Hallow Dear, As your explanation about Battery issue simply I’m advising you to replace your battery with original one. But before that there is one thing that you can try it out. ---Use your laptop until battery goes down & shutdown automatically then remove the battery and try to discharge it completely with small bulb manually When it’s on completely discharge (0 Volt) keep it on Outdoor Sunlight about 12 hours. After that connect it to your laptop & recharge it completely (until Computer LEDs showing you as Fully Charged) ****** REMEMBER DO NOT TURN ON YOUR LAPTOP****** Until its Showing you as fully charged That will be nice if you can check Battery Voltage & Amperage manually as it is charged fully before turn on your laptop. (if not you can give more charging time accordingly) This will not solve your any component (thermal fuse, vRegulate) problems inside your battery but will increase your battery Cells Life and most vStoraging problems on Cells inside your battery Thank you & Best Regards Dinu….

From what I've experienced, repeated restarting, and frequent shut downs, can be traced back to a defective power cord, and/or a low battery state. Garmins operate best with a full battery charge, regardless their connection to external power.
If you can get it to connect to your computer, and can see it as a device with removable storage, right clicking on it's icon, and select "properties" to show you the battery-charge state detected.
Mine won't charge when connected to the computer for some reason, and won't boot even if left for a few hours, but if I connect it to a dedicated usb charger, (the kind that plugs into an A/C outlet with a USB port) it will begin to charge. After fully charging it returns to normal operational state. If it still can't charge it may need a new battery...
Does the laptop work on AC ? Is the battery or cord/charged a replacement? First, try another cord/charger of the EXACT same specs as original. Second, Is the battery good? How old? Over 4 years? Have it tested. Beware of inexpensive aftermarket batteries and cord/chargers. I assume the laptop works on AC? If you unplug the AC , with battery in, the laptop shuts down immediately?
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.
The first time you charge the battery allow 12 to 16 hours, after that 2 to 4 hours or when battery is charged. If you go on battery frequently drain it right down before charging it, this will give the maxi-um performance and longevity.
Hi there, to use or running Notebook in a battery, simply unplug the battery charger ( power chord) and your battery should be fully charged.
by the way, if ou having the problem of a laptop shutting off when you unplug the
charger when your battery is fully charged, there is nothing wrong with the laptop, battery, or computer, it is a
power management setting. What you need to do is:
Go to display properties
select the screen saver ta and click the "power" button
In the power schemes tab there iss a drop down window, click it and select "Portable/Laptop" (it is a power switching utility that quickly switches between AC and
Battery when the power cable/charger is plugged in or unplugged while
the laptop is on)
hope this help a little, ask me if you need more assisst. regards
Are you sure it was fully charged before? Could you see the full battery bars?
It sounds like your AC adapter (the charger) has likely gone bad. The phone battery probably wore down, and when you plugged it into the charger, the charger couldn't charge it, so the battery remained dead.
Since the battery is not charged, you can't turn the phone on at all when it's not connected to the charger. And when you do connect it to the charger and turn it on, you get the intermittent charging because something inside the adapter has a faulty connection -- sometimes it works, sometimes it doesn't.
You can easily verify if the charger is the problem by getting a new charger (they're not too expensive) and seeing if the phone will work and/or charge with the new charger.
If the new charger doesn't fix the problem, post again here and we'll go from there, but I think the new charger will take care of it.
When the ac adapter is plugged in does the charge light come on to indicate the battery is charging? If not, the charger has probably failed. Faulty battteries can also cause a charger to fail. Both need to be checked.
IT sounds like your laptop or powersupply/charger is at fault. Try to use a different charger, and if possible use your battery in a different computer. That way you can narrow down where the problem is.
It might ba a faulty connection where the charger is connected to your computer. To check this out, try running the computer on AC without the battery installed. If it suddenly shuts off it's a problem with your powersupply or possibly the connection plug in the cimputer.
