X240 not recognising battery

Q: X240 not recognising battery

Hi folks, I have an X240 that just ran out of warranty. I was having some intermittent hard drive troubles so I sent it in before the end of the warranty, and it came back with a new hard drive. Unfortunately, it no longer recognises my external batteries - I have two, both genuine Lenovo, one 68 and one 68+. Lenovo won't fix it as they say it's related to the battery latch being broken, but the battery latch has been broken for a whole year and the batteries always worked just fine. When I first got the computer back the batteires weren't showing up in Windows power manager, but I could see them in Lenovo Settings where they were showing as "good" condition. The 68+ had 5% charge and the 68 had about 80% charge. I did a heap of Windows updates etc. which didn't fix it, then tried to "reset" the 68+ through Lenovo Settings, after which it stopped showing up there at all. I now get a message about a battery error when I boot to Windows. I haven't put the 68 back in for while, though I guess I could to see if it still shows up. I'm wondering if anyone has any ideas why the computer might have suddenly stopped recognising the batteries, and anything I can try to try to get my battery life back (going from about 10 hours to about 1 hour makes the computer kind of useless for what I use it for). As I said, I'd be very surprised if it was to do with the latch, as that's been the same for ages. Thanks in advance

Hi I have a Thinkpad X240, i7 CPU and running Windows 7 Pro. It will not recognise a USB 3.0 ext HDD when I plug it in. The light is on and the disc is spinning but it does not show up on the laptop. If I plug in a USB 2.0 hub and then plug the HDD into there it works fine, although obviously at USB 2.0 speeds. If I disable USB 3.0 in the BIOS, it is also detected and works, again at the slower speed. I have tried every update I can find. Through the Thinkpad system update system and drivers direct from Intel for the USB controller. I have updated the BIOS and chipset controller. Does anyone have any suggestions? Many thanks

About a year ago, I replaced the internal battery on my X240 running Windows 10.  For six or seven months, all went well.  Then, from time to time, I started seeing this message: What's maddening is that it doesn't happen all the time.  If the battery had developed a fault, I would expect to see this message every time I started the machine up, but it happens about 30% of the time--and exactly when varies as well.  It can be just after boot time, or it can appear after an hour or so.  On those occasions when it happens, shutting down and restarting the machine sometimes (but not always) fixes the issue.  I've  replaced the external battery (Battery 2) and never encountered this problem with that battery.  The whole thing is particularly annoying because I prefer the 3-cell external battery for size reasons. Before I go purchase yet another internal battery, does anyone have any suggestions?

Tonight I replaced the internal battery in my X240 for the second time.  The first battery, purchased on eBay, worked well for about 10 months; after that, the machine (i5/Win10) started to report that the battery was not found, and would die when the external was exhausted. So, I figured, might as well try again. I just finished the replacement (always remember to shut off the internal battery through the BIOS before doing this!) and all seems well.  The internal battery is charging and, in spite of its official manufacture date sometime in 2013, it's on its first cycle. The battery I removed--the one that had worked for 10 months?  On closer inspection it had a new label pasted on over an old label (see photo).   The new label did not have the Lenovo name on it; the old label did.  This leads me to suspect that the battery was a "reconditioned" (or possibly rebuilt) battery originally manufactured by Lenovo, but just with a new label pasted on. Interestingly, the capacity on the old label reads "min. 1930 mAh," while the new label reads "1910 mAh."  Different cells, or just random errors in labeling? The battery I just purchased (yes, off eBay, I'm cheap) and installed was labeled as Lenovo and carried a correct date of manufacture (that is, the printed date lines up with the date that Vantage reports from the electronics). Conclusions?  I don't really know.  I'll have to see if the new internal solv...

Hi, I have read many people have similar issues for other models other than my Thinkpad x240 20AL but removing the battery won't solve my problem. It is plugged in, it says plugged in but battery is not charging (none of the two batteries this laptop has). I have gone to Driver Manager and uninstalled the 3 Microsoft drivers under battery section. After restarting or scanning for new hardware these drivers appear again and the problem is not solved. I have restarted de computer. Problem not solved I have removed the batter and put it back. Problem not solved. After one night, I switched on the laptop and one of the battery has charged. Right now it says plugged in, charging and it shows already 100% although it keeps charging. The other battery still shows 98% not charging.. I believe this must be a software issue, some power management that prevents the laptop from charging the battery. But where is that software and how to configure it or remove it? I have looked for Lenovo Power Management and similar and it is not installed on my laptop. Anybody knows what I am talking about?

As the subject, I really really want to find where I can buy the internal battery for my dear Thinkpad X240 For years, my ThinkPad 6 cell battery has been drained down about 53% of its design capacity now. I didn't care so much about the internal battery before, but now I find out that it would help much.I have google a lot, but still couldn't find anywhere can order online the internal battery. Or, at least, that online shop not deliver to my country which is Vietnam. In my country, many sellers sell the fake corrupted internal battery. I have been lost about $30 for a lesson from it. That battery I bought, when I successfully put it in my machine and log on, Windows have detected both my 6 cell and it. But, it can not be charged and show unknown capacity. Worse, it prevented the power charge for the 6 cell battery also.

This is a new one for me. My Thinkpad has the internal 3-cell battery and 6-cell hotswappable. The past several days I have noticed that my primary (internal) battery is not being used or included in the % available calculation. Ie., my monitor will say 30% remaining. When I look at each, my secondary batter (6-cell) is at 30%. My primary (internal 3-cell) is showing 97%. I have reinstalled the battery manager, did a gauge reset on both batteries, let my hotswappable run completely down wondering if it is somehow prioritizing usage and would switch itself over to the internal.. although it has never done that before. My laptop shut itself off with 97% still remaining on the internal. I also swapped out the secondary battery. When I first noticed it my internal battery was lower (~40%) but re-charged just fine and has been sitting at 97%, not charging ever since. My only thought now is possibly an error with my internal battery. I'm not too excited about changing it, but it's the only other thing I can think of. Suggestions? Anyone experience this before?

A few days ago my XPS 15 (L502X) started giving an error message on startup and whenever I plug in the charger that reads:"The AC power adaptor type cannot be determined. Your system will operate slower and battery will not charge. This problem might be solved by:- Ensure the plug is inserted completely for best system operation.- Connect a Dell 130W AC adaptor or higher."
Now I know my adaptor is 130W, so that's not a problem. I've also followed all the suggestions I've found so far, including checking the battery health (it's normal), updating the BIOS and checking to see if the adaptor is damaged (it isn't). So, any suggestions? I'm completely out of ideas!

Thanks everyone.

A:XPS 15 not recognising AC adaptor - not charging battery

Hi jbtaylor1103,
Please try releasing the residual charge from the system. Here are the steps:

Disconnect any external peripherals (flash drives, printers, external hard drives) from the computer including the battery and AC Adapter.
Press and hold the power button for 20 seconds.
Reconnect the battery and the adapter. Check if you are facing issue with the system.

 
Check the system using alternate known good Ac Adapter with the system.
Make sure the Ac adapter port is not loose. Wiggle the AC adapter connector and check if the system is able to charge the Battery.
 
Please check the status of AC adapter in BIOS.
Switch On the system and press F2 as soon as you see Dell logo. The system will enter in system setup (BIOS).
Make use of arrow keys and select AC Adapter type.
Please share the status of AC Adapter.
 
Keep me posted with the results. I will be glad to assist you further.

I kinda fixed this issue by not shuting the laptop down if i intended on unplugging it, but putting it in sleep mode, which from he can wake up even with no ac power. One night i left my laptop unplugged, battery connected and in sleep mode the entire night. When i woke up, the laptop had 0 charge in it and couldn't wake from sleep. No leds, no beeps, nothing. Plugged it back in- it powers on normally. The problem is, the laptop no longer sees any of my 2 batteries, unless its on the charger, the laptop acts as if there is no power at all.

Hi ! Over the past two weeks I've spent my time troubleshooting why my recently (used) bought X240 is not charging the internal battery. Short timeline: 1. Bought used X240 in good condition but with dead internal and external battery - working well when using power supply.2. Came home and tested that thing -> both batteries show "0% - not charging" (with Win10Pro installed) *suprise, surprise*3. Ordered both new internal and external battery.4. External battery came 1.5 weeks ago. Installed it and worked like a charm (Battery 2 (external): X%, charging).5. Internal battery came the day before yesterday. Installed it and did not work -> "Battery 1: 53% - plugged in, charging - Battery 2: 6% - plugged in, not charging)6. Waited the recommended 6-12 hours like it was written in the "manual" to get it fully charged.7. Next morning -> Batterystatus unchanged (see point 5) ... It's stuck at 53%. Though the status says it's charging, it doesn't.8. Simply tried out what's going to happen when I pull the cable of the power supply -> Notebook instant off *hmmm*9. As the external battery was obviously blocked from charging by the internal (as it was not charged), I've taken out the internal battery again and et voila, external battery is charging again.I've tried to remove both batteries and perform the "Magic Trick" (press the main power switch for 30 secs) and I've also pushed the "reset" switch on the backside near the battery.

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
 
Shockingly none worked that I found.
 
Only one thing worked for me to my surprise.
 
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
 
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
 
Worked with an off brand battery also.
 
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
 
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
 
Thank GOD for bringing the idea to remembrance!

Howdy HiVolt,
 
I don't think that one will fit.  There are several different lengths of m.2 SSDs and the one in the X240 is 42mm.  The one you linked is longer than that.
 
Up until recently the highest capacity 42mm part was 128GB IIRC, but I think someone has come out with a 256GB 42mm unit.  [edit] I'm not able to verify that just now.  [more edit] Yes I am.  See post below.
 
Here's their compatibility list.  Please note I have no personal experience with this company.

Hey, I really need help. I'm having problems with my laptop. It's a dell inspiron 7559 and was bought around January. Recently I have seen that the battery has no longer been as hot as it used to be when I first started using it. Along with the sleeve on the tip of the screen power adapter (below the part where the adapter lights up) has started to come off, exposing the wires. The battery has continually dropped down its percentage rate ever since I bought it, and it won't go back up. It is currently at 0% battery life and it says when you highlight over the battery icon ( plugged in, not charging). It also happens to show the BIO setup when I start the computer and shows that the batteries wattage and type cannot be determined. In the BIOS setup, the ac adapter type is unknown. The battery has not been through any harsh conditions along with the laptop. I have tried removing the battery, starting up the computer with the ac adapter (which is 130 watts), then adding the battery back, and ac adapter, then turning it on, but it had no effects. If I remove my ac adapter while my computer is on ,it instantly turns off. If someone can support me with this issue, it would be gladly appreciated. Thanks.

A:Laptop battery not charging, battery not identified, 0% battery life

It sounds likely the charge circuit on the mainboard is damaged.  Contact Dell to have the mainboard replaced under warranty.

Hello everyone! Not sure if this is an issue but it's surely annoying to know, that battery N1 drains at 5% and the other stays at 100%. Is it possible for a mixed discharge between both batteries ?After all the LIFE of the first battery (while using battery only power) is shortened a lot! Is there any option in LENOVO VANTIGE that I am no aware of ?I looked everywhere and i can't find anything.. Bios latest update 1.30 Thank you very much!

A:T470s BATTERY 1 drains to 5%, BATTERY 2 stays at 100% (BATTERY PRIORITY)

Sorry  but see below post.  Basically you cant set discharge order.  The laptop checks battery wear and bases discharge order on that.  Many people including myself have asked for a BIOS switch or at least an option on discharge order but nothing has happened so far and I dont think its going to happen either.  I do not speak for Lenovo..

Servicing a X240 laptop, m/n 20AMS0G10F, came in because of no AMT option available in the bios. Called Lenovo Tech Support, case#304TQ58, and replaced the system board. When laptop first powered on noticed AMT option was available, set the time and date, rebooted and ran the Maintance Disk ver 1.86, after input of the s/n and m/n rebooted the laptop and AMT option is now gone.Called Lenovo Tech Support again and was told to replace the board again, replaced the system board, powered the unit on and checked, AMT option was present, input the time and date, rebooted and ran the Maintance disk again, input s/n & m/n, reboot and again the AMT option is gone.Any AMT experts out there? Any way to bring this option back? HELP! Have another that had the board replaced, has AMT now but afraid to run Maintance disk.

Hi,I have the following problem. The 'Fn' key is not working. When I press 'Fn+Esc' to enable the FnLock, nothing happens. But when I switch the 'Fn' and 'CTRL' key in the BIOS, I can press 'Ctrl+Esc' to enable the lock (small green LED on the 'Fn' key is on). But then the 'CTRL' functionality (now on the 'Fn' key) is not working anymore. The shop where I ordered the Laptop already replaced the keyboard but this didn't help. Does anybody have the same problem and can help me? Thank you. Additional information:- I ordered the Laptop in Germany, but with an US keyboard layout (the Shop replaced the german keyboard with an english one)- I updated the BIOS when I received the Laptop (below the BIOS information): BIOS Information    Vendor: LENOVO    Version: GIET72WW (2.22 )    Release Date: 03/25/2014    Address: 0xE0000    Runtime Size: 128 kB    ROM Size: 16384 kB    Characteristics:        PCI is supported        PNP is supported        BIOS is upgradeable        BIOS shadowing is allowed        Boot from CD is supported        Selectable boot is supported        ACPI is supported        USB legacy is supported  ...

I recently purchased a refurbished x240 - I am having 2 issues, which I would welcome help with: 1. the areas with buttons on the top and bottom of the track pad also move the cursor - this often causes an inaccuracy, with the cursor moving slightly before or after pressing one of these buttons - is there anything which can do done about this, or is it a design fault? 2. my computer arrived with no internal battery, just a 6-cell external battery - the seller claims that the internal battery only functions if the external battery is a 3-cell, and that there is therefore no point in me purchasing an internal battery - can this be verified? Thanks for your help!

Memory is also looking fine. Battery is also dead between an hour or 2 as well. Has anyone else experienced this issue? Thanks

I?m unsure if I?m doing the right thing here, never posted anything like this before. The X240 laptop I have was working yesterday, and I put it to sleep so I could continue working later. However now it won?t turn on at all, except the lights over the F1 key, F4 key, and Fn are on. It wasn?t plugged in, but this has never happened before. I?ve also taken out the battery in a myriad of different methods people have suggested online but there?s been no mention of the lights still on.  If if I could get some help, that?d be great. I don?t know much about computers.
