Please 1. unplug the ac adapter, detach the main battery, press the power button for 15 seconds, plug in the ac adapter, and restart your laptop. If the problem persist: 2.unplug the ac adapter, detach the main battery, press the power button for 15 seconds, take out the hard drive, plug in the ac adapter, and restart your laptop. If the problem persist, then it means that the laptop motherboard is dying. Please read your laptop's service manual before you open the laptop's case/body.
it could be that the connection jack on the mainboard has been dislodged from the solder joint, common among Gateway comuters and HP units too. is the DC jack loose from the notebook ? if so thats the issue it seems. You will have to bring it to a computer person to resolder. if not and youc an do it yourslef, save money -- but be careful not to damage anything on the mainboard.
I see you are having issues with you G550 charging.
You mentioned that the light on the charger is lit up but then it suddenly switches Off, and you also mentioned that the charge still has a light but the power is somewhat low despite of a fully lit up charger Light.
Have you tried draining the power from the system?
Remove the battery and the Charger or AC Adapter as well call it from the G550 then press and hold down the power button for 10-15 seconds to drain power from the system motherboard.
Once drained connect the AC adapter but do not connect the battery yet, then turn the Laptop ON to see if the system will power ON using the AC adapter/Charger if it powers up then there is no problem with the AC adapter/charger.
After testing the AC adapter if it is working power down the Laptop doing a normal shut down.
Once shut down or turned Off insert the Battery back in the Laptop then turn the Laptop ON using the battery only without the AC adapter/charger see if the system will turn ON using the Battery only.
If the Laptop powers On using the battery alone with out the AC adapter then the battery is most likely working as well on the issue.
Now power down the Laptop then connect the AC adapter to the Laptop with the Battery in the Laptop as well then turn the system ON again see if the problem will Occur again having the battery and the AC adapter/charger if the Problem happens with both Battery and AC adapter on the Laptop then the problem is the Motherboard, most probably the motherboard is having issues relaying power from the AC adapter to the battery and may be sent to the Depot for repairs.
I suggest that you call Lenovo for further information about your system, if you still have warranty and is still in the one year period then your system will be covered for any repairs needed - you can call @ 1 877 453 6686 for troubleshooting, you will be asked for a serial number Located underneath the Laptop on a small white sticker that states s/n meaning serial number.
If your computer won't charge the battery, but the battery charges fine in another computer, and you are sure that the charger is good, then your problem is probably the DC power jack. If you wiggle the end of the power cord where it attaches to you laptop, and it starts charging properly, then the DC power jack is broken.
Take the battery out and discharge the capacitors by holding down the power button for 15 seconds. plug in the charger without the battery in to see if you get a charge light. If you do, replace battery and plug in charger and power on laptop. If this does not work, you may have to pull the cmos battery for 15 minutes and try it again.
Change your AC charger. It's NOT charging "When the laptop is plugged into the AC, the power meter in windows
tells me that the power source is still batteries, and the battery
level drops by about 1% every few hours" That's the reason why: "battery has completely died" If you do not change it you'll continue to "still it gives me the same low battery indication and will not turn on.
This issue can be caused by any of the below possibilities.
1.- Computer AC / DC cable is bad not allowing the computer battery to charge. 2.- Battery is bad. 3.- Battery charger board is bad.
Solutions: 1.- Computer AC / DC cable is bad not allowing the computer battery to charge
Verify that the AC and or DC cable is not bad by testing the computer only with the power plug connected and the battery out of the laptop. 2.- Battery is bad
It is possible that if the power plug is good that the computer battery is bad. Leave the computer connected to the power with the battery connected in the computer for at least one hour; if the battery does not charge, consider having the battery and/or the laptop serviced or repaired.
If the computer and/or battery is not in warranty consider just replacing the battery as it is very likely that it is just a bad battery. 3.- Battery charger board is bad
If the battery has been replaced or an alternate battery from an alternate identical laptop does not work in the computer, it is likely that the power or charger board within the laptop is bad. It is recommended that the laptop be serviced or repaired.
This will fix your problem.

Try to turn off the computer and remove the battery from the bottom of the notebook. Turn on the computer with just the charger plugged in. If it doesnt turn on. you may have a bad power port.
If it has no power/charging issue since that happened except that the indicator light doesnt turn on when you plug in the charger, you may just need a bios update. Click here. That's the bios update for the inspiron 2200 from dell's website. You should have at least 30% charge on the battery and the ac adapter should be plugged in so you can run it. The computer will restart and will come back normally after this. I'd suggest that you backup your files before running this.
it means your battery is too discharged to charge. when you plug the phone in, it doesn't use the AC power right away, it uses the battery to jump start it until the red lights come on the front, then it will switch to the AC power. try this. turn on the phone with out it plugged in and as soon as those front lights come on, plug the charger in. if the battery is not too discharged i.e. it didn't power down while you were talking to it, it should work. I went through three batteries until i figured it out
