I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

I'll try and explain this one best i can. User came to me with their Yoga 15 with an issue where it randomly shuts down on battery power, as in completely switches off.  It sometimes displays a message to say the battery cannot be detected, other times just shuts down. The conclusion I've found is that when the bottom panel is off the machine the battery is completely detected in Windows, and the Lenovo Settings app. It runs fine, never cuts off even with lots of IE instances open.As soon as I put the bottom panel back on the battery appears to be disconnected in Windows, and it also shows it not charging. Intermittently it also states the battery power is low or not detected when booting up. Found that there's a battery / system reset button on the underside that may be the cause of the issue. Pressing this button with the underside of the Laptop off resets the machine entirely, I believe it's the battery reset button incase the machine ever gets stuck at any point (as by rights it's a non-removable battery and there's a small pin hole on the case over this button). Works flawlessly without the bottom case in place, as soon as I re-connect it when the unit is on Battery power I loose the battery status in the Lenovo Settings app. The machine will then randomly shut down. Any thoughts on this one, it's the strangest thing. Many thanks all.

A:Lenovo Yoga 15 - shuts down on battery

When you put the panel back, is it touching/blocking any wires?
Have you tried to do a factory reset? If everything works fine then, try updating drivers one by one to see if it comes back.

Hi, I have a new Lenovo Yoga 900S. Everything was working great until Windows automatically installed the anniversary update last night. Now, the battery won't charge. Thankfully, the laptop seems to be running on A/C, since the battery is not draining. But it won't charge. I've checked the energy management settings, and I've tried uninstalling the Microsoft ACPI-Compliant Control Method Battery driver. But nothing has fixed the issue. Please let me know if you've encountered this problem. Thanks.

Hello I recently bought a Yoga 900S and it was working fine for a day or two, but suddenly the battery symbol had an 'x' and it kept saying BATTERY NOT DETECTED. When that happened, my laptop would only stay awake for a few minutes or seconds then shut down. When I put it on charge, the 'x' was still displayed over the battery symbol but it wouldn't shut down, until a few days later when it would shut down even if it was on charge. So I didn't use my laptop for a day or two and then started using it again. For a few days, the problem was gone, but now it's back. I did recently update to Windows 10, but I don't know if that's what's causing the problem. Can someone please tell me what's wrong with my laptop? The problem is really annoying. Thanks

The battery status toggles between not charging, not used, and unauthorized battery after it was calibrated using one key. Before that, the battery was working perfectly, lasting close to 5 hours. Now the laptop shuts off when unplugged and the battery status is constantly changing. I've had this laptop for approximately a year now and it was unused and left in an unopened box for the first 8 months.

I am struggling with this for a while now. In Hungary we basically have no Lenovo support. My Yoga 2 is considered old but still a very-very good laptop. The Energy Manager complains that the battery is old and I can see it in its performance as well unfortunately. I tried several sellers on Ebay but I keep getting some crappy quality, usually old, refurbished like (but it does not work at all) batteries. I want a real ORIGINAL Lenovo battery that is BRAND NEW (not manufactured in 2014), that is a real stuff, not just a sticker on the outside, crap in the inside. Could you please help me?

Greetings from Portugal. I'd just like to say that i've found a powerbank that can be used with the 900s (and probably others that use the same charger). The one i found, and can confirm charges the laptop, is "RAVPower 27000mAH Powerstation" that i found on amazon.It's a powerbank with a regular power plug to connect the charger, so it could be called a mini ups instead of a powerbank. Hope this helps people looking for something similar.

Hi everyone! Is it ppossible to buy NEW battery form my Lenovo Yoga 2 Pro 13 Notebook? It uses the L12M4P21. I looked at many places but all the batteries are made in 2003 or 2004. As I know they loose their performance if they sit on the shelf for many years... Is it possible to find really newly made original Lenovo battery for my laptop?

A:I have a Lenovo Yoga 2 Pro 13, I need a new battery... but NEW, not battery that was made in 2004!

Hi Moksa,
 
Welcome to the Community Forums.
 
It may be hard to say as because of the age of the model but you can try calling in EMEA parts sales desk for your region (Hungary 30 722-37-91). On the battery sticker is also the battery manufacturer which you can try but I am not as optimistic for newer manufactured battery. 
 
I would say that as long as they provide the standard battery one year warranty, then it would be a good option to go.
 
I hope this helps answer your query.
 
Regards

My Yoga 3 Pro-1370 does not detect its own battery. At the lower right of the screen, it appears the battery sign empty and crossed by a diagonal line. When I click on it the message "The battery is not used" appears.  OneKey Optimizer says: "No battery is present".

Bought Yoga 900 on 12/30/15.  Recently, it shuts down randomly on battery or AC Power.  Is there a software update I'm missing? It doesn't appear to be battery related since the issue occurs when plugged in too.  I reviewed Power Settings to ensure it wasn't being turned off as a result of a setting.  Thoughts and suggestions are appreciated.

There is a small LED indicator on the side right next to the charging plug that shows orange while the laptop is charging, and then turns green - presumably when the battery is full.  However, I've noticed that the indicator turns green before the battery is actually full.  Just now I saw that it was green, and then checked the status in the taskbar, which showed only 90% battery.   Is this normal?  Are there settings that can be adjusted somewhere for this?  Thanks.

Hey there,
I've been using my upgraded Inpiron 17R SE happily for a couple of years by now. I've even gone as far as buying an 128GB SSD to futureproof it. This is the only drive - besides the DVD drive - currently present in the laptop. However I've had an issue for quite a while:
Whenever I try to boot the Laptop only using the Battery (even fully charged) it Posts then loads Windows and turns of just before the Login-Screen (I can't see it). When I proceed to turn it back on, it Posts then beeps and says that there is a Real Time Clock Error and gives me the option to proceed booting or to enter Setup.
This however doesn't occur when using the Power-Brick. Moreover it isn't always the case. Sometimes the Laptop boots and works fine just using the battery, but then upon opening a Programm (while under battery-power) it shuts of and gives the same error message again. If it decides to work the battery still lasts for 2-2.5 hours.
I'm really confused to what the problem is. It could be a power delivery problem, but it's still the original battery and laptop with only the HDD changed to a SSD.
I'm aware of it being a rather old machine, but selling it is my only hope for getting a new laptop for college, but I can't sell it in this state. 
I'm at a lost and really really sad because of this issue. I'm sorry for any typos or grammar mistakes, I'm a non native english speaker.

Full charge2. Full discharge  The process performed full charging followed by complete discharge of the battery which caused the laptop to shut down.   When I tried turning on my laptop, it could not start.  The battery charging indicator LED wasnt switched on even though the power cord was inserted into the laptop.  I could start the laptop only after removing the battery.   Once the laptop was on, I inserted the battery back in and it began to charge.  After about 50% of charging, I removed the power cord and inserted it again.  Now the battery couldnt resume charging.  I again had to shut down the laptop and repeat the above steps of inserting battery after switching on the laptop without battery.  Only then the battery would resume charging. After this, I decided to allow the battery to charge to 100%.

A:LENOVO Y500 BATTERY NOT CHARGING AFTER USING LENOVO'S BATTERY GAUGE CALIBRATION

 
 
ADMIN Edit - While the original post below is marked as the solution, because service will be required if the battery will no longer charge after performing a battery reset, I am adding a Lenovo update here to confirm.   Normal operation will allow the battery to relearn its capacity characteristics when using the battery reset function.  Typically this is not needed in normal use..   Batteries are equipped with a safety feature that will permanently disconnect them (like a fuse) if cell imbalance or an internal short is detected.   This tends to be statistically infrequent, but also normal, and would require a battery replacement.  (Batteries have a 1 year warranty).   This battery feature can also  produce similar results to what is being discussed in the thread, so it should first be considered by service.   This particular  forum discussion also involves a situation that could affect a limited number of systems, and could lead service to replace the system board during warranty.  
 
If your system experiences these symptoms, please contact service during the warranty period.

Last September 2016 I bought a new Lenovo Yoga 3 PRO, I was quite happy with the battery life and the overall quality of the product. Now, 6~7 months later I still quite happy with screen, audio, materials... but not with my battery life. I give this computer use as home main driver for coding and web browsing, with some photo editing with Adobe Lightroom from time to time, nothing intensive that might heat up the computer on excess. I also try to give the computer "healthy" battery cicles, not leaving 0% battery for long periods neither leaving 100% battery plugged all the time. However, when today my battery seemed not to charge and have been experience shorter and shorter battery life over the last months, I was shocked when I saw on HWMonitor that my total battery capacity droped from 44.000 mWh to 14350 mWh. I could not believe it. Check here: That is too much battery loss for such a short period using my computer! Any idea of what I can do to fix this?

My laptop is 2 years old and within the last 2 months, low battery notifications have stopped popping up, and the laptop shuts down without warning. Within the last week it has been shutting off after 10-20 minutes after I take the power chord out, and the battery never goes above 98% juice.  There's no error messages, and when I looked at the power options, it was set to turn off on 7%, as it has been since I bought it. I haven't updated anything on the laptop since then (it's a laptop purely for Word documents but occasionally I used it for streaming TV when my TV broke) and nothing else out of the ordinary has been happening to it.  I'm incredibly bad at figuring this sort of stuff out by myself, and Googlling it only gave me more confusion because it seems there could be a number of things wrong.  No troubleshooting seems to have helped or given an adequate reason for it, so I'm at a loss at the moment.

I am a content creator, and I use this computer for the bulk of my encoding jobs. Sometimes, when I am rendering or encoding, or even just scripting.
