T420 overheating & battery

• T420s low battery

  I bought a cheap T420s of soneone a few months ago, and if the specifications are good, the battery life is not. Under normal conditions of use, I get about 1 hour and a half, but if I do something intensive grpahics, he died in 25 minutes. Now, since the College begins, I need some strong autonomy.

  I read that people get up to 10 hours of battery life with 9 batteries, and 6 hours with 6 batteries, can someone tell me how to get this performance? If I need a battery (which is highly likely), I would prefer a reccomendation and if possible, no part erased only out of the back, but if this collage party gets a lot more juice for the price, so I'd go with that.

  Features of the laptop:

  I7 - 2620 m

  NVS - 4200 m

  8 GB RAM

  120 GB SSD

  Windows 10

  Number of cycles is stored in NVRAM battery controller and does not depend on when and what OS was (re) installed.

• T420s UltraBay battery 57Y4536 (old) vs A 0, 36310 (new)

  I want to buy UltraBay battery for mine t420s and these 2 options:

  57Y4536 (old) Euro-105

  http://www.Verkkokauppa.com/Fi/product/53279/crsbf

  36310 A 0 (New) - 150 euros

  http://www.Verkkokauppa.com/Fi/product/12878/dhfrs

  The problem with the first battery cheaper on the referenced site above t420s is not listed as a laptop taken in charge. But when I check these:

  http://shop.Lenovo.com/ISS_Static/WW/EMEA/merchandising/PDF/en/T420s_DS_EN.PDF

  http://shop.Lenovo.com/us/sitelets/batteries

  http://www.nbwn.com/products/20937/Notebook-Accessories/battery-power-supply/battery-Lenovo-IBM/Leno...

  The first battery is clearly indicated for t420s.

  I would be grateful if you help me to answer following questions:

  1. is it more age compatible with t420s 57Y4536 ?

  2 are there advantages of the new model on the old model? Is - this block?

  I have defenetelly feel uncomfortable to pay 150 euros for the new model, if the old 105 Euro model works very well.

  Both batteries are basically the same, the 57... We're older, without the authentication chip (does not work in T430s), the 0 a... one is more recent, with authentication chip (also works under T430s).

  I use T420s with the 57Y4536. It's a Li - Pol battery. I bet that the new is also Li - Pol because Li - Pol is the only technology bringing cubic, not cylindrical, which is necessary for this battery.

• Since installing Windows 7 laptop overheating & battery dies quickly!

  I changed my Windows Vista computer software to Windows 7. Everything works fine, except that my laptop seems like it is running on overdrive. It's the gets really hot on the bottom even though I have a cooler running under it, I tried to use the power saving mode and even decreased the brightness. The battery dies very quickly as well. This event began as soon as I started using Windows 7, I ran PC tests to check my battery and all is well. I use my laptop to listen to music and surf the web. I don't know what else to do, any help?

  You could review down the CPU of the computer usage:

  Open Save your Power Options and click Change plan settings.  Then click on change advanced settings.  Processor power management, don't try lowering to 50% just to see if it has an effect.  A good can of compressed air and always using the laptop on a flat surface always help also.

  I have heard about a problem with the gateways and freezing / overheating which could be fixed with a BIOS update from their site.  What is your model number?

• Battery won't charge (my macbook should be tamed?)

  I have a Mid 2009 15 "Macbook Pro. Back to the apple store, I was repeatedly. Show diagnostics all right accept the battery. I was told that my charger adapter was very good. Now I'm on my 4th battery this year. The last three are replacements of ifixit. The initial problem was the battery only takes about 30 minutes without the charger. The first replacement lasted for about and hour off charger. The second lasted almost as long and started swelling after about two months. Now I am on now that lasts about two hours, but does not load, and according to the coconut is overheating battery to about 48 degrees. My normal bed battery status. I have to reset the SMC just for it to recharge. It means unscrewing the bottom plate and remove the battery every time I need to recharge my phone. My fans do work from time to time now.

  I don't know if it's the battery, the age of my macbook, or what. Does anyone have any suggestions?

  An Apple battery comes with a 1 year warranty.  A you bought at Apple, maybe some problems would have been minimized.

  You say that the fans work only part of the time.  This indicates that there is some hardware issues that must be addressed and which can not be directly associated with the battery.

  In order to reset the SMC, you don't have to disconnect the battery.  Read the instructions carefully:

  Use the ones where the battery should not be removed.

  Ciao.

• ioS battery draining / overheating

  I use a 6 16 GB iPhone on which I downloaded iOS 10 a few days ago. I hate this update! The drops of the battery to 100% less than 30 percent in less than two hours of use; and that, no phone call - just by using whatsapp and twitter. I also had days where the battery shows 23% and now after the phone dies. When you connect it to the power supply, it appears directly at 21%.

  In addition, to use the phone for about 30 to 40 minutes in a row, it heats considerably, something that was not the case before.

  If there is a way to solve this problem, please tell. Or Apple must come with a fix emergency. It's a pain to have to keep the phone attached to a power Bank.

  Hello

  Unfortunately, this is a very common on more problem iOS 10 users.

  Here is the link to another discussion: iOS 10 battery draining / overheating

  Hope Apple will deliver a fix very soon.

• T420 unable to charge battery

  Hello

  A month ago I received a brand new model T420 4180F65 with a battery 9 70 ++ (45N1007).

  Yesterday I was no longer able to charge the battery which now remains at 0%, and I can use the thinkpad with the AC adapter is plugged in.

  The battery has only 37 cycles. The application of battery lenovo in windows 7 indicates the battery has an error and can not load, so I am also unable to try to perform a reset of the battery.

  I've seen similar problems here, which was resolved with an update of the firmware of the battery, but there for this model of battery. I am so unhappy that the battery for some reason any already dead? Or maybe this battery also this firmware error?

  / Keis

  For a hardware problem, you must call the hotline.
  I am guessing, but it seems that the battery is defective.

• Battery loose on new T420

  Hi all

  I myself recently got a new T420. Everything except the battery is OK. For some reason any battery 6-cell (55 +) not closely attached with the laptop. (Yes, I move the 'switch' on the 'lock' position). the battery is a little loose, it moves clearly and you can hear it clicking on if I move the computer. I guess it is normal to have some 'soft' but I think it is more 'normal' (and usually I try not to pay too much attention to minor details, but this one is bigger than I can possibly ignore).

  Someone of you have similar problems? Have you managed to fix it?

  -af

  Please note that the solution presented in my photo above turned out be not quite perfect: I noticed that the implementation of the Ribbon to the center stack is part of the flex, pressed by the battery case.

  A better solution is to divide the pile into two piles placed on the left and right of the battery compartment edges: the case is much more rigid. The battery is supported in 4 points in this way, with no sagging.

• T420 battery temprature!

  What should be the normal ThinkPad T420 battery while it is in charge of 10% to 95%? It was close to 45 C. Is this normal?

  It depends on the ambient temperature. This temperature seems to be hot a little uncomfortable.

• Battery life more long T420s

  y at - it a battery of longer life for the T420s. I can't seem to find one on the lenovo site, although it does not find my model number 4171-7fu either. the current battery gives me only a few hours of life.

  any ideas appreciated.

  or just get a second battery of 6 cells. The problem with the ultrabay battery is that they are expensive and their longevity is not large. In addition, it takes about half as long as a 6 main cells and costs the same.
