Excessive battery drain

Q: Excessive battery drain

My question concerns my PCs battery. I am now working on my 3rd battery in less than a month . Everytime a battery drains, I have to reset everything in the cmos, as well as my sound card settings. Since I have little or no experience in this field, any and all relevant help is greatly appreciated. I am running XP , with 1 gig memory , if that is any help. Thanks.

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.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Excessive battery drain

Are you sure the batteries are draining? Are you testing the batteries with a millimeter to make sure that they are dead? Lithium cells are able to last as long as 5 years or more if your getting constant checksum errors I would check the condition of the battery cradle for bad contacts, or cold solder joints, or it may even be a bad CMOS EPROM. Three CMOS batteries in less then a month is not even close to normal.

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 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.

0I solved my previous battery question on my own (without changing any settings FYI). But, now I have a new issue, the battery is draining when the computer is off. Yesterday afternoon I turned it on and even though it was charged to 100% the night before, it was down to 66%. I thought perhaps I forgot to shut down completely, so, last night I made sure everything was off. Today on turn it on it was down to 85%. Thoughts?? It totally defeats the purpose of having a laptop if I'm going to be chained to the AC even when I haven't been using the laptop.

A:Battery Drain

Your battery is dieing. How long has it been since you replaced the battery? Usually when the battery drains almost to nothing in less then five minutes, it means its life is coming to an end and is no longer able to hold a charge.

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.

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.

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.

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.

I may be losing my mind, but I'm 95% sure that I'm experiencing intermittent battery drain while in hibernate mode. For example, I worked all day yesterday with my laptop (Compaq CQ40) plugged in and hibernated with the the power at 100%. I had saved my work, but left three Word docs, two Excel docs, and one Project file open to avoid having to re-open them all to complete a writing assignment. About 4.5 hours later I re-started my laptop to view a movie on my flight, and the batter level was down to 42%!

I think this behavior started within the last 2-3 weeks. I didn't think this was possible! Is there some phantom process running while in hibernation? Ideas?

I have a Dell D400 laptop, bought used about a year ago with two batteries - both of them Lithium Ion 9T119. I run the laptop on mains more than on battery. The batteries used to run for about two hours, but now they only last 30-45 minutes. Is there a way I can find out whether they have come to the end of their life and need replacing, or whether something is wrong with the laptop that is making them drain quickly. The fact that both lost their capacity at the same makes me wonder if it's the batteries or something else.

If the answer is that I need to replace them, are cheaper generic batteries (off eBay) good value, or should I stick with paying Dell's prices?

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.

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.

So I noticed some issues related to X1 Tablet with keyboard cover. 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. This can be resolved by disabling the connection during the standby, but this should be fixed anyway... All drivers and BIOS and keyboard cover FW have been updated to the latest version

The battery life on the Spectre x360 that I got two months ago is absolutely dissapointing. Running the default installation of Windows, I'm lucky to get 3.5 hours of battery life using the HP Recommended powerplan while browsing the internet on a stable WiFi network. I have been working with this computer for two months now and after two hours I have to plug it in. Is there anything that I can do to fix this issue or would my best bet be to contact HP directly? I bought this laptop solely based off of the claims that it could get up to 12 hours on battery and the fact that I'm lucky to see a third of that is upsetting.

Didn't realize it came unplugged toll it died. Left it to charge back up but won't turn on. Will cycle through all the light icons even leave the circle z one on but won't start up. I hear the disc tray cycle for a moment but other wise no noise.  I have removed the battery and unplugged, holding the power button for 10-15 seconds then replacing the battery and/or power and same results. Kind of lost atm.

A:T500 not turning on after battery drain

Pulled the internal battery and that worked for it. Still annoying.

A:Lenovo battery drain during gaming

Welcome to the Lenovo Community !
 
What are the specifications of the charger / adapter you are using (voltage and amperage) ?
 
If it is a low wattage it may not be keeping up with the resource demands the laptop is requiring during gaming.  If the laptop is drawing more power than the charger / adapter can supply then it is drawing on the battery for the extra power.  I had a similar issue with another brand of laptop I owned and resolved the issue by upgrading the charger / adapter from 90 watt to 120 watt.  In my situation it would drain the battery just surfing the net and viewing videos for an extended period of time.  A side benefit of the higher wattage adapter is that it will charge the battery faster. 
 
In checking the Hardware Maintenance Manual for your model it is shows that your computer could have been shipped with either a 45 watt adapter or a 135 watt adapter.  I suspect you have the 45 watt unit.  Please see page #97 of the manual for the adapter specifications.   Here is a link to that manual....
