After installing Windows 7 on HP laptop, getting message "plugged in not charging"

For all laptops these days there is three conductor cable that goes from the power supply to the laptop. The outer ring you see is the negative part of the terminal, inside the connector there is an inner positive ring. The very center is a pin which is "sense". Almost always the thin wire going to the sense terminal has broken. If you crack open the case for the power supply (you don't need to) and take an ohm meter you will see an open circuit from the center pin to the thin wire inside the power supply. You can cut the rubbery strain relief on the computer side with and exacto lengthwise, be careful and you can reuse it with some electrical tape. Desolder the three wires from the terminal, cut about 6" from the remaining wire, strip the wire, resolder to terminal and you're done. All of the **** like: unplug, wait, change bios, dance on one foot, etc. only "work" temporarily because you're flexed the intermittent bad connection.

Hi Sir

I have this problem with my adaptor, I have checked this three cable with ohm meter and all of this three cable was OK.

But I still have this problem, I think error is maybe in board of adaptor.

Do you have any suggestion about that?

thank you

Awesome. Works perfectly fine.

I had the same problem with my Compaq after upgrading to a 12-cell after market white box battery. What I did first was I uninstalled and reinstalled "Microsoft ACPI- Compliant Control Method Battery" and that did not work, so I followed the steps below:

1. close laptop and remove battery (while still on). 
2. open lid and remove AC adapter (while still on, will power off system)
3. close lid and connect battery
4.  open lid, connect AC adapter, and power on.

After I did the above, my system began to charge the battery. Some people say that after step 2, shutdown the system before unplugging the AC. I didn't because most of the solutions I found said NOT to shutdown the system first. If you were careful with your system, this one time shouldn't do any harm to your laptop

Listen Guys, I know this sounds ridiculous, but it worked. I don't know why, because i tried everything before this, i was seconds away from buying a new battery (thought mine got fried due to a broken charger) but this works

I find your reply to be quite interesting, and I am tempted to try it on one of the THREE laptops that I have that are experiencing this issue..  The only thing that is holding me back from disassembling, cutting, soldering, and taping, is the fact that this issue does NOT occur under Windows XP which originally came installed on all three of my older laptops (the ones experiencing this).  All three of my laptops have this "Plugged In, Not Charging" issue under Windows 7 Pro, but in an effort to troubleshoot the issue I tossed in a spare hard drive, installed Windows XP Pro on one of them and witnessed that this issue does not occur when running Windows XP.  It charges just fine under Windows XP, but not windows 7.

By the way, uninstalling the driver and/or disconnecting the battery/AC Power closing the lid, OR ANY COMBINATION of the driver and battery removal techniques has NOT solved this issue under Windows 7.  If i simply unplug and re-plug the AC power plug into the laptop (just a simple pull out, and plug right back in) the battery will charge for anywhere between 10 seconds to 10 min...  After that it reverts back to the "Plugged in, Not Charging" state.

As far as the poster that mentioned that Lithium Ion batteries do not like to be charged all the way to 100%, and windows senses that it is always plugged in so it doesn't charge the battery until it senses battery use......... Well my battery is down to 43% and it still will not charge.

The two things that i find interesting are:

1. The only Microsoft solution pointed to is uninstalling a driver and re-installing it...
2. This issue does not seem to happen under windows XP

This leads me to believe that this issue is with Windows 7/ a Windows 7 driver and needs to be fixed.

I should mention that all three laptops are older and were designed for Windows XP, Running Windows 7 on them (even though they are very decent laptops) was/is not recommended or intended.  But with that said, ALL of the other hardware on all three of my laptops experiencing this is fully supported and works great under Windows 7...  Everything but the dang battery charging.

My three systems are:

HP 550

Intel Core 2 Duo 180Ghz with 4GB Ram running Windows 7 Pro 64 bit

(Own one genuine HP batery, and have the Plugged in, Not Charging)

Dell XPS M140

Intel Pentium M 1.73Ghz with 2GB Ram Running Windows 7 Pro

(Own two aftermarket batteries, both have the same Plugged in, Not Charging issue)

Gateway NX260X

Intel Core Duo with 4GB Ram running Windows 7 Pro

(Own two genuine Gateway batteries, both have the same Plugged in, Not Charging)

So after this lengthy response, I implore someone to please solve this issue.
