Hi Friend My Laptop Lenovo G580,last week m y battery is not charge and Power light and Battery light frequently blinking.Can plz suggest.I am so Afraid about this issue.battery is still good

Measure the voltage at the AC Adapter plug, and see if it is within 5-10% of the rated voltage. If the voltage is not correct, then the battery will most likely not be charging, and the system will drain the battery and die in the middle of what it was doing...booting in your case.

You can tell how much voltage is remaining in your battery and if it is charging by checking the blinking of the battery status light.
Download the Hardware Maintenance Manual here:
http://download.lenovo.com/UserFiles/UserGuide/en/User%27s%20guides%20and%20manuals/Z370&Z470&Z570/Lenovo%20Z370Z470Z570%20Hardware%20Maintenance%20Manual%20V1.0.pdf
and go to page 30 and look at item 7 under battery status for blinking light meaning.
1. Blinking amber: (500ms off/1s on)
The remaining power of the battery is less than 5% of
its capacity.
2. Blinking amber: (100ms off/3.2s on)
The battery is being charged with the remaining
power between 5% and 20% of its capacity.
3. Amber: The computer is operating on battery power with the
remaining power between 5% and 20% of its
capacity

With the AC Adapter plugged in, and giving the correct voltage, If you are getting 1. Blinking Amber (light on for 1 sec, off for 1/2 second), then the battery is not being charged. Could be AC Adapter, Battery or Battery Circuit on motherboard. If the light is solid on 3. Amber, then the battery is not charging, and is draining.

Also make sure the power socket on the laptop is not loose or damaged. If it is, then it will need to be replaced.

I hope this gets you in the right direction.

is the charging lid light when it connect to charger if not use another charger firstly if the problem still there may be in laptop motherboard.erase the battery before use the new charger

Return it. Get a UPS for the next computer.

hi, check for low battery try to full charge first. then check the power adapter if their is an output going to the laptop.

Hi,

This is going to be one of three things either your power supply is not giving out enough voltage to charge the battery, have you tried another psu?
If its not the psu then it could be the dc socket being loose on the mainboard or the fuse which controls the charging section has blown which means you need a replacement mainboard. Usually its either the charger or dc socket

Exactly what happened to my v570.. power supply is stable when unplugged to the laptop but blinks when plugged in..i took out the battery .. same thing.. any other solutions here?

Hi there !

Yes, you can self diagnose your laptop if your laptop is not charging and most common problem is the charge adaptor is broken which means power light is not on when you connect your power cable to power supply. For laptop, battery problem, usually the power light is blinking orange light, giving you a warning on hardware failed which is the battery is damaged. But if your laptop is new, I believe the charger is the problem or not compatible with the laptop unit.

I suggest also to borrow from a friend, if you can, a charge adapter to check if charging and if so, that is the problem.

Good Luck and I hope it helps you. Thank you for using FixYa !

hi! just a tip probably there is a problem on the power board, just a suggestion if your still on warranty might as well call lenovo tech support so that they could replace the defective part. hopr this helps! goodluck!

Try to perfrom power drain. You must first turn off the computer. Take out the battery and unplug the power adapter. Press and hold the power button for 30 secs. Put the batter back in, plug in the power adapter and power ip the computer then observe.

Let me know if same issue will happen.

Hi,
I,d suggest To charge the battery Fully.
Then power up the laptop, with A/C Adaptor connected.
Also check your models user manual, regarding the sleep/hibernate mode. the laptop may have gone into one of these modes. Usually a ( zzz ) Icon Key or Similar.
Also when booting press the LCD/VGA Button.
If all else fails, try to see if your laptop, has a hard-reset button or switch. ** Sometimes this can be a small hole ** On the underside of laptop. *** Only use with laptop Powered Off ***
