L440 Battery

My battery is not charging at all. It will run with the AC adapter plugged in but the moment I unplug it the computer dies. I have only had this laptop and battery since july 23rd of last year. It also says it is not charging.

Good day and welcome to the community.
Sorry you're having difficulties.

T440 or L440 for a student - not sure which to buy!

I'd like some opinions please...
I am a student in the UK looking to buy a laptop around late August/early September 2014. I will require the following from it:
Haswell i3 or i5
8GB RAM
1600x900 or 1920x1080 display
Windows 8.1 64-bit
Good build quality
Not too big or heavy, so a 14" display would probably be more ideal than a 15.6"
A touchscreen may be nice, but is not essential
I will be doing a lot of programming on it, so a good keyboard is a must, and I will be doing photo editing and web design on it too, so it needs to be powerful.
I would really like this laptop to last for a long time (and by that, I mean around 5-6 years) and to be well-built. I don't particularly have a budget, but the T440 specced out below comes to £835 and I'd say that is the very top of my budget.
I am keen on a ThinkPad (used to own an A31 and an R40) and looking specifically at the L and T series. I'd like to buy something new and with a Haswell processor.
I've specced out the following machines, do you think it would be worth paying the extra for the T440? Or would the L440 be perfectly adequate and last me as long as I'd like it to last?

I could possibly buy a 256GB SSD for this to speed it up, or upgrade the i3 to an i5 4200M (but I think the only difference between the i3 4000M and the i5 4200M is the slightly higher stock speed on the i5 and the turbo boost?)

I don't think I can spend more than this on a laptop.
My only worry is with buying the T440 is that it may draw attention and I may risk getting it stolen. I'll need to think about that.
Is there any massive reason to buy a T series over an L series?
I have looked that the L540 with a 1080p display, but I'd prefer to stick to the 14" laptops for portability's sake.
I am genuinely interested to see which you think would be better.
Thanks!

I recently acquired a T440s so I may be able to speak on some points, maybe not on others.
My specs:
i5 4200
4gb RAM upgraded to 8gb
Win7 64
256gb SSD
Integrated 4400 graphics
1600x900 HD+ screen
3 cell battery (plus internal 3 cell)
Other stuff..
I do not do anything worth mentioning with photo or video editing, but I do quite a bit of programming, typing, circuit simulation, etc...
The keyboard is very good. I have an R61 with what I always considered to be one of the best laptop keyboards I've used. This one is 99% that good. The trackpoint/trackpad combo works very well for precision visual programming like LabVIEW. The new trackpoint/trackpad setup is a point of contention among Thinkpad users, but I personally like it just fine. It is still WAY ahead of most cruddy touchpads out there no matter what you think of it.
Even though everyone raves about the new IPS 1080 screen on Thinkpads, the 1600x900 HD+ screen suited my needs fine, and I used to funds that would have been put towards the FHD screen to an external 23" IPS 1080 monitor. I will say, the 1600x900 TN screen really doesn't have the best color reproduction. I would not want it for photo editing. I would say either spring for the 1080IPS FHD display on the T440, get an external monitor, or both.
The i5-4200 with 4400 graphics has never left me wanting for more. It does all that I ask of it in simulations without any problems. The only CAD that I do is the occasional circuit board mockup so I can't speak to the effectiveness of the integrated graphics for your needs. I would look further into whether or not the integrated 4400 would be acceptable.
I am very glad i got the SSD. I picked up an external 500GB hard drive to handle backups and excess media. It's kind of a personal taste type thing. If you are OK with spending the extra money for less storage and a little pickup in speed then go for it. The fact that the SSD is not susceptible to damage from moving the computer around was important to me.
I find the computer extremely portable and light, though I am coming from a ~5.5lbs R61 that necessitated carrying around a 2lb power adapter due to nonexistent battery life. I get at least 5 hours out of the battery, usually more like 6 or 7 if I'm not doing simulations.
I don't know what it is like there, but I don't worry about theft in my college atmosphere. I guarantee if you put a Macbook next to a Thinkpad and walk away, the Macbook gets stolen. The Thinkpad is just an under the radar machine, and most students don't seem familiar with them. That said, my computer is never out of my eyesight. If you must leave it in a dorm room, get a good lock for it.
It's possible to save ~$40 and upgrade the RAM yourself. This procedure is not fun, but doable on the T440s. I have heard that the T440/T440P are easier to deal with.

New L440 won't boot after weird video problem

My new Thinkpad L440 just stopped working at the worst imaginable time. I hope someone here will be able to help, though I suspect it may be irretrievably broken in some stupid fluke. Let me give you the details: Maybe five hours before this happened, I removed the battery since I don't lug my laptop around much anyway and wanted to preserve it. I used to do this with my Macbook too, and everything seemed fine, until I started watching this video while downloading some totally legal material in the background using a file-sharing application. The screen would go black, and the computer would be completely irresponsive until I started closing the lid, at which point it would resume functioning. When this first happened, I was able to log on and start working again; it happened again, and I fixed it in the same way. Maybe ten minutes later, the screen went black again and I could not get it to respond no matter what angle I bent the lid. I tried shutting it and opening it again, to no avail. I removed the power connection and reconnected it, to no avail except for the fact that there were two short flashes of the green light at the center of the power button. I re-inserted the battery and nothing changed. So what on earth do I do? I can't believe this is happening right now -- I have so many deadlines!
In any event, it's a Thinkpad L440 bought maybe ten days ago. 64-bit Windows 8.1 (it came with Windows 7, but I installed 8.1 from the DVDs that came with it).
My educated guess would be that it's either my bad luck (and possibly some overheating issue, though I certainly don't think what I was doing was outside of what you could expect a brand new laptop to cope with), or that removing the battery led some internal backup battery to discharge and now it won't start again until it has been recharged.
Grateful for any suggestions.

Lenovo L440 review

I'm new to these forums and new to the Thinkpad world, this would be my first Lenovo. I found little reviews on the L440 or 540 models for that matter prior to purchasing so it was a bit of a blind purchase. So for those who are thinking of buying the Thinkpad L440 it is a great computer. I've only used it for a day but in short this is what I've summed up:
Pros: great build quality despite being all plastic it is strong (as I understand all thinkpad's are), no flex rigid keyboard. In my opinion it is light, not ultrabook light by any stretch but definetely not bulky/heavy, I got the HD+ 1600x900 screen-sharp, nice 16x9 format (for Excel etc, this is my work system), the text is sharp for a matte screen. Great keyboard, plenty of ports USB, VGA, display port (I'll probably buy a display port>HDMI adapter).
Cons: Trackpad seems a bit finicky, I also have a tough time not having tradtional buttons but i'm sure with more use I'll get used to it. I prefer a mouse anyway, Hard Drive is heard spinning/loading (it is 7200rpm after all). Again it's not loud but noticeable, although i'll most likely swap an SDD in.
My build is the I5 4200M, 4gbs ram, HD+ screen, no DVD tray-replaced by optical drive, 6cell battery (can't comment on this, haven't had it long enough) and Windows 8.
That's about all I could think of for now with only a day of use. I love it, the build quality and ease of maintenance for future upgrades. Any questions? Feel free to ask!

The motherboard had to be replaced on both L440s in order to fix this problem.

Battery , time , signal strength bar is not getting displayed in home screen , these will be displayed only when i click on any app. Can u let me know the setting change ?

Did you check the Zoom setting?
Have you tried a reset (reboot)? Hold HOME and SLEEP until an Apple logo appears.
If it isn't Zoom and a reboot doesn't help try Settings/General/Reset - Reset all settings

MBP 15'' 2011 battery lasts only 3 hours!

Hi
I bought MBP 2011 15 inch last week and received it on Monday.
My configs are
Model Name:          MacBook Pro
Model Identifier:          MacBookPro8,2
Processor Name:          Intel Core i7
Processor Speed:          2.2 GHz
Number of Processors:          1
Total Number of Cores:          4
L2 Cache (per Core):          256 KB
L3 Cache:          6 MB
Memory:          4 GB
and I also upgraded to high resolution.
So far, I'm pretty much enjoying my new MBP
But I have one main concern with my new laptop's battery time.
The battry time is really really short!
When I first turned it on, it took 3 hours to drain the battery. (starting from 98% or so)
And I did calibration thing so that the battery runs more "efficiently"
Of course, I didn't expect that calibration would make the battery last longer, but no matter what,
I only get 3 hours of battery life and I'm not even doing something that would drain my battery fast.
I just do simple web surfing and word documenting on about 30-40% brightness (or even lower sometimes)
And I get only 3 hours of bettery time.
So is this because my MBP has four i7 cores or or what?
Previous MBP 15'' models seem to last at least around 5 hrs doing exactly same thing.
And considering that I have been using my MBP only for 5 days or so, I'm worried that the battery life will become even less!
Maybe like 2 hrs?
Is this a particular issue with my laptop, that I can return and exchange to new model or get fixed without fees?
Or is it just built this way that all the MBP 2011 15'' models have this kind of short battery life?

OMG turning off the Bluetooth just gave me like extra 3 hours of battey time! (6 hrs total)
I didn't even know it was turned on in the first place because I never touched it.
I guess bluetooth is on as a default setting.
Thank you so much for advice.
I feel so stupid, but please be understanding since it's actually my first MacBook.
But I'm really glad to find out that I was wasting battery with bluetooth on, and now I can get better battery time.
Thanks once again!

Battery heating

I have the original battery that came with the Thunderbolt. I noticed if I'm using mobile web for maybe over 20 minutes or so, I can feel the battery heating up. Is anyone else experiencing this with the original battery? Is this "normal"? I don't notice it heating up when I just text or use the phone for voice calls. It's past the 14d period when I can return the phone. My laptop was doing the same thing (heating up), until finally it "burned out" the inside and has had to be repaired several times. I'd HATE for the same thing tohappen to my Thunderbolt, especially since I have 2 years with it. (Footnote: I did not purchase the extended warranty.) Help!!!

Download from the market "Battery Monitor" application and it will show you much more information about battery including its temperature. Normailly working battery temperature (not during charging) range is from 80F (27C) and should not exceed 105F (40C). If your battery is getting hotter than 105F during normal operation, you are risking of damaging not just a battery but also internal components of the phone.

I bought the wrong HP battery...!

I bought it online a couple days ago and it arrived today. I opened the package and to my horror the battery didn't fit my laptop. My laptop is a 13.1 inch HP Pavilion dv3. I bought the HP dv3000 Notebook 6-Cell battery thinking it would fit, but unfortunately it didn't. Can anybody tell me what battery I actually need to purchase for my laptop?
Most importantly: Can I return this and get an exchange or something? It cost me 145$, and I don't know what to do with a laptop battery that won't fit my laptop.

Thank you for the link.
As for checking with the vendor... since I bought it online I called yesterday to the tech support number. They talked a lot about some stuff and then told me they don't have the information for what I want. They gave me a number which I am now calling and I've been on hold for 18 minutes and counting. I think I'll try again tomorrow.
I'm sure they'll let me exchange... if I can get hold of them. I sure don't want to be stuck with a 145 dollar piece of junk.

Mid 2010 15" i5 Battery Calibration Questions

Hi, I have a mid 2010 15" MacBook Pro 2.4GHz i5.
Question 1: I didn't calibrate my battery when I first got my MacBook Pro (it didn't say in the manual that I had to). I've had it for about a month and am doing a calibration today, is that okay? I hope I haven't damaged my battery? The calibration is only to help the battery meter provide an accurate reading of how much life it has remaining, right?
Question 2: After reading Apple's calibration guide, I decided to set the MacBook Pro to never go to sleep (in Energy Saver System Preference) and leave it on overnight so it would run out of power and go to sleep, then I'd leave it in that state for at least 5 hours before charging it. When I woke up, the light on the front wasn't illuminated. It usually pulsates when in Sleep. Expectedly, it wouldn't wake when pressing buttons on the keyboard. So, what's happened? Is this Safe Sleep? I didn't see any "Your Mac is on reserve battery and will shut down" dialogues or anything similar, as I was asleep! I've left it in this state while I'm at work and will charge it this afternoon. Was my described method okay for calibration or should I have done something different?
Question 3: Does it matter how quickly you drain your battery when doing a calibration? i.e is it okay to drain it quickly (by running HD video, Photo Booth with effects etc) or slowly (by leaving it idle or running light apps)?
Thanks.

Fresh J:
A1. You're fine calibrating the battery now. You might have gotten more accurate readings during the first month if you'd done it sooner, but no harm has been done.
A2. Your machine has NOT shut down; it has done exactly what it was supposed to do. When the power became critically low, it first wrote the contents of RAM to the hard drive, then went to sleep. When the battery was completely drained some time later, the MBP went into hibernation and the slepp light stopped pulsing and turned off. In that state the machine was using no power at all, but the contents of your RAM were still saved. Once the AC adapter was connected, a press of the power button would cause those contents to be reloaded, and the machine would pick up again exactly where you left off. It is not necessary to wait for the battery to be fully charged before using the machine on AC power, but do leave the AC adapter connected for at least two hours after the battery is fully charged. Nothing that you say you've done was wrong, and nothing that you say has happened was wrong.
A3. No, it does not matter.

Mid-2013 Macbook Air drains battery at hibernate

I recently got a new Macbook Air:
MBA 13-inch, Mid 2013
Processor 1.7 GHz Intel Core i7
Memory 8 GB 1600 MHz DDR3
Graphics Intel HD Graphics 5000 1024 MB
Software OS X 10.8.4 (12E3067)
The issue I'm running into is essentially that I close the lid (unplugged from power and anything else) and overnight the entire battery drains. When looking into the system log, I noticed that the sleep seems to run OK but it's when it tries to hibernate that the issue comes up. It looks to me like it tries to hibernate and runs into an error, tries again, run into an erro, tries again, etc.

This all seems to loop until the battery drains completely. Any Thoughts?

I have the exact same problem. I just installed Mavericks three days ago and I'm having battery drain when the lid is closed.
Does anybody have a solution for this problem ?

Possible Internet Tethering/Battery Life Issue

When either Cellular Data is turned Off, or Airplane Mode is turned On, Internet Tethering (Settings>General>Network) appears to have some process that runs continually in the background (evident by continuously spinning wheel next to the option). The running process has a demonstratively negative impact on battery life (1/3 reduction in ~ 30 mins). The Apple Genius at my local Apple Store and I verified the issue on numerous iPhone 4s that were on display. Turning Cellular Data On and ensuring the phone is not in Airplane Mode stops the activity. But obviously that defeats the purpose of having those options.
So if you are experiencing poor battery life, this might be your issue.

Could this be causing the unexplained usage and data transfer? I have been trying to find what is causing this. http://discussions.apple.com/thread.jspa?threadID=2603718&tstart=0

IPad iOS 8.1 Mail constant network use draining battery

Since updating to iOS 8.1, iPad Mail is rapidly draining my battery. When I go into Mail the network usage indicator (spinning wheel) runs constantly. I left it this way by mistake while traveling and it drained the whole battery with minimal actual usage in one day -- I usually only have to recharge every 2-3 days.
I have checked the battery usage indicator in Settings and it shows that in the last 24 hours Mail used 54% of the battery. I had changed no settings, but went into Mail & Calendar settings and double-checked them, and they were as they had always been. I have three email accounts: Gmail, Verizon, and a company account on an Exchange server. It's the only one that was set to Push, but now I've set it to Fetch like the others and it still continuously accesses the network when I'm in Mail.
This must be a bug of some kind introduced by a recent OS or app update, right? This never happened before, and nothing else has changed in my usage of the iPad or Mail.
One other issue: Mail is not actually fetching new mail when it should. I see new mail show up on Mac Mail hours before it appears on the iPad. Normally email would arrive almost simultaneously on my iPhone and iPad, then a moment later on the Mac. Now the phone is still first, but the iPad lags. The only way I can get the iPad to refresh in real time is to close the app and restart it.
Is anyone else seeing this behavior with the recent update? Any idea how to fix it?

Found a solution at: http://webcamsocialshopper.com/iphone-battery-suddenly-draining-try-this-non-res tore-method
Short version, remove your Exchange account, shut down phone, restart, add the Exchange account back. Problem solved.

FIX FOR: iPhone 4 battery draining fast, phone running hot

I had the same issue many have reported here and in comments on blogs, where their +_battery was draining at least twice as fast_+ as on an iPhone 3GS with iOS 4.
Some threads suggest +_this happens to iPhone 4 when restored from a 3G or 3GS_+, and indeed, that's what I'd done. A few people said that resetting to factory settings and installing everything fresh solved the issue, giving them better battery life than they'd seen on any prior iPhone.
Many of my apps have files or settings stored in them, so I didn't want to have to set everything up again. A fresh install is a real pain.
Deep in an iPhone 3G thread mentioning a similar battery problem after upgrading to iOS 4, someone said they'd deleted all their mail accounts, and set those up fresh, which solved the issue for them. I tried that today, and it worked.
*_BEFORE AND AFTER_*:
Thursday and Friday, the iPhone 4 went from 100% to 15% in under 6 hours. Today, after this fix, the iPhone 4 is at 87% after 12 hours. Thursday and Friday the phone was hot to the touch whenever I picked it up. Today it's always cool. Apps usage and movement among coverage areas on each day have been exactly the same. The only change was resetting up mail.
*_STEPS TO FIX_*:
Do this on WiFi so you can sync and check mail fast.
1. Delete all mail accounts.
2. If MobileMe user, delete MobileMe account, and remove all Calendars, Contacts, Notes, etc., from the phone (so you don't have dupes when you re-sync).
3. Turn off phone, and back on again.
4. If MobileMe user, add MobileMe account first. I enabled all options, even Find My iPhone (Thursday and Friday I had it off, in case it was using power). Wait long enough for contacts and calendars to sync, check to make sure. I use MobileMe mail on Push.
5. Add back each additional mail account. I have 5. I am in a marginal coverage area, so I set these accounts on Fetch Hourly. I also have "Preview 5 Lines" (I think the default is Preview 2 Lines. This doesn't matter.)
6. Go into Mail, go to the MobileMe Inbox, and scroll your way down letting the messages come in. You can see them come in when you see the Preview Lines update, and then scroll some more.
7. Go into each additional mail account's Inbox, scroll your way down, letting the messages come in.
8. Go to the combined Inbox if you use that, make sure all the messages are in.
9. The WiFi activity spinner may remain spinning even after Mail says it is done Checking Mail. This is because other parts of mail accounts are being synced for the first time. Let the iPhone sit in Mail combined inbox until the spinner stops. Quit Mail, go back in, and watch the spinner after it's done Checking Mail. If the spinner doesn't stop after < 5 seconds or so, let Mail sit again. Once it's caught up, going into mail will Check Mail, and the spinner will stop a few seconds after as it should.
10. You're done.
Hopefully your phone stays cool and your battery life reflects the boost from the 20% larger battery. If not, the next step to try is Reset Network Settings, and finally try a factory reset and installing everything fresh instead of doing a restore. Hopefully you won't need to do that. I didn't.

My iphone 4 just started to warm up and the battery is draining quick. Closed everything and reset to no avail. Turned off bluetooth, increased push time and checked location settings for new applications. Weather Doodle was a bit suspicious as it had a purple direction indicator next to the setting. The only other new app I installed was Lego instruct. I disabled one of the 4 mail accounts I had that is having network difficulties, went to airplane mode and still I see %1 drain every 10 or 15 minutes. I'll remove the new new apps and reset to see if it is related to the new apps. If that doesn't work, I'll try email account reset at home wifi and see if that fixes the issues.
Thank you for the information.

First battery charge and current issues?

Hi!
I just bought a new MacBook (2.0 GHz, 160 GB). I have two quick questions:
1. I plugged in my AC adapter, turned on the notebook for about 5 minutes to make sure it works fine, etc, then shut it down to let the battery charge. Would I have lost any battery capacity by not fully charging the battery first? And do I need to let the battery run through a full cycle when I first use the computer to ensure full capacity?
2. Are there any updates/best practices for the 2008 (December) MacBook batteries? I know there was an issue in 2007, but for the new line am I set to go? And is it still best practice to put shut the Mac down instead of putting it to sleep to save wear and tear on the hard-drive/battery?
sorry for all the questions: it has been 5 years since I bought my last notebook so I am a bit rusty/excited!

Since allowing my upgrade to happen, I am unable to double press and shut off apps that are now eating up my battery time. It doesn't "wiggle" anymore to allow me to do this. Any help would be greatly appreciated.

I am a new user and when the phone asked for the upgrade.. I have had a lot of problems. First it eliminated all of my contacts. Also, I use to be able to close open apps to reduce battery usage by holding my finger on the apps until they "wiggled" allowing me to shut the active app off. I cannot do this any more and now my battery time is lasting about 5 hours tops. This is without me using any apps other than answering calls. Can someone please help.
