think about logic board damage for any piece of hardware), but it's tantalizing, as it would explain my pod seemingly charging out of thin air, and it'd also explain why my pod doesn't just DIE altogether from a dead battery.
I feel like an idiot: I have iTunes set to never sync automatically with my pod, so it never automatically recognizes the pod. I'll bet I could sync it if I clicked to "apply," as I've been downloading new apps since 2/21 (the last time I backed the pod up, mere minutes before it failed), but I don't want to risk not having a connection that's 100% and bollixing up what's on the pod now. (I'll be in the hospital for a day and will need something to read the whole time; I'll need an intact pod!)
Thanks for sticking with me, Kevin; I always like figgering things out, and your theory's interesting. I'll mention it to the Genius. It doesn't give me any hope, but not having any hope, I can always be pleasantly surprised, whereas if I go in all hopeful, someone can dash my dreams. This way, I'll prolly just have my expectations met.
I appreciate your talking it out with me a lot!

My iphone 5 won't charge :(

My iphone 5 won't charge with the cable I bought, I don't know if its because maybe it isn't an apple product? Can somone please help me! thank you

If you did buy a 3rd party product, that could be a reason. Can you check with an original Apple USB cable?

My Iphone 5 won't charge while turned on.

My iphone 5 won't charge at all while turned on. I have to turn off my phone in order to charge it. I can't really use my phone now because of the iPhone 5 battery life. I need help!

You are going to have t take that to the apple store . Make a Genius Bar appointment and they will help you. Most likely they will give you a new phone. Hope this helps

My iphone 5 won't charge anymore

my iphone 5 won't charge anymore

Hello Angelpz11,
I recommend this from our iPhone: Hardware Troubleshooting article found here http://support.apple.com/kb/ts2802:
Battery does not charge from the USB power adapter
Important: Only original iPhone can be charged from a FireWire-based power source. If iPhone is connected to a computer that's turned off or is in sleep or standby mode, the battery may drain.
Verify that the outlet being used is working.
Try another USB power adapter if available.
If no other USB power adapter is available, try connecting to a high-power USB 2.0 port (not a keyboard). The computer must be turned on and not in sleep or standby mode.
Try another USB cable if available.
Also refer to iPhone and iPod touch: Charging the battery.

Macbook won't turn on, won't charge either (no green/amber light)

So I was cleaning my keyboard today (just with water and a towel) and after cleaning, the screen shut off but my macbook was still turned on (could hear the fans). It wouldn't respond to anything and I tried a hard shut down but this did not work either. I was forced to take the battery out to shut it down.
Now it won't turn on. I tried plugging it into my magsafe power adapter but it won't charge. There is no light (neither green or amber). My battery still has 2 green dots when I test it.
I've tried resetting the power settings by removing the charger, battery, and then holding the power down for 5 seconds. This did not work.
Any help would be greatly appreciated.

I've had a very similar problem. My battery died about nine months ago and I've been going off AC since then. It recently started not turning on though.. I closed the lid one day and went for a walk and when I came back about an hour later it was like it was in a constant sleep mode. Since then it turned on once successfully. But I am getting the same dim green light for about three seconds and then it goes full. When I try to turn it on the fan or hard drive (not sure) starts spinning and the screen flashes but then it just sits with the sleep light on. When I read your thread though I realized I may have gotten it wet when carrying it to and from my car. I no longer have a warranty or care plan or whatever so apple won't help me one bit. SO yeah I thought I'd share that and maybe it can help you somehow..
