I did not work for me in the beginning because Z500 didn't know it had a battery.

1. First do a clean install of Windows 7.
2. Install all the drivers only for Lenovo site and respect the restarts. Install Lenovo Energy Management last. Go to Lenovo Energy Management and set it for full Performance.
3. The indicator in the animation should be far right not center.
4. Go to Advanced Power Settings in Control Panel -> Lenovo Energy Management and hit ENABLE
5. Now you restart and you should be able to do the firmware update

6. If you cannot do the firmware update then uninstall LEM, remove ACPI from Device Manager, Reinstall LEM, Enable again.
7. If you cannot do the firmware update then try battery gauge reset in Safe Mode and remove ACPI after, and then Reinstall LEM, Enable.

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 problem with my Lenovo is somewhat the same but

If your computer works directly to electricity without the battery, then the battery is faulty. Battery showing you 99% does not mean it is working, because bad battries gets full on time. The cell of the battery might have been dead because only GOD knows how long it had stayed in the factory.

But if you are convinced that the battery is good, then check the adaptor, and if the adapter is good.

Just try to check everything to ascertain the fault. And let me know what happens next.

I wish you the best.

SOURCE: Hi, I am using ideapad

with laptop batteries its recommended that you charge it fully the first time and let it drain completely then charge it fully again and unplug it. you will do damage to your battery if its fully charged while its still plugged in and with all rechargeable batteries they decrease how long they can be used over time.

please let me know if this helped

SOURCE: Lenovo Ideapad Z570: Battery indicator shows the Power is plugged in & charging. But the Battery charge percentage doesn't increase. How to fix this?

The battery might be nearing the end of it's useful life and needs to be replaced. The battery only lasts for so long then it has to be replaced.

Buy a battery on ebay base on your computer's Make and model, not the model of the battery.

Sounds like debris in your cooling fan. Try vacuuming the open grills and see if the click goes away. This is usually caused by something sucked into the fan and clicking, like clothespinning playing cards to your bicycle spokes to make a motor sound as a kid. Since the fan is the only moving part in a laptop this is with 99% certainty the problem and the only way to fix it is to remove the offending debris.

Lenovo Z500 signal problem


Start by unplugging the router for about 5 seconds, plug the power back in. See how the signal is then, if not improved, you can try to log into the router and change the channel. Try 1, 6, and 11. Also ensure there are no other wireless devices that may be causing any type of interference (telephones, baby monitors, etc.) If any of these devices are close by try removing the battery to test if they might be interfering. Try updating the the wifi adapters to the latest version if you have not already done so. I am available for remote assistance on https://www.crossloop.com/RickPoitras if required. Thank you and have a wonderful day.

My lenovo z500 has a screen brightness issue. It very dim and it won't turn up no matter what I do?


Hi, I had this problem also and I don't know why, but Lenovo Ideapad Z500 seems to have some compatibilities issues with a new Intel video card.
So, what you need to do is rolling back the HD intel video card driver to the previous version OR go to the following path: D:\drivers\VGA\Intel\x64\9.17.10 and press Setup to install the old driver again.
That solved my problem. It's a shame that I can't upload this driver in my laptop.
