Q: Battery 1 : No battery has been detected. Reinstall or recharge the battery to solve [Thinkpad X250]

Battery 1 : No battery has been detected. Reinstall or recharge the battery to solve the issue. That's what I'm constantly getting while using the laptop. The message has been appearing since two weeks or so and I don't know what to do. Battery 1 is not detected by the laptop when I insert the battery number 2: But if I remove battery number 2, battery number 1 works properly. I tried to hard reset the battery, uninstall the battery drivers and restart the laptop, last but not least update all the updatable, but nothing has solved the issue.

Hello!  I am seeking the sage wisdom of veteran thinkpad owners for an upcoming purchase.  I am considering an x250 (i5, 256 ssd, 8gb, 1080P ips non touch, with nothing but a fresh install of Windows 10 pro 64 bit and MS office pro plus) to use for the next two years while I complete a degree(mostly paper writing, web browsing, netflix/youtube etc..nothing heavy). I prioritize a good keyboard, good battery life, light weight(under 3lbs), durability, and saving money if possible.  With that said, I can't deal with laggy performance and lackluster battery life. I "could" buy a new laptop, but am having a hard time justifying spending that much since my usage is so light.  My previous laptop was a macbook air and it served me well, but the keyboard never really impressed me. I sold it, bought a nice Chromebook(12.5 inch screen) and pocketed the change. I have not had a "real" computer for a few years now and it's time.  What say you? 1) Will the above spec x250 provide me with decent performance/battery life for the next two years?1a) What kind of battery life can I expect with this setup and a flush battery?  2) Any other recomendations? I really like the X1 carbon, but the price is tough to swallow with all the issues I am seeing. However, that larger screen sure would be nice on the eyes. 3) Though I would prefer to not get another macbook, with the rumored update to the macbook air right around the corner said to be arou...

So i have a X250 with both internal and external batteries, i recentley upgraded the bios to version 1.27 and reinstalled my machine from scratch. This is when i noticed that it uses the internal battery first, and then immidiately powers off instead of using the external one. I haven't found anywhere in the bios that i can set the priority of the batteries but shouldn't it be the other way around by default?  Any help is greatly appreciated

Hello, Laptop: Lenovo ThinkPad T470 UltrabookType: 20HD I usually do not have my laptop's battery installed when it is plugged with the AC adapter as I use it mainly at home. But today, while I was out, I inserted it (while the laptop was off) and I received the following error message: "Battery 2: A battery error has occurred. The battery cannot be charged. Replace the battery." I've had this laptop for only a year, and everything is up to date. I only take out and put in the battery when the laptop is turned off. According to the battery percentage, it's stuck at 49% and says it's not charging. 49% Not ChargingBattery 1: 100% and fully chargedBattery 2: 0% and not charging I tried checking the battery in Lenovo Vantage, but it just keeps showing the loading animation, but with no info. Does this really mean the battery needs to be replaced (already)? Could it be a software issue? Thanks.

My original 9 cell Lenovo battery pack dropped from 3 hrs to 2 hrs capacity after a couple of years. So when it stopped working, "battery not detected", I thought it was forced into retirement due to low capacity. In fact I opened the pack and all cells were unexpectedly within millivolts and were good to at least 2 Ah. I get an aftermarket 9 cell pack, and it arrives with zero volts. eBay seller quickly sends me another. But the W540 cannot detect it. I order two 6 cell packs from two other vendors. None are detected by the W540.So it strikes me maybe there is something wrong with the connector, and not that the handshakes had failed by these aftermarket manufacturers. Lo and behold, the two positive pins on the laptop were bent, and so was the plastic tongue. It turns out that you can gently force in the battery and hear the double click of the lock, and due to misalignment, normal insertion would bend the pins. No connection will be established if the male pins on the laptop are bent. After straightening them, which breaks the plastic tongue guide, I was able to insert the battery and the battery is now recognized.So if you get a "battery not detected" error, before suspecting the cells or the pack, you may want to check the male connector pins on the laptop and make sure they are all straight. Also check the female connector on the pack as that can be bent, or the female connector pushed into the pack. I believe the alignment of the battery connector is a bit off with res... Read more

I have a ThinkPad T450 with a built-in and external batteries.  Is there a setting in the BIOS or in the Lenovo suite of software where one could set how the batteries behave when they're being used? I'd like for the external battery to drain first so that I could then switch it for a different one before using the internal one.  It's always easier to replace the external battery vs. having to remove the bottom case entirely to access the internal one.

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?

If you are still under warranty Lenovo should fix it by replacing any part. Regards

Can Lenovo explain why they have this policy that once the cells in a Lenovo battery pack drops below a certain capacity (about 80% to 85%), the pack electronics remembers that and then "destroys" the pack by refusing to handshake with the laptop -- so the laptop will no longer recognize the pack?  And replacing the cells or charging the cells will not bring the pack to life as the electronics will continue to refuse the handshake, even with new cells.  This makes the pack unrepairable and forces a purchase of a new pack from Lenovo, way before necessary? Measuring the cells of the pack, I find that the three cells in series register 10.48 volts which is about 3.5 volts for each cell (yes all nine were both capacity and voltage balanced within 1%).  This is way above a cell cutoff voltage of 3.0 volts (or 3.3 V for the purist).  But Lenovo considers 3.5 V to be the limit, displays 0% charge, and forces a recharge of the battery.  At 3.5 V, about 40% of the capacity still remains unused with the cell.  So although the cells have 40% capacity left and may be discharged to 3.0 V, Lenovo considers the battery pack to be fully discharged and forces an unnecessary early recharge. Then to add insult to injury, apparently if the cells continues to hit the 3.5 volt level too soon, the electronics decides that the pack is defunct and then "blows the fuse" and refuses to charge the battery, and refuses to accept an external cha...

I'm not sure when this happened, but the external battery on my T570 creates an error message that is either "No battery detected" or "Battery not supported". I was not able to get a screenshot of the latter, but it happens on occasion. With the error, I am not able to adjust the charge limit.  Originally, the charge level stayed at 70%, which is what I set it to. After reinstalling Windows 10, the charge limit no longer applies and my laptop charges to 100%. As shown in the screenshot, all data values for the battery are present, so I'm not sure why it says that it's now detected. I do not have an internal battery installed.

Hello!

I bought new original Toshiba battery for my M800-107, since my old one has lost a half of its capacity. The problem is, when I plugged this new battery in Win7 says "Battery connected, No charging" and after that "No Battery Is Detected". When I unplug AC, laptop works, but when I plug it in again, still no charging (no existence of the battery). The red battery charging led is blinking, when AC is unplugged, lighting when AC connected. I have tried everything I found on the internet to solve this problem, but nothing worked :-(

I also tried Ubuntu to see if Win is the problem, but the same problem occured.

I have bios v. 5.00.

Don't you know any solution? Maybe - new BIOS if there was any newer?

Thanks in advance.

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!

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..

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.

Hope someone have seen this and found a way of fixing it. The Thinkpad Yoga 14 was bought new from BestBuy, with Windows 10 already installed. A few days ago, after I finally allow Windows 10 to install the "update", the battery started to "disappear", ie the power icon has a "X" and with a message "No battery is detected". The battery driver has a June 21 date, a months after the purchase. So this must be the driver brought in by the Win10 update (note: this is not from Win7, Win8 etc to Win10, but an update of Win10). Removing and reinstalling battery driver did not fix the problem as the same driver is installed again. I also cannot roll back the version as Windows does not show any previous version. I also cannot "restore" as Windows does not actually restore the system: Windows shows the update still installed even after it was "restored" to a state prior to the "update". I also tried to install Lenovo's new power management driver. No help either.  Any suggestions, other than to returning the computer? This is for my son. He'll start his school right now! Thanks!

Let me just start off by saying that my laptop is a piece of junk, lol - I'm so frustrated with it right now. I'd love to just go out and get a new one but I'm a college student and there is no way I can afford too - so that means I have to make this computer last another year and a half for school.

One of the problems I'm having now is that my battery won't charge. I need to be able to take my computer to class and stuff and they don't all have plugs, so I need a working battery! This started about last May when the battery that I had for about 2-3 years started only holding a charge for about half an hour. I figured it was just on it's way out.

Then I had some more computer problems that resulted in a Dell guy replacing my motherboard (for reasons not related to the battery - and yes, my computer is still under warrenty). I figured, I just got a shiny new motherboard, I might as well invest in a new battery as well. So I ordered a new battery online and it worked fine when I first put it in, but now it won't charge.

I don't think it's the battery, it was new when I got it and worked fine until I needed to charge it. I also don't think it's the motherboard, since I just got that replaced.

Does anyone have any other ideas what it could be? Do you think it could be the power cord or something? I don't know! If it's something inside the computer I can get it replaced from Dell but they'r... Read more

A:Dell D600 Battery won't recharge

Remove the battery, and look at the contacts on the laptop and battery. Make sure they look clean. You can try changing the power cord but Dell might be the best source of information for what is involved with charging the battery.

I always assumed laptops had the battery charging circuit built into the motherboard, but it is possible there is a seperate circuit board for charging the battery.

Since its under warranty you might as well take advantage of it.

Get a messagebox saying "battery not detected" and it's not charging from mains. So laptop has now turned into a desktop... as needs plugging in continually... making it almost useless for purpose. This happened exactly after firmware update a few weeks ago. By coincidence the management software also kindly informed me that it could manage the battery better and stop it wearing out by only charging up to 90% - fair enough, but don't treat me like a muppet and disable it without any way to get it back. Tons of Windows 10 updates today (after not being able to use it for a few weeks) but still no battery. I tried F1 BIOS but nothing there to enable the battery (only to disable it). This is frankly a joke - timing shows it's due to the firmware update because the battery was fine and lasted a couple of hours right before. In 25 years of countless laptops, have never had this problem - batteries weaken gradually but don't suddenly lock up and require a paid replacement suddenly. How do we run down our original battery properly before polluting the planet? Phil

Hi.

I have an old Toshiba Satellite Pro P100, a refurbished model, which I got 2 years ago.
It has worked fine ever since I got it, but I went overseas for a month and left my laptop at home.
When I returned I found that the laptop battery won't recharge.

The battery power indicator on my desktop says 0% and it requires constant connection to the mains to work.
I've looked through the manuals, all they tell you is that a flashing orange light means low battery, but not what to do if it doesn't change.
I also looked online, but they don't help either.

What I want to know is whether there is a way to fix my battery or if I need to buy another.

Thanx

Hi

It looks like battery fault.
But check the battery connection firstly.

Remove the battery and after short time connect it again.
If this will not help then you should replace the battery and should test the notebook using new battery.

Hi.Suddenly while using the notebook it shut down without a warning. I couldn't get it restarted so plugged the adapter in. It works fine then. However I do get the notification its not charging or that the powerlevel can't be displayed. When I unplug the notebook shuts down immediatly.I did the accucheck through F2 in the startscreen, it says there's no issue. I callibrated it thereafter manually, (fully charge, unplug and let the battery die, recharge to 100%). After this the notebook worked fine for about a week with the normal battery lifespan of around 5 hours. Now it has the exact same issue again. Doing the manually rebooting every week seems like a little bit of a hassle. Can anyone help me? Btw, I can't replace the accu in this notebook I believe so that's not an option.

My computer is a year old. It was completely fine until I noticed it had stopped charging the battery. After some googling I found there might be a BIOS update I had missed. When trying to install the BIOS update I get a message saying I have to plug in my computer first (which it always is as the batter doesn't have a charge).

The BIOS update program says it wants to upgrade as follows:

BIOS Version : Current Ver.2.60 --> Updated Ver.3.20
EC Version : Current Ver.1.80 --> Updated Ver.1.90

OS: Windows 7
BIOS file I downloaded: bios-20110714132558

Is this a known issue with a fix available?

A:Tecra S11-119 won't recharge battery - BIOS update issue too!

Hi

Are you sure that you have downloaded and used the right BIOS version!?
I read about the similar error message and finally the user used not compatible BIOS.

Furthermore the VAP (value added package) should be installed in order to update the BIOS!!! In you case I would recommend reinstalling this tool too.

But I?m not quite sure if BIOS update will help you to fix the battery issue?
Maybe you need to replace the battery?

Firstly, just to say that this is a great little device but I like many have experienced teething problems during battery recharge.

My bios is is greater than v5, ie v5.2 now.
My experience in Nov 2015 was of battery number two not charging. It seemed to be something to do with the tablet connection, as on a few occasions just unclipping and reclipping seemed to then allow battery two to charge.

At this stage I will say that I primarily use the device like a mini laptop, rarely as a tablet, so am not generally clipping and unclipping the tablet all the time. For a while after it kept charging ok, no unclipping etc, all was well. Then I fitted a leather case, having to unclip the tablet to do so.

This triggered the battery numbr two no charge again. However after several unclips and reclips, plus a power off button sequence (as many have said before) my loveable Toshiba seemed fine at recharching both batteries again. Just a few days ago, though it went back into no charge of battery two mode. I wondered if the leather case was causing a slight uncoupling of the tablet to keyboard body and so removed the leather case, and unclipped and reclipped tablet and keyboard once again, this did not sovle the charging problem.

However closing down from the side power button and restarting several times seems to have solved the problem, again, perhaps only for the moment . . . I wait to see on my next recharge.

Also I have yet to see 12-13hrs available time shown o... Read more

Hi everyone,

My laptop battery seemed like it had loads of life left in it, but one day it just suddenly stopped working and my laptop started saying "no battery is detected". I contacted the insurance people and they came over to check that the battery was dead and that it wasn't a problem with my laptop itself. They confirmed that I just needed a new battery and sent me a new one. Now with the new battery in it is saying the exact same thing ("no battery is detected"), and only working off power from the charger. If I take the battery out and then put it back in again, the laptop says "plugged in and charging" for a few seconds before switching back to saying "no battery is detected" and completely ignoring the battery.

I know that the problem must be with the laptop and not the battery, so does anybody know how I can fix this problem?

Thanks.

Hi there! I've been having a problem with my charger for a while now but it wasn't serious until recently. A month or two ago, my charger went from working completely normally to suddenly not being recognised. This wasn't a big deal, however, because by holding the charger a certain way to the left (kind of twisted) or bringing it underneath the laptop, it would charge like normally. For the past few weeks, however, a notice has been popping up saying

"The AC power adaptor type can not be determined" and then that follows up with a message underneath that stating that I should use a dell charger (this is the original dell charger we got with the laptop)"

This message however didn't matter back then because, by twisting the charger a bit, it would charge and so the message was irrelevant and would only pop up when the charger was plugged in and not twisted (as far as I can remember)

Over the past couple of days, though, i've noticed for my battery sign to sometimes randomly change to an X and, when you hover over it, it says "no battery detected." It will then randomly, a second or two or a few minutes later switch to "plugged in, not charging" and then to "plugged in, charging"; fluctuating randomly and for different intervals of time between these signs. This as well wasn't much of a problem as my laptop was still charging at times and therefore I knew it wouldn't run out.

Now, however, the... Read more

What is the exact model of Dell laptop you have? Look underneath on the label for Model information
For Dells of that time period, you must use a genuine Dell replacement AC adapter or you will get the reduced performance at startup message.... the Dell adapters so I have read, have a chip inside that informs the BIOS of the laptop that they are indeed, genuine Dell adapters.

Read about this issue here- and especially about the little test you can do before your power is all gone- you should do it just once, and I think you will get the "Unknown" message....

http://www.laptop-junction.com/toast/content/inside-dell-ac-power-adapter-mystery-revealed

Note that there is more than just one thing that can be wrong- the motherboard, the adapter chip, the power jack.... Please do NOT attempt the adapter repair at that site.... The power jacks can be replaced by a good repair shop that does soldering on motherboards.

test yours and if you do need a Dell AC adapter they can still be found but it does take some hunting since a LOT of helpful sales sites claim "Genuine Dell Replacements" but I have tried some of those and they did not work but when a real Dell AC adapter was connected, that BIOS message disappeared.

look on the label of the LAPTOP and see what AC Adapter watt rating ....ex: 65watt or 90w..... yours calls for and purchase the correct model.

I can help you find a genuine Dell if needed but test things first. Hope you can do this before the ba... Read more

Hi, I just bought a X250 today. I received it with Windows 7 Pro, and the first thing I did was upgrade it to Windows 10. After an hour of use, I noticed that the battery was draining really fast. I clicked in the battery icon on the system tray and noticed that it says: Battery 1: This battery is not available for useBattery 2: 40% (or whatever) I opened Device Manager and I see two devices listed under the "batteries" section, both of them called "Battery with Microsoft ACPI-compliant control method" (translating from Spanish, which is my system language, so it might not be exactly like this). I guess this means that the system indeed detects that there are two batteries, so it looks like a software problem. I right clicked on both of them and selected "uninstall", and then went to action > look for hardware changes, so that should refresh the driver. After doing that, the "battery 1: this battery is not available" message still appears. I also noticed that there was a power manager application from Lenovo which is not compatible with Windows 10. After upgrading, Windows notified me that this app had been removed and I don't see a W10 equivalent on the support downloads section of the Lenovo website. Any help would be appreciated. Thanks! Pau

A:X250 Battery 1 "is not available for use"

I also tried unplugging the second battery (the removable one). Immediately after unplugging it, the computer shuts down. If I turn it on without the second battery and plugged into the wall outlet, the icon in the lower right corner (system tray) says "no battery found"; however, on device manager I still can see one battery appearing. If I click on "properties" in device manager, it says that the device is working correctly, and there is no sign of any error log or crash report inside the battery properties in device manager.  I tried updating the BIOS and resetting BIOS to defaults, and it makes no difference. I also tried running Ubuntu from a USB stick ("try" option) and it only detects the second battery, not the integrated one.  I guess it must be a hardware problem.

Only recently noticed that Lenovo Vantage is showing roughly half of the original capacity for my main laptop battery (29.01 Wh out of 51 Wh). Contacted the Lenovo support via the MTSA tool then but their response was not only slow but also not really reassuring. After 5 days i got an email with some instructions how to update the power management driver and how to reset the status counter of the battery. Followed that instructions but after updating the driver i was no longer able to reset the status counter. Wrote that to the service contact but that was again 5 days ago... And the most critical point: my battery guarantee is expiring beginning of August... Help!

Hi I bought a 2nd hand x250 online and when i reaached home i noticed battery 1 was no available for use. I contacted the seller and he said that it did not come with one. So it just has an extended external battery that came with it. I am confused because i have another model when has one internal and i bought an external (extended) battery so i have two. I had no idea that some models do NOT have an internal battery. Can i buy one and fit an internal battery myself or are some models not compatible with an internal battery?
