Hello, I have a very lightly used T450 laptop and the internal battery #1 is not being recognized by the laptop.  I have read in other forums on other devices that the connection might be loose.  It is under warranty but I have no Lenovo service center near me. How difficult is it to access battery #1 inside the laptop to check on the connections?  Is there a detailed diagram / instructions someone can point me to?  If I do this, will it invalidate my warranty (I have nearly two years left). Thanks.

A:T450 battery #1

here's the manual:
 
https://download.lenovo.com/pccbbs/mobiles_pdf/t450s_hmm_en_sp40g54937_01.pdf
 
There is no way the battery can become disconnected by itself.  The connection is very secure.  If you remove the bottom cover, the internal battery is obvious and easy to access.  You won't affect the warranty unless you break something taking it apart or removing parts

It is just like my Thinkpad T450 can't see more than one battery. If I click the battery icon I can see that battery 1 is 100 % and full charged but it is like it is battery 2 which is used and when it is below 20 % warning pops up. Battery 1 is still at 100 %. Lenovos test program find both batteries ok and the cycle count for the main battery is 129 and the secondary battery is 400. I am not quite sure which battery is the main battery. Have others experienced this? Using T450 and Windows 10 with latest updates. Peter

Hi all, I recently acquired a very-nearly-new Thinkpad T450 (i5 5300, 8GB) but I have found that under Windows 10 power options it shows the removable battery at 100% (after charging) but the internal battery is "not available for use". I have checked the BIOS for options to activate it without success. Has anyone else encountered this issue? Thanks, Tim

Hello,After shutting down with my battery around <12% when I next tried to boot my power button flashed 3 times and the laptop failed to power up.  I reset the CMOS and my laptop worked again. However, when ever I shutdown or suspended the laptop the power would reboot and the machine would turn back on by itself a couple of seconds later. I have now updated the BIOS but this did not help, nor did turning off wake up from LAN. I once removed the battery but this resulted in my original issue and I had to reset the CMOS again. Now aftering disabling the battery in BIOS, I am again unable to boot even after plugging in the power cable. This time resetting CMOS has not worked in getting my laptop to boot. Now I am also seeing the keyboard lights for fn, mute and mute mic all lit up even when the battery is removed and the power cable is unplugged.  Can I get it to boot again, given the CMOS trick no longer works? Thank You

I recently bought a new T450 which originally had Windows 7 installed. After getting it I upgraded to Windows 10. I've noticed that the battery charges correctly when it's mostly charged, but if I am not plugged in and both batteries (internal + external) get low, then I plug the machine it, the battery won't charge. The system tray will say "Plugged in, not charging" and the power light will constantly blink (sometimes consistent rapid blinks, sometimes long-short blinks). I bought a second external battery with the machine. When I'm in this state, if I swap to the fresh battery the computer will instantly start charging correctly. If I leave the machine charging for a while (15-30 min) then swap in the depleted battery, it will now start charging correctly. It seems as though if I didn't have the second battery I might in a really bad spot. FWIW I've tried installing "Lenovo Power Management Driver for Windows 10" and the "Lenovo Settings" app for Windows 10 that has controls for the battery. Does anyone have an idea of what is going on here? Should I downgrade back to Windows 7? Thanks in advance.

I am becoming more and more concerned about my laptop's battery each and every passing day. When I check the bottom right of my computer screen to check if my computer battery is completely charged, it says "0% available (plugged in, not charging)". I have had to buy two new batteries because of the same thing and they also read "0% available (plugged in, not charging)". When I unplug my laptop from the power source, it turns off automatically. I cannot even bother calling Dell to check this issue for me because I bought this computer off the street for $35.

My question in general is how do I get this problem fixed and how do I keep an eye on how my laptop computer charges correctly (or not)???

Been working fine until a few days ago. When I turn it on it says 163 - Time and Date not set - There is no option in bios to set date Non-System disk or disk error replace and strike any key when ready - Bios cannot detect hard drive So the question is if the RTC Battery is weak or dead can it cause above issues Thanks Chris

A:Question about RTC Battery (CMOS Battery) and System Errors

CWILLIAM83 Hello;Allow me to welcome you to the HP forums!The answer is actually -- yes and no. A weak or dead CMOS battery will prevent the BIOS settings from being saved when you power off the PC. If the default settings work OK with your hardware, then the only thing you would notice is that the clock resets. But, if you customized your settings to see the hard drive, then the default settings might not see it. After you replace the battery, you would have to go through configuring the settings-- again.Good Luck

can you tell me some advice about the battery ? I only know that I should recharge it only if it be under 20%

A:Question about the battery !

Hi.

For a brand new rechargeable batteries this is the right method.

For the moment don't plug it to the power charger.

You need to follow these steps for 2 times.

Use it only with the battery,for now dont run any important program\work let the battery to completely "dry",of course the laptop will shutdown.

Let the laptop off and connect it on the charger,let it few hours to charge the battery.

Unplug the charger,start the laptop,again dont run any important program\work,let the battery to get completely empty (of course the laptop will shutdown again.)

Let the laptop off and connect it on the charger,let it few hours to charge the battery.

Start the laptop,now,

You can use it with the battery and the power\charger the same time.

You can use it without the battery and connected in the power\charger.

The above steps helps to "increase" the battery capacity and charging cycles.

A:battery question

Just leave the battery in, don't worry about it. The laptop is made to handle the power source just fine plugged in or not.

If you go about unplugging and plugging stuff so many time you will wear out the port and the connection won't make contact anymore, you won't be able get a good charge afterward, it goes for any plug. Wear & tear is a bad thing. So try not to do it so much.

A:Another Battery Question?

With modern laptops, the battery can be safely left in and "on charge", as the laptops have smart chargers that will not over-charge or damage the battery.

"Cycling" a LiOn battery by charging, then discharging will shorten the life to an extent, there is a finite life to the number of cycles.

LiOn batteries do not have a "memory effect" like NiCd so cycling is not required. My laptop is used 95% of the time "on power", I never take the battery out. Has not hurt the life of the device, they always tend to die for other reasons, not the battery in my case (3 laptops).

Ideally a LiOn battery should be stored with 40% charge, but as they all have a "self discharge" where they slowly lose charge when not connected that's not a realistic possibility. Leaving the battery in works for me, as you note it automatically picks up if the power goes out.

Can any owner of a P50 with either graphics card comment on system throttling characteristics while on battery power? Does the CPU and/or GPU cut their max clock speed to a hard cap regardless of load--that is, if you're loading both the CPU and GPU, is one device prioritized over the other? Notebookcheck's review (with the M2000M) seems to refer to there being a "55 watt" cap on system power consumption while on battery, without really expanding what happens when you gave the system a CPU-bound application versus a GPU-bound application. For reference, I'm looking to pick up a P50 with the M1000M, i7 6700HQ and the UHD panel.  But as I'm frequently commuting, I'd like to know whether or not the P50 performs like how my old W520 did when I had it: the CPU would work fine, but the dedicated GPU would be severly throttled on battery.

I have almost daily need to operate my Inspiron 1501 on battery for relatively short periods of time. 90%+ of the remaining time it is plugged in and running on the AC adapter power and, of course, recharging the battery.

What I have been doing for the last few weeks is, after the battery is fully recharged, I remove it and continue running on AC adapter power. My reasoning is doing this prevents unnecessary application of recharge power to the battery for the majority of the computer operating time. My thought is this will extend the overall life of the battery.

I would like to get opinions of TSG members on bright idea of mine...
 

A:Laptop Battery Question

Exactly right, raybro.

Fully charge the battery then unclip it & store it away if most of your laptop usage is from mains power.
I've always done that with mine, and I make sure my wife does the same with hers.

Keeping the battery connected when you mainly use mains power most of the time will result in severe shortening of it's useful life & it's ability to hold a charge when you do need it. New, genuine OEM batteries (the only type I would buy) don't come cheap! Fortunately I've never had to buy one yet, thanks in part to the way I look after it.

They won't last forever, of course, even when treated properly, but with care it should last many years.

So, we bought a cheap laptop ($400 - quite nice for the price!) so I could bring a computer to college classes with me. It's working just fine, but my dad is very, very insistent on "exercising" the battery and swears that if I used it while it's plugged in, if the battery is at 100%, that that's very bad for the battery and it'll kill my battery life. So currently I'm alternating, letting the battery go down to about 10% (that's when the computer warns me to start saving stuff) and then plug it in and go back to 100%, rinse and repeat. He swears that this is how you "teach" the battery how to take a charge (?!).

I've never heard of this from anyone other than him. It just seemed a bit odd that using it as often as possible is good for the battery. So I figured I'd ask you guys. I'd dismiss it as him not knowing computers if he wasn't fairly knowledgeable about computers - and because of his job he's used laptops regularly ever since they became common.

It's a Compaq Presario CQ60 Notebook. It cost $399 refurbished at Microcenter - "refurbished" is what they label any return as, even if it was just an overstock, which this one was. New in the box.

This is my laptop. Note that we upgraded to 3GB DDR2.

The battery life with light usage seems to be about 2hr15min.
 

A:Laptop battery question

its true - having a power supply charging the battery to 100% is a problem, the sony machines have a device that detects battery charge and reduces charging after 80% to increase battery life

Yes a Li-ion battery loses some 20% of its capacity per year (depends on storage temperature).

There's absolutely no point in buying the battery in advance. Over time, they will come cheaper and with more capacity. Just buy a new one when you need it.

I have a Dell Inspirion 6400 with a dead battery. It has been dead for quite some time, but I always use it plugged in, so I don't really care if it doesn't run on battery power.

However, last night the battery got really hot so that I felt intense heat through the laptop itself. I removed the battery and everything cooled down and performed as usual.

Is there some way I can disable the battery so that I can leave it in the laptop but not have any power running to it? Would that likely keep it from getting hot or damaging the computer? Would it matter if I just left it in and it kept getting hot?

I don't want it to catch on fire or cook some secret sensitive whatnot in the computer. But I also don't want to have a big hole in the back of the computer or the imbalance of not having the other little foot pad for the laptop to sit flat on the table surface. (whoever thought of putting that on top of the battery was a real genius ). But it seems totally pointless to me to spend $100 on a battery that I don't use and will eventually wear out and be as ineffective as the one I have now. Not only that, but in the not too distant future I would like to upgrade to a newer system so spending more money on something I don't plan to keep indefinitely is silly.

And yes, I'm technologically challenged... but I try to keep up. Any suggestion would be appreciated.

Hey everyone I am buying a new battery for my Hp Compaq 6735s Laptop.

The standard battery I got with the laptop is: 10.8V - 47 Wh - 4200mAh
The one I am looking at buying is: 10.8V - 5200mAh
Battery for Hp Compaq 6720s 6730s 6735s 6820s 6830s NEW - eBay (item 230508215312 end time Aug-08-10 20:52:22 PDT)

They don't specify the Wh (Watt Hours).

The model code I have on my battery is: HSTNN-OB51 451086-3632

Can anyone tell me if that would work with my Laptop? Like will it hurt my laptop if it's a 5200mAh instead of a 4200mAh?

The battery looks exactly the same as mine but mine weighs 339g that one is 479g. Mine is dead so I guess it should be less right?

Thanks heaps for any help!

A:Question on buying a new Battery...

4200mAh means 4200 milliampere hours (or 4.2 ampere hours). 4.2 X 10.8 gives about 45 Wh. I can't answer why it's not 47.

The 5200 mAh should give you 56 wH. It's not unsual for third-party batteries to have higher ratings than the manufacturer's battery, as well as being cheaper.

The eBay battery weighs more than the OEM one because it has more stuff in it. Batteries may not lose weight when they die.

It should work OK with the laptop. Some people shy away from third-party batteries because they are afraid that their compatibility claims will be false.

Should be OK, but the choice is yours. You may not get a reliability report from someone else who bought exactly the same battery.

I have a laptop and to conserve the battery life, I tend to take the battery out and just plug only the adapter in. Is this bad for the computer or the adapter?

A:Battery/Adapter Question

No harm done. The only thing to worry about is because you are taking the battery out you have a greater chance of bending the prongs for the battery connection. Another thing to watch out for is that if it gets unplugged...you are hosed (as this will cause it to immediately shut off). Other than that it's fine.

Some newer model laptops actually come with an option that when it is plugged in, you can disable battery charging. So the power just goes directly to the computer instead of through the battery then to the computer.

Hope that helps.

Many battery manufacturers do not recommend long term ( months at a time) trickle charging. If trickle charging is used then the charge rate should be very low or only intermittent. The best smart chargers will only send an occasional pulse charge to the battery once it is charged. They do not apply a continuous low rate of charge. Some battery resellers state that applying a continuous trickle charge of about 1/10th the battery's capacity is not harmful. However, we have not seen any battery manufacturer condone the practice.

It is better to fully charge batteries and then store them fully charged in the freezer than to leave them on trickle charge for very extended periods of time.Click to expand...

Howdy folks... My Dell Inspiron 1501 laptop is doing a strange thing. Immediately following POST (i have the diagnostics screen enabled) and before the Dell blue bar, I get a message that reads something like this. "WARNING. The battery is not recognized and it may not be able to be charged. Press any key to continue" It will just hang there until a key is pressed.

I've had this once before when the original battery was dying after about a year and a half. At that time it would charge OK, but would only last about 30 minutes. Purchased a new battery (not from Dell) and warning went away with normal boot into XP. That was about 6 - 8 months ago.

This started happening when recently I unwittingly unplugged the AC adapter with the machine on and the battery ran completely down. Been doing it ever since. The difference between this event and the last time is again the battery charges normally, but now lasts over 2.5 hours when running on battery power. So it does not constitute a functional problem, just a pain in the butt to have to remember I have to hit a key to boot.

Anyone got a clue other than to buy another battery. (hardly seems worth it)

Is there any real difference between a 29+ and a 44+ battery when used in an x220 laptop??













Solved!

Go to Solution.

A:X220 battery question

'afternoon.
 
no difference in usage or performance.
the 44 is the X230 battery, that also works in the X220. it's got an extra chip in it that the x230 uses to allow charging.
the 29 is the X220 battery, that will power the X230, but will not recharge in the X230, because it lacks the chip.
 
my X220 came with the 29+ 6-cell. i ordered a 4-cell from the Lenovo store and received the 44. works perfectly.

Do any of you know what the typical overall battery life for notebooks are?

I'm having an issue with my Sony VAIO notebook that I purchased in 2001 where, despite it being fully charged, it only lasts for about 10-20 minutes off of the AC Adaptor. Must I simply buy a new battery or is there a problem with the notebook itself that requires further attention?

If a new battery is a must, any preferences among you (seeing as how you are all far more knowledgable than I)?

Battery life

Battery life per charge obviously various a lot between machines and the sort of usage it has. Around 2 hours should be expected. My Thinkpad does nearly three hours on average.

I just bought a Lenovo Ideapad Z570. It has two options for the battery charging. One is it charges the battery 100%. The other it only charges 50% and supposedly if you don't use your battery very often, it will extend the life of it. I don't use the battery very often, but would like to keep it charged 100% in case I need to use it. I would like to get an idea if the 50% option really saves that much on the battery. Any help is appreciated. Thanks,

I have a Z560 Ideapad and only charge it 100%. I don't use the laptop that often, but I haven't had any issues with the "100%" charging.

i have a laptop running Win 7 Home Premium and wonder if one should leave battery in the laptop once it is fully charged. What is generally the recommendation?

Any input would be appreciated.

A:Win 7 laptop battery question

The battery is made to be left in the PC all the time. It will increase your battery life if you let the battery run almost empty every month or so then recharge.
