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.

Hi, As with many others my thinkpad started to drain the battery while off. I think it came up after i made a bios + other updates that the Lenovo vantage wanted me to do. I noticed the same problem at this thread https://forums.lenovo.com/t5/ThinkPad-11e-Windows-13-E-and/High-Battery-Drain-When-Powered-Off/m-p/4... and it got solved by a bios update. Now i currently run the latest bios i can find for my laptop. Would be greatful if someone came upp with a solution. I'm not able to use the powercord everywhere and it drives me nuts when i run out off juice while traveling.

I have a T480s ( product number 20L8S5F206) that I have from new for several weeks now. I noticed that the battery is draining while the laptop is connected to the charger.The charge thresholds are 40-80 as shown in the attached screenshot.I tried to disconnect the charger, use the laptop till it gets below 40 and then keep it on charge. It can get up to 79% and then starts draining.Any idea on what to do?P.S. I have done a battery gauge reset on the 24th of June.

Hi! Sorry if this issue was brought to the forum before. I checked but couldn't see it.After the latest windows 10 update, my thinkpad which used to be pretty good in terms of battery life is acting like a 20 years old laptop. I cannot use it without charging for more than half an hour any more. Some surface users mention similar stuff. There is no statement from Microsoft. Just wondering if it is just me who noticed this, or are there others who experienced the same issue. https://www.laptopmag.com/articles/microsoft-surface-laptop-2-battery-drain If there are others, how did you fix it? This is really driving me crazy. Thinkpads are usually strong as rock (internally and externally) and very stable. Stability is the reason why I didn't get a Dell XPS. However, it seems like there is no way out when it comes to Microsoft updates.

[I posed question here and answered it in the following message; hopefully this could help those who experience the same issue.] I recently purchased thinkpad p51 and found that the battery will completely drain in a moth. That's charge the battery to 100%, completely shut down the system, boot the computer after 30 days and the battery will be less than 2%. I did the following things and it didn't seem to work. turn off quick rebootdisable the following items in BIOS:'USB alway On''Wake on LAN''Wake by Thunderbolt(TM) 3'unplug any USB devices after shutdownI also did some modification on system config, which still didn't sovle the problem.

A:thinkpad p51 battery drain after complete shutdown

It turns out that the BIOS 'might' be outdated.My BIOS is 1.48 (04/29/2019), there's a new release afterward (1.48-1.10, 05/17/2019). In the readme file, it explicitly says that<1.48-1.10>UEFI: 1.48 / ECP: 1.10- (Fix) Fixed the battery will leak when the system is power-off.Lots of people who have the same kind of issue on multiple machines report that after updating BIOS the batteries stop draining.Also, I've tried many ways and have a feeling that it's less likely due to different settings of the system or BIOS. It could be a bug that causes uncontrollable leak. So I guess that the new release of BIOS should fix this bug. I haven't tried it yet, but think this sounds a reasonable approach. I'll report when I finish the updating.

Battery drain in sleep mode is excessive compared to other Windows laptops. Leaving the office with a full charge, not powering on the unit at home, I come in the next day and the battery is 89%. Same scenario over a weekend - Leave the office with 100% charge, come in Monday morning, having not used the laptop and the battery is 78%. This has nothing to do with the fancy OLED or anything - it wasn't turned on. Hope this can be addressed in a BIOS update. I really want to love this laptop but the short battery life compared to advertised specs and the excessive battery drain while sleeping leave me with mixed feelings.

I have had this X1 Yoga 3rd Generation laptop since May. Sometime in July the battery will get drained at an excessive rate while the laptop is sleeping. I believe it started to happen after some software/driver/bios update around that time. Overnight it would go from 100% charged to 10% (and stops at 10% becaues hibernation kicks in). See below some images for the SleepStudy that PowerCfg.exe reports.   This seems to be the same or a very similar issue to the one reported here for the X1 Carbon that it is still unresolved:https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Carbon-6th-Gen-Battery-drain-in-sleep/m-p/... I have been installing any new updates posted on System Update hoping for this to magically get fixed by one of those updates, but so far it hasn't happened. I'm starting to switch from a happy ThinkPad user that would recommend my laptop to colleagues and friends, to one that may start telling them to stay away from them.

I'm having an issure with a significant battery drain when the notebook is shut down. In couple of days being switched off and not in use, battery loses around 10-15% or even more. I have tried to disable always on USB in the bios as well as the quick start of Windows 10. It didn't help. I still lose  the battery charge. Specifically to investigate the issure I'm leaving the notebook for few days closed laying around aside and then turning it on. Last time I did it the battery was entirely dry - I received a bios warning with the beep about critical battery level and computer didn't turn on normally untill I pluugged the power cable. This shows that battery charge loss is significant and out of control. Extremely frustrated that such a premium computer I bought for traveling and long-lasting off-home usage has battery issure of that kind and can't provide longevity and service it was bought for.Diagnostic tool shows the battery is almost new, 99% of health.

Hi,I recently purchased Thinkpad X1 yoga (1 Gen) machine with 16Gb Ram, 512GB SSD & WQHD IPS (Not even OLED) display with windows 10 pro 64 bit OS.My laptop battery is draining fast and only last for 4 to 5 hours with normal browsing & usage with 60-75% brightness (even reducing it to 50% doesn't give much improvement) and in Power save mode. As per Lenovo it should last for 9 to 11 hours but in reality it is no where near to it. I had also looked at similar issues that has been raised in this forum by other users as well. But I strongly feel that a top brand like Lenovo/Thinkpad doesn't cheat customers by giving false promises for the battery life of  9 to 11 hours without their internal testing, also I feel they would have not be claiming this (9 to 11 hrs) battery life by keeping their screen brightness to dark i.e. less than 50% or 25%. So i thought i could dig deeper to find out the problem. After my initial analysis using powercfg.exe command tool for sleepstudy, the report (i.e. https://ibb.co/hzob7F) shows me some a Ghost application called "Unknown [None]" which comsumes more power and I guess this is the culprit that cases the battery to drain faster. Looks like this Ghost appid takes around 60% of the power compared with all the other appid.  But not sure how to identify this Ghost appid. I have also posted my query in Microsoft forum but yet to get an reply.https://answers.microsoft.com/en-us/windows/forum/windows_10-othe...

I have an XPS 9550 6th Gen running Windows 10 (Just over 1 year, out of warranty).
The issue is when the charge plug is plugged in and hovering over the battery icon it says that battery is charging.  However the battery is not charging but discharging until the laptop switches off.  The only way for the battery to charge again is to deplete the battery until the laptop is unresponsive when the power button is pushed to switch lap top on.  Once there is no residual power in the battery it will start charging again to 100% after which the cycle repeats, discharge.
Things I have tried.
Latest Bios update - no change
Another A/C charger - worked ok for a few days
Replaced battery - no change
Bios settings - reset to default (info related to battery and A/C charge reports all good)
F12 - Dell diagnostics, reports all good
When Battery is disconnected the laptop works normally
The laptop charge socket seems tight and secure
I have searched the internet exhaustively but have not found this same issue reported.  The only feasible way I can use the laptop is to disconnect the battery.
Can anyone suggest anything?
I would also like to disable the battery instead of having to open it up to disconnect, is this possible?
Any help would be much appreciated, thanks

I am a Yoga 700-14ISK user for 2 years. And I had encounter serveral issues with this laptop before (and the service center helped me to fix them) However, now there is an issue I just have now - my battery is draining fast like 1% lost per 2-3 min for light usage (browsing on Chrome or doing my schoolwork either on Microsoft Office or Google Drive) I suspected it was due to my battery wear level. However, as I monitored it, I realised it keep fluctuating (from 19.64% to 42.02%) until I re-calibrate which gives me 38.51% and then 38.71% after a charge to 60%. Is it possible the battery wear level can cause the quick drain in battery?  Is this battery wear level normal? I would also like to point out that I had the battery changed over a year ago and I normally used my laptop for schoolwork and gaming (occasionally now after realising the issue.) I am also going to have an internship (at least 6 months) from July so I am very worried that my laptop can't last long especially its battery. Hence, should I go to a Lenovo service center and request for a battery replacement? Please give me any possible reasons on why the laptop battery starts to drain fast and its battery wear level sharp increase, and also possible solutions for these issues. I would like to know more about it in order to sustain my laptop at least for a year.

Even when the computer is shutdown, the battery continues to drain.In the control panel, in power options, it is configured to go to sleep when i close the lid and after 20 min of inactivity. fast startup is disabled.I read that maybe the intel management engine interface might be the problem, it is now version 11.0.0.1181.Just upgraded bios to version BDCN63WW from version BDCN61WW.If anyone has an idea how to fix the problem please let me know.Thanks

When my battery is less than half full, it will only charge the battery when I turn off the lab top. If I am using the labtop, the battery drains it down to almost nothing despite being plugged in. I have the battery icon running, and it seems that it constantly alternates between "plug in" and "battery usage," but will not stay as plugged in permanently.

I checked the cords and power adapter (to see if it's truly plugged in) and tested different wall connection, but got the same result each time. Is it my battery or is it because of what I am running on the labtop, which requires a lot of power? I usually have 2 or 3 programs running at the same time, including wireless.

is there any "fix" for this problem or do I have to buy a new battery? It's only been 1 1/2 yr.

Maybe someone else knows something else to do but in general I would say you need a new battery. They do reach that point and a year and a half isn't that uncommon for a laptop battery to fail.
You probably all ready know it's the battery it's just a matter of having to purchase another one when it seems like they should run longer than they do. Luck Jazz

My P50 (Xeon, M2000M, FHD) exhibits some strange behavior in regards to the battery and any external monitors and only just started doing so recently. On very low usage, the computer draws about 6-7Whr from the battery. If an external monitor (via DP, TB, or HDMI) is connected and disconnected on the computer, even after I have confirmed the GPU has switched off again, the power usage is double what it was at around 13-14Whr, cutting battery life dramatically. The only way to return the computer to its orignal performance is to completely restart the system (logging off does not work either). This is on a clean install of Windows with drivers and basic programs installed only. Has anyone else experienced this or have any suggestions where to look next? It is quite annoying to have to restart the entire computer every time after an external monitor is used.

Hi, I'm having a strange issue with my P50 (FHD, Xeon, M2000M) where after using external displays, the system will drain an extraordinary amount of power. I documented this previously with no resolution, but have additional details regarding the situation. During regular idle, I usually have around 6-7W of power drain. However, after using external displays (which I use every day), the computer can no longer idle at 6-7W, but idles at 14-16W. I have ensured that the dGPU has been deactivated and that there are no runaway processes eating up network, CPU, graphics, or disk usage. The only way to return to 6-7W power usage is to restart the system. Upon further investigation, when the high power usage issue occurs, the CPU can no longer enter C8 state (higher power savings) and instead can only C6 as the highest power saving state. Additionally, when the dGPU is active, the CPU cannot enter C8 state, so I assume that after unplugging my displays an issue is causing the system to remain unable to enter C8 state.  I would appreciate if Lenovo Staff could respond. I'm unsure if this is a firmware issue or something wrong with my system, but I've had this issue since last August and my warranty end date is approaching.

When the connected standby is entered by closing the cover, it seems the keyboard doesn't enter standby correctly and significantly drains the battery. This can be avoided by using the power button instead. However, sometimes the power button doesn't work (it doesn't dim the tablet even being pushed multiple times), and the battery drain occasionly happens when this happens (shown as USB xHCI drain in the sleepstudy report) Another bug is related to the wireless adapter. If windows 10 is set to keep the internet connection during the standby, there will be severe battery drain, showing nohwdrips.c3 drain, or occasionally nohwdrips.c2 drain in the SystemSoC column.

Hi, I have left a Thinkpad X1 1st gen (20FQ) and a X1 3rd Gen (20LD) off for over 2 months (71 days exactly).Both machines are really off (Windows 10 fast startup disabled), unplugged from everything, and stored at normal room temperature.After that period the battery on the 20LD is at 14% and the battery on the 20FQ is fully discharged. This means that in average the batteries have lost a few percents (2 or 3%) per day. But a quick search online shows that Li-ion batteries should loose a few percents per month when stored. Is the discharge rate on the X1 indicating that something is using energy, even when it is off? I have seen other posts on this, but they report extremely high discharge rates (like 40% per day). In my case it is not as bad, it does not make the laptops unusable, but still I would like to understand what is going on. Would this be considered "normal"?Thanks!

Hi, I think I'm having issues with my HP Spectre x360's battery. it barely lasts 6, most of the times dies after almost 5 hour of use. Before buying, I went through a great deal of reviews which complimented the battery life of this machine, with reviewers claming that it lasted them between 8-9 on normal usage. Also, battery drain continues even when the notebook is in sleep mode. Computer runs on a Core i7 Skylake processor, 8 GB of RAM, 256 SSD, and sports Windows 10 Home 64-bit. Any help is much appreciated, I'm very frustrated and disappointed as to be honest if this goes unresolved I might be forced to buy a new computer because I really need a machine with solid battery life to run my business. Thanks,Hani

A:Battery drain issue

You have a computer with an i7 processor and you get nearly 6 hours of battery life. That is exceptionally good, nothing to complain about. The laptop magazines use tests that do not really replicate actual field conditions. Frankly, most of them are industry shills.  I am not sure what else you could buy that would give better battery life than you are experiencing. You will find other laptops that claim an 8 or 9 hour battery life, but again you are really going to get 5 or 6 on a good day.  Turn down screen brightness, disable wi-fi and bluetooth if you are not using them. Minimize open apps and windows. Not too much else you can really do. Sleep mode still uses power. If you want less drain use hibernation instead of sleep.  if you must have all day battery runtime, buy one of the portable external laptop battery packs about the size of an external laptop hard drive. You will get an extra 4 or 5 hours out of one of those and it charges the battery back up so between your battery and one of those you will get 14 or so hours of runtime.

My new HP Dm3T laptop is great, except that when I turn it off at night, the next day I notice significant battery drain, just from being off overnight.

For example, it was at 100 % charge this past friday night. Then on saturday around 1pm when I turned it on, it had about 91% charge. This was not even a 24 hour time period.

The laptop has windows 7 home premium, and i have heard about some timers that wake up the laptop to scan for viruses and what not.

Does anyone know why my battery would drain like this ?

P.S. I have been using macs for the past few years, and I am re-learning all of my PC knowledge.

A:Battery Drain while powered off ?

Yeah, that happens with any battery, even the car battery. I always disconnect the battery (or take it out) if the car or laptop are not being used for an extended period of time (e.g. more than 2 weeks). Else it will end up dead.

I recently bought a Folio 1020. I notice that the battery drains about 1-2% per day if it is not plugged in using the AC adaptor. I google about this problem and tried the following "fixes":1) disable "USB charging port" in BIOS2) disable "Fast Startup" in Windows 103) disable "Intel Engine Management Interface" driver (I tried uninstalling it, but it automatically reinstall after reboot) but the device continues to lose charge after complete shutdown and not plugged in. Is this normal?

I'm assuming that this thread may not even receive any replies based on the times I've attempted to receive aid from any professional within the Lenovo community. I'll give it a shot anyways. Hello, I've had my Lenovo y40-70 for a little over a year (so that means my warranty is expired--do not tell me to use my warranty to fix my issue). After updating to Windows 10, I've had extremely bad battery life. It would drop from 100% to a hibernating state within the hour. Previously, I've received acceptable battery performance with maybe about 3-4 hours of usage. I've tried updating all my drivers and playing around with battery settings etc. I've uninstalled the energy manager application and am unwilling to perform a gauge reset due to the potential negative effects it may have on the my system. Anyone have any idea on how to fix this issue besides rolling back to Windows 8.1? Oh yeah, I've also tried calling Lenovo support but I was literally on the line for 2 hours listening to a song. Any help is appreciated. May have to end up getting a different laptop if this problem persists.

A:Battery Drain Lenovo y40-70

I have similar issues with my Y40.  Add to that a loss of notification when the battery is low, so the Y40 goes into Hibernate without warning.  Also the data displayed about the amount of charge remaining in the battery stays above 90% most the time while running on the battery, even after 90 minutes of use. Tried uninstalling and updating the Energy Manager. And have tried various adjustments to the power plans. Nothing has solved the problems of unpredictable and erratic battery life, or at least what the Y40 thinks the battery charge level is at.
