Bad battery life - T450S

Q: Bad battery life - T450S

Hi!Just switched from a macbook air to a T450S. Really like the computer in general but the battery time sucks for me. I use quite heavy applications but I still only get about one hour battery time (even though I have tweaked the battery optimization settings in the Power Manager. According to the specifications when I bought the computer, the batteries are of the type 6-cell litium jon 47wh.Is there anything I can do to make the battery life better?

Hello and welcome,
 
I can't answer directly but it will depend on the combination of internal and external batteries you're running.  There were several options.

To all owners of X1 Carbon 2017 (5th gen).I read all of those reviews where people are impressed by 10+ hours of battery life (15,5h advertised), but I can't really figure out how....!? First time I tested was a normal working day - Firefox (a lot of Flash it must be said), Outlook, Word, Excel, Adobe Acrobat. Nothing really heavy, no peripherals except Bluetooth mouse. Brightness dimmed 1 level below the ideal. It lasted for about 4 hours! I windows's list of apps affecting battery life, Firefox was on 1st place with 32-35% Second attempt - same set of tasks, however less Firefox (no flash) - 7 hours. Now in the middle of a 3rd attempt (using Opera this time) - battery time remaining indication goes over 10h only when I completely stop using the laptop Not many apps running in the background either (Dropbox, Skype...) So my question - do you guys get more than 10h of battery life and HOW? Do you enable "Battery Stretch"? How actively do you use it and for what?

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.

Despite the manufacturer's claim of 7 hours battery life on my Lenovo Ideapad 320S-14IKB - 81BN (S/N: MP1CHQTJ), I only get around 3-4 hours. This is with light usage, Reddit, a little bit of youtube etc. CPU usage was mostly around 0-5% the entire time. This was with the max CPU state in power settings reduced from 100% to 85%. However, I do have the screen at 100% brightness. As a different test, I tried doing (almost) nothing (apart from keeping the screen bright), and got 6 hours out of the battery. Is there a simple solution to increase this? It's only a 30 Wh battery (2 cell). Maybe in the future, a 60 Wh (4 cell?) one will come out for this model?

Hey there,
Yes you read it correctly: I have just received mine, which I purchased because of battery life and overheating and fan noise issues on the Dell XPS 13 i7 7th gen. The 8th gen was supposed to have solved all the issues the previous version was plagued with...
Well... I unboxed it, loaded all of my softwares, installed all the WIndows updates, Dell drivers, you name it. Charged it and started using it. When I unplugged the power cord, first estimate was 4hrs on the Windows battery indicator. Then I installed BatteryBar to have a more reliable estimator. Same.
Later on, I discovered a very strong and very loud fan. Unsurprisingly, the underneath was burning hot.
Got the support team on the phone, whilst I was talking with them, the fan kicked in and I even could give them a glimpse of how loud that was over the phone.
Has any of the lucky owners of the XPS 13 i7 8th gen come across similar issues? 
Sometimes, I am just baffled by the world there is between the promise and the reality....

A brand new system may have an unusually high level of background tasks running simultaneously, such as Windows and other applications checking for and downloading updates, Windows monitoring your usage to optimize technologies such as PreFetch for your usage patterns, etc.  You might want to conduct a battery test after things have settled in a bit more.  The QHD+ display takes 2-3 hours off of the expected battery life, but you should still get 7-8 hours under normal use.  Then again, if you're heavy on WiFi and max out display brightness, you'll get less than that.  The fact that the fans are kicking on also suggests there's an unusually high level of background activity running, so check Task Manager to see if you can find out what's responsible for that.

Hi all, My 2-year old Lenovo T450s is experiencing charging problems. If I plug in the battery charger, it starts charging for a second, it then stops, then the cycle starts again. Needless to say that none of the batteries (neither the built-in nor the external) charge properly. I tried to: (1) buy a new battery charger, (2) unplug the external battery leaving the internal plugged in, (3) unplug the built-in (internal) battery leaving the external plugged in. None of these solutions worked. I then unplugged both batteries and plugged the battery charger, and the laptop works. What do you think? Is it a hardware problem (perhaps related to the motherboard - I can't think of anything else)? Is it a software problem? Thank you in advance for your time! Best, Paolo

A:T450s only works on AC when battery is removed

I cannot be sure without seeing it, but I would guess motherboard charging circuitry.  I am assuming it will not charge while turned off.

Hi everyone, Just received my T450s. Installed the rear battery, then plugged in the power.  On my old T510 I have an indicator showing me when I have power hooked up, and indicates the charging status of my battery.  I don't see anywhere on the T450s chassis that indicates the status of the battery charge. The only thing I will see is the dot on the "i" on the top cover, flash when I connect power.  Surpised there isn't a status indicator. Peter

No, there is no charging indicator on the T450s. By popular demand, Lenovo added one back to the T460s.

Hi, I like that my T450s has 2 batteries. But the thing that bothers me is that the removable battery is drained first entirely prior to using the built-in battery. I've noticed that this increases the "cycle count" of the removable battery as essentially the battery has been completely used. In other laptops this is not a problem as they come with 1 battery and the cells are depleted uniformly.  This has only become a concern for me when I want to use the laptop for long hours without a charger. This would increase the cycle count of the removable battery if done on a daily basis. By doing so will I be ruining the battery life ?  Pls let me know, thanks.

A:T450s - How many cycles can the removable battery ...

Not sure, but I guess this is a bit by design, True the external is wearing more by having more cycles, but this also means that the internal one has a increased live time. The external one will be the first to wear, but is also the more easy one to replace .I already have 2 externals with my laptop.But I get your point and I'm curious about it too. Depleting a battery fully will wear a Li-ion more then not fully depleting it (if my study's where right that is). So it might be true that the less wear on the internal battery does not compare equally to the extra wear caused to the external battery.On the other hand, the extra wear might not be that great to worry about. And this dubble battery design does give us the awesome feature to hot-swap external battery's (which I use quite more that I thought I would).

Hello,
 
I got a T450s, brand new and everytime I am not plugged in (it's a laptop after all) the computer litteraly slows down to a point where it is unusable, a simple key (space, a letter, a number) will usually take 3-5 second and sometimes up to 20 seconds to register, no software is usable, CAD, video playback and authoring, completely useless when on battery. The thing is this is a laptop, I WILL use it on battery. That is despite me choosing high performance in the Lenovo power manager.
 
Anyway I can fix this?

My family, myself are long time Lenovo Thinkpad T users.  I currently have a T 520.  It's fine as it always has been and quite pleased,  but I would now like something much lighter and it has developed a little glitch that doesn't seem reparable.  I will still keep it as a second, back-up laptop.  I just ordered the T460s that is to my liking and right in my price range (got the basic one new from Lenovo for under $800).   But to my dismay and amazement, I keep reading and hearing about lousy battery charge times ranging from 4 to 7 hrs when it is suppose to be at least 10 hrs.  And about all kinds of efforts and ways to increase it with apparently little success.   I have searched several times in this Thinkpad T forum (and elsewhere) on the latest, up to date info and experience regarding the battery and maximizing, extending battery life for the T460s.  I have not found anything beyond around 10/16/16.    As of 2/12/17, I am wondering what battery is now going into T460s, like the one being built for me.   Is it the same as always or something diferent, new, improved? Are T460s users still having the same problems and issues with the length of the battery charge? Has anyone found something, anything that really does maximize, improve or extend T460s battery life? Thanks, Randy

Assuming that they are all designed to fit your laptop, you need to look at the ratings. Basically, you want the one with the greatest Ah (amp?re-hour) as that should last longest. Although this usually means the battery with the most cells, it doesn't always follow. Check their specifications.

Hello,
A week or two ago, I started seeing a pop-up appear on my Inspiron screen (I run Windows 8). The pop-up said that the AC adapter was not recognized, and therefore, the battery would not charge. It was the same 65W adapter that came with the laptop. I hit F2 at startup to check the BIOS, and it said the adapter wasn't recognized. I decided to order a new adapter. While I waited for it to arrive, the battery gradually drained down, but the laptop continued to work while plugged in.
The new adapter came today, an official Dell adapter. I plugged it in... Same error message. Adapter not recognized.
I ran a check on the battery; the system says the battery is fine. I pulled the battery, and the laptop still worked via the adapter. I jiggled and checked all the connections. Couldn't find an issue and couldn't make it work.
I checked the BIOS version and date, and it's from 2013. Time for an update! I downloaded the latest version, but here's the problem: It won't install without the battery sitting at at least a 10% charge. The battery, of course, won't charge with either adapter (it's reading at 1% now). So I can't update the BIOS without some battery life, but I can't make it recognize the adapter and charge the battery without the updated BIOS (assuming that's even the problem, but I'm hopeful that's all it is).
If anyone has any suggestions for how I might make this work, I would very much appreciate it! Thank you!!!

A:Catch-22: No BIOS updated without battery, no battery life without BIOS update...

Please list Dell model number and version of windows. Ex: Dell Inspiron 3543, windows 10
If you don't know, type msinfo32 onto the search box, and then look for System model.....
In the meantime, please check the USB port, where the AC adapter is plugged into system, is loose. You could also wiggle the Adapter's end while checking it in the BIOS to see if the Adapter's type appears.

Hi everyone!

I couldn't find a discussion on battery life in Windows 7, so I decided to create a thread.

I recently installed Windows 7 Build 6956 on my laptop to try it for some time. I'm liking it so far. Using the Balanced power option in 7 I'm getting maybe 20 minutes longer battery life compared to using the Power Saver option in Vista. I'm guessing this is a good improvement since Balanced still allows full performance when needed and Vista cuts performance. I haven't tried Power Saver in 7 yet, but I guess it might give me a little extra time.

Has anyone else timed their battery life?


PS: I also noticed a difference in wake up time from sleep when I open the laptop lid. Windows 7 takes just a second to wake up and Vista takes about 4-5 seconds. Has anyone else noticed this difference?

Hey hethoofd,

I havent got around to running 7 on battery yet, but yes I am suitably impressed by Startup, wakeup, from both sleep and hibernate and reboot times.

The power saving that I have seen so far seems also pretty impressive. I am mainly surfing the forums not the best of tests but it does allow me to see how 7 switches down during periods of inactivity.

Hi wizkid, Vista is more resource demanding, more heat is generated which causing the fan running in full blast often. Also, there always process working on the back ground such as indexing or defrag as such. So, I guess there is not much you can do about it.

I purchased a HP Envy 15 x360 TouchSmart Laptop and the battery life is horrible.  Another way for HP to make money. I do not recommend this product and want to make sure everyone is aware of the additional cost involved with it's purchase.  I have only had this laptop since 2/13/15 and already the battery will not charge.  You either have the option of buying an extended warranty at the time of purchase (as I recently learned) to cover only the first battery replacement or if you choose not to do that then you must pay to have the battery replaced.  It has to be sent in for this to be done or you have to be a computer tech yourself in order to change out the battery as there is not access to the battery from the back of the laptop.  The entire back has to be taken off to get to it. I DO NOT RECOMMEND THIS LAPTOP FOR THIS REASON.  I love the touch screen and the overall function but the battery issue is not optimal.  I can't believe that for the price I paid I now am forced to spend addtional money in the amount of hundreds of dollars to have it working properly.

At first I blamed this on all the added features of sensors, the LTE modem and NFC, etc... But turnign these features off hasnt remedied the battery issues... I am using the fresh windows install and hp setup. All I have added is my same virus scanner I had on the spectre and chrome webrowser. What other Settings exist/ or is this really the best that I can expect from this new laptop. Sincerely,Disappointed

This laptop is advertised to have 9.8 hours of battery life. So far, I've only had a max of 1.5 to 2 hours of battery life. No intensive usage, just emails and typing papers. What can I do about this?

Battery life is bad. Only turns on when the charger is plugged in. It tries to turn on without the charger and it fails. Even when the battery is full and i take the charger out while on it, it will turn of at 100%

If it is a recently bought HP battery and is within 1 year period, normally HP would replace it free of cost.You've to go for replacement, no other solution I suppose.You might be able to do battery test from HP support assistant software.

A:Y40 - Battery life only last 30 min

In response to customer reports of unexpected battery gauge behavior on Y40-70 and Y40-80 laptops, Lenovo determined the battery gauge software is performing as expected. The unusual gauge results being reported are a reflection of the battery reaching end of life.
 
Lenovo has released a Service TIP to assist customers with obtaining battery replacements under warranty, or if out of warranty, to find a replacement battery from Lenovo-approved vendors. The Service TIP can be found here: https://support.lenovo.com/us/en/solutions/sf16-I0023
 
The part numbers for Y40-70/80 batteries are:
Y40 SP/A L13M4P01 7.4V48Wh 4cell bty (Y40-70/Y40-80) 121500248
Y40 LG L13L4P01 7.4V48Wh 4cell bty (Y40-70/Y40-80) 121500249 substitute part 121500251
Y40 CP/C L13C4P01 7.4V48Wh 4cell bty (Y40-70/Y40-80) 121500259 substitute part 121500251
 
To determine which battery came with your Y40 notebook, instructions for removing the bottom cover can be found in the Hardware Maintenance Manual pdf here. An alternative to opening your system (which does not void warranty) is to search for batteries using the model/product number located on the bottom cover.
 
Thank you,

Hi, I have a T430 and it's been great, but I left in in a bag in the cab of my friends truck during a rainstorm, and I guess there's a leak or something, because when I went to retrieve it, the bottom of the bag was wet, and my laptop had moisture around the battery. It's working fine except the battery life is GREATLY reduced! I bought a replacement battery and it's no better. I'm considering taking it apart and cleaning all of the solder points with rubbing alcohol.Any thoughts before I get surgical?
