Lenovo Z400 P/Y/Z Series :: When Battery Charges Until 60% / Does It Internally Disconnect Charger From Battery
Jan 30, 2014
I would like to ask about the Lenovo Energy Management software bundled with my Z400. Regarding the Energy Management > Battery > "Optimized Battery Health" in particular. When the battery charges until 60%, does it internally disconnect the charger from my battery? The Power icon in the System Tray says "Plugged in, not charging". Or does the software stops the charging until 60%, and when it lowers the software allows it to recharge again? I'm worried about getting my battery worn out immediately, as I leave my charger plugged in most of the time.

I bought my lenovo z400 ideapad beginning of April this year and just about two days ago it just turned off and though I plugged it in later it started saying 'plugged in but not charging'. What do you think is the problem?
Furthermore I lost the receipt ( the sales receipt) but there is still the model/series no. , is the warranty still on?

I've looked at the other threads and tried removing the battery while the laptop is off for 30-40 seconds but it doesn't run because it's not getting power from the charger at all.
The laptop is a couple years old and the hinges on both sides have been pried off (can provide pics) but I never had problems until now - I plug the charger in but it won't charge and even if I pop the battery out it STILL doesn't charge!
One night, I had to set the charger upright in order for it to charge. Today I had to set the bulky and heavy part of the charger higher above the laptop in order for it to charge. Now, how to get this thing to work because proping the charger upright or higher than the laptop isn't working anymore!
I've noticed a couple weeks ago when I was visiting my parents that the adapter emits a beeping sound - notice that I said the adapter NOT the laptop. If I unplug it the beeping sound fades. The beeping sound comes from the adapter and when I unplug the cord going from my laptop to the adapter you can hear the beeping sound fade away from the prongs that conect the adapter to the laptop (not the prongs that plug into the outlet).
Like I said before it doesn't matter if I've plugged it into an outlet with OR without the battery in it, the laptop does not receive any power from the adapter or recharges.

The battery is clearly a refurb. I believe refurbished batteries are just fine, so long as they are built by reputable & knowledgeable folks who are using newly made replacement cells.
But this battery will only charge to 47%. The 5-light strip on the back lights two lights only (no blinking). A handful of programs all say the battery us at 47%.
I think this may be an issue with the smart board inside the battery. Is this something that gets calibrated through the bios? How do you run "battery learning"? (...or is it shot?) ..

MY Compaq notebook's battery will only charge if I remove it and reinsert it. Is the battery defective or something on PC?

After 6 months of moderate use, the battery on my 3810T seems to not want to fully charge. The battery indicator in windows (win 7 home premium 64bit), shows the max charge at 88% and the front led stays yellow for a long time when plugged in (over 12 hrs) before finally just turning off instead of going to blue to indicate a full charge.

My 2 day old Lenovo Y510P laptop has a problem with charging. I noticed the battery was never going above 60% charged. I left it plugged in for over 24 hours and nothing changed. So I decided to completely drain the battery and used the laptop until it died. With the laptop off I left it plugged in until the battery LED turned white which indicates the battery is fully charged. Unfortunately the battery still shows 60% charged.

About 2 weeks ago, my z400 automatically updated from windows 8 to windows 8.1. i have been read reviews on whether or not to restore my computer to its original state or continue with 8.1.i have noticed several malfunctions in my unit after the upgrade and quite frankly i am really hesitant on continuing with 8.1.

how the Intel HD Graphics 4000 is covering all my needs perfectly for the moment, I would prefer to disable the NVIDIA dedicated GPU in my Lenovo Z400 for a while.I've already went to the control panel and set the Global Settings for integrated but it still turns on (for a very small amount of time) every now and then.
From my research I would guess I would do it by: (Windows 8)Disabling the "NVIDIA GeForce GT 635M" driver in the Device ManagerSwitching from "Switchable Graphics" to "UMA Graphics" in the UEFI settingsI would like to know/confirm if:"UMA Graphics" means the Intel HD Graphics 4000 in my caseThe NVIDIA GPU will not actually turn on and generate heat/consume energy.
Laptop: ideapad Z400
OS: Windows 8.1 (64 bit)
CPU: Intel i7-3520m (w/ Intel HD 4000)
GPU: NVIDIA GeForce 635m
RAM: 8GB @ 800 Mhz

I don't want to use the BIOS update method because I think it will make my computer not working anymore.
How do I press [F1], [F2], [F3], [F4], [F5], [F6], [F7], [F8], [F9], [F10], [F11] and [F12] without everytime pressing [Fn] to use these keys. So the original keys are: [Mute], [Vol-], [Vol+], [Close], [Refresh], [Touchpad], [Airplane] [Apps], [Screen], [Projector], [Bright-] and [Bright+], I want them to be: [F1], [F2], [F3], [F4], [F5], [F6], [F7], [F8], [F9], [F10], [F11] and [F12], and when you press [Fn] they be: [Mute], [Vol-], [Vol+], [Close], [Refresh], [Touchpad], [Airplane] [Apps], [Screen], [Projector], [Bright-] and [Bright+].

So since I've bought this computer I've had problems with the two-finger scrolling suddenly stopping, like many people have. That's always been fixable by going into properties, device settings, settings, unchecking/rechecking one of the boxes under "two finger scrolling" and hitting OK.
Now, though, my touchpad is suddenly stuck on one finger scrolling, and it's super annoying. There is no "one finger scrolling" option under the "scrolling" drop down thingy under device settings, so I haven't a clue why this is happening. I've tried the usual fix above, restarting the computer, installing new drivers, but it still does one finger scrolling. Which means it scrolls a lot of the time when I don't want it to, and the pointer seems to get "stuck" at times when I'm just trying to move it around.

My battery charger doesn't charge and the blue light isn't turning on.
Is it safe to assume that it is dead?
Are there any tests I can do to verify if that's the case?
I've had it for a year and 3 months, is that the typical life of a battery charger?

Hoping for some insight.
I have a 90w Dell charger that came with my studio XPS 13 (6 cell).
If I was to use this charger on a 3 cell Dell Inspiron Mini 12, can this seriously damage the 3-cell battery, or are the chargers smart enough to know what type of battery they're charging?

Do you have to send the defective one in? If so, I'm not going to bother with getting a replacement.

Basically my 1640 laptop has worked perfectly pretty much constantly plugged into the mains for two weeks but now I have to charge it while switched off and then take the charger out when I switch it on, because otherwise the laptop just powers off after a minute of loading up Windows 7...
Also if I try to plug in the charger randomly then it just powers off.!

For 2 weeks or more now, my network is giving me lagspikes/disconnect when playing online games like League of Legends every time there is a bit more action on the map(ping goes to 900+).
Have windows 8.1..I am using Wi-Fi, here's a screenshot of my drivers.I dont have this problem in another city, where I'm studying(I insert cable there for connection(campus network)).Also here at home, my brother has the exact same computer and w8.1 and he doesnt have any connection issues.
I dont have torrents, antivirus updates or any of that going on while playing.We have maybe 4 computers and probably 1-2 phones using the net aswell, but that doesn't seem to be the case, as I said these problems should have occurred with my brother's computer aswell? Also when these devices are not in the house, I still suffer from lagspikes.

My inspiron was working fine until yesterday.Today,when I tried to use it,
1.My laptop does not power on (no matter how many ever times I press the power button.)
2.My battery charger's led glows brightly when connected to the power outlet but not the laptop(when power supply is switched on).But once I connect it to the laptop,(and switch the power supply on)the led blinks once and goes off.
3.I disconnected the battery,tried the same thing (without the battery)but the result is the same.
4.I contacted a local service center through phone and they said that it was a reverse current issue.

I have had my Lenovo U430 touch for about a month now, and have noticed a problem with it. Sometimes when I leave my Lenovo u430 touch alone (with full battery), and sometimes it will just power off without me doing anything. It even happens occasionally when I dont use it for a few minutes while im working in front of it.
It is definitely a power-off problem for me, rather than hibernate/sleep as my programs are no longer running when I turn it back on.
Hasnt caused any lasting damage as yet but am worried it could happen while im working on something important.

I was wondering if the default Energy Management battery setting of 50% can be changed on the Lenovo V570. I keep the laptop plugged in almost all of the time, and the popup suggests using the setting that keeps the battery at 50% all the time. That's fine in terms of not over stressing the battery, but if I need to unplug the laptop, I'd rather have a fuller charge than only 50%. I'd read that ThinkPads can be set to 90% or other settings. Is that possible with the V570?

I bought a Lenovo G505s laptop 4-5 days ago, but I have a problem. When I start Windows, it says 'battery not detected'. I found a topic about this, and I can fix it, if do the 'battery out, AC adapter in, deleteing Microsoft ACPI-Compliant Control Method Battery from device manager, shutdown, AC adapter out, battery in, AC adapter in' method The real problem is, that I have to do this every single day I wake up. Maybe it's because I don't updated BIOS, or it's a software/hardware error?

I received my y510p yesterday and the battery was at 32%. After charging it overnight, it's now at 34%.
I've been reading some threads on the matter, for example: [URL]... and whether my situation was similar, or different in the fact that
A) the other posts indicated a working battery for at least a couple of months, and
B) their systems are a bit older and it's possible Lenovo fixed the issue?
I understand there's a power management center in all Lenovo laptops and I can look at that...but even if the settings are to maximize battery life wouldn't this still allow for a charge above 33%?

I bought this Z710 new but I get a message saying "The battery is unauthorized". Also the battery indicator stays at "0% available (plugged in, not charging)." If I unplug the power cord, the laptop powers off cold. It has always been this way. This is a problem for me because I want to upgrade my BIOS but I can't because I get an error stating "Battry is too low (0 < 30 ). Please charge your battery to 30%." when I try.
How do I get this laptop to start interacting with its battery? I have already tried taking it out and putting it in again and rebooting.

I recently got the Z500, working under Windows 8.I got a question regarding the battery charge. I work on the laptop for extended periods of time with the power plugged in. Since this is bad for the battery, is there any way to disable the charging or to perhaps remove the battery?I wasn't able to find anything similar for this model.
