Replace the battery, it's faulty.

Batteries only have a useful life, then they have to be replaced. Sounds like yours is doing like the ink cartridges, where they register as being full of ink when actually there is no ink in the cartridge.

SOURCE: My battery in my Y510 Ideapad shows full charge

Check your power settings in windows set it for max run also Sounds like your battery shows the volts but no capacity 18 mo old this is very close to a replacement sugest aftermarket ebay battery Usualy when you do not run down lithium batteries they become unstable this means some of the cells in the battery hold less of a charge than others in the pack so this is the weakest link senario so you get the volts but when you put a draw volt brop right off and the computer shuts down. some times they can be reconditioned so all the cells hold the same cap but there is no warranty and cost about half of what a replacement battery cost. shop around.

SOURCE: My Lenovo T60 will not boot up

One Long and Three Short Beeps = Video (EGA) Display Circuitry has malfunctioned, meaning the video card has possibly shot!
try this: remove the battery, remove the hard drive, remove anything else connected to the computer, and now for the most important, remove the memory and clean the contacts (memory is crucial to the machine working properly), if you have two clean them both.
After this replace the memory (only 1 if you have 2) plug in AC power only and try to reboot the pc into bios, if you hear no noises, start to put everything back 1 by 1 rebooting the machine every time, if it start to beep you've found the faulty hardware, leave that out, job done :)

keep me informed please


regards

OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time.

Not really, the older NiCad batteries get a memory effect if you keep charging from a half charged state, but modern Lithium batteries do not suffer from this problem.

My lenovo G550 appears not to charge when the charger is plugged in despite turning the mains power on and off to see if power is getting though and the blue neon light showing on the mains...


Hi m529,

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.

I hope that this Helps.

Have a nice day,

mvincentc

Lenovo G550 battery shows fully charged but when you unplug the laptop, the laptop shuts down and will not start up again until power cord is plugged back in.


Shows a clear indication of the battery to be faulty. So in the first place remove the battery and checck the voltage, now keeping the battery off the laptop, plug the adaptor to the mains, Now checck the voltage in the battery terminals which is in the battery compartment. If voltage is present then the battery is bad as it is not charging.
However if there is no voltage then the main board has a fault in the charging section which must be looked into.

Dell inspiron 6400 Battery problem


what i would suggest is to check the bios there may be a new flash download on the dell website, my wife has a inspiron 1525, which is plugged in and says not charging, the battery will not go above 0%, but we have had to send it to dell (still under warranty) faulty motherboard. if the bios is up to date, there could be a hardware issue with the battery or motherboard
