No but someone in here said to a similar Q the other day to try letting it completely discharge and then recharge it.

That actually works trilby. Was mid-way through a mobile phone charge when I had to go out so unplugged it and took the phone with me. Following that I found it only lasted a day, at most, when usually it would last 3 or 4 (I don't use the phone a lot). I decided to test the discharge theory and now it is lasting 3/4 days again; I kid you not!

It was me with the discharge theory as I am KING OF THE GEEKS!

There are two reasons for that. It's less common now but some battery technologies (Ni-Cd being the worst) have an inbuilt chemical memory effect that you get if you kept pottering about without a full discharge. Best way to attempt to fix this is a slow full discharge then a full uninterupted charge. But modern batteries are likely to be Lithium based so aren't so bad for this (but the ones in say your wireless phone might by NiCd and if so would be).
The other one isn't intrinsic to the chemicals, my understanding is modern complex batteries can have self calibration circuitry to track their own .. charge holding ability and if they never get fully discharged/charged it can confuse what is empty and what is full. |

the OP did not state what type of laptop or what kind of battery so hard to help ,prob be down to laptop battery management settings although without knowing make/model no advice can be offered . Battery “memory “ is a term used but not understood by most who use it .The main problem with laptop and power tool batteries that are NiCd is the charging circuit ,for cheapness they (mostly) utilise a series charging circuit ,a one size fits all approach and the good and the bad are all treated the same ,the strong set the limit and the weak suffer from being asked to give what they don’t have and subsequently let the team down .The newer tech allows for each cell to be treated as an individual and the cells are equalised ,often they fully charge and then draw down but as there is so many diff types of lithium batteries now and that is a a very simplified explanation and for many reasons ,usage ,temp ,charge time ect ect it’s now a very complicated technology that fewer and fewer people really understand .If individual cell management was applied to all batteries it would prolong life and give better performance but cost is the issue .Also lithium cells require this style of management for safety reasons but NiCd packs would have lasted much longer if it was applied .Most folk would have used a NiMH battery charger and this was individual cell management at work with varied types of charge used ,but issue was fast charge v slow trickle ,it’s all about fast charge now but slow is always better for longer life .Many laptops cycle continuously rather than use the AC adapter ,this is stupid imo but unless you know what state of charge and what temp to store the battery it could be counter productive removing battery for long periods ,some suggest 80% charge and keep in fridge but you need to identify the cell AND the charge circuit before being able to make that call or you could do harm . No easy answers answers with this stuff .

Off out but have a look into it when I get back ,might have one of them Samsung notepads kicking around think I used it without the battery although it had problems updating windows due to Samsung’s own updates causing conflict,fobbed me off with a load of bull ,swore I would never ever buy another Samsung product again ,is the charging jack ok ? Think mine failed and I opened it and extended cables and put my own conections in ,keyboard failed as well ,think they have three settings for power management but trying to remember what the battery choices were ? Look into it and see what I can uncover ....would you take a tenner forrit ?
 could use the spares |

Have you tried turning it off an on again?

So is the laptop working ok without the battery clipped in ? Had a quick look and think you need to look at battery life extender settings and toggle off but Samsung has its own diagnostic claptrap ,you run this programme from the Samsung settings , Do you have the Samsung stuff installed ? Also you can access bat life extender settings from windows . What version you on ? The battery has a temp chip in it and could be the old one was overheating and laptop has reduced the charge to prevent damage ,batt power management settings is worth a look ,will be a procedure for a new battery and some way to get reset ,run the Samsung diag claptrap tool thingy .

let the computer run down yesterday ,,disconnected the power supply , took the battery out, inserted the battery this morning,, powered up, now battery wont charge over 19%.. seems every time i do this procedure , the battery loses less power,
|

By:
Is this the same symptoms as previous battery ? You say you have selected balenced ? This is machine power options ,how about the battery charge options ? There is battery life extender via windows and access via bios on startup ,think it’s f2 but you need to check ,what is Samsung diagnostic saying ? Everything ok o pressume ? Have you considered a restore ? Have you had this since new ?
|

By:
Can find bios on my laptop.battery set at balanced..when you say restored do you mean just back to the time I started having problems with the battery.thanks for replying .

This may help.
Calibrate your Battery Perform the following steps to calibrate your battery: • Connect the AC Adapter. • Fully charge your battery (99%-100%). • Disconnect the AC Adapter. • Shut down the computer. • Restart the computer and press the ESC key when the power light turns on. • Select F2 System Diags from the Startup Menu. • Select Full Hard Disk Test. • Leave the system on and allow the battery to fully discharge. • This step may take up to 6 hours to complete depending on the battery. • Connect the AC Adapter. • Fully charge the battery (99%-100%). • Keep the AC Adapter connected to the computer for 2.5 hours with the battery fully charged (99%-100%). • Power on the computer and Launch HP Battery Check to validate the calibration was completed successfully. If the battery status is still "Calibrate", you will need to complete the steps again. If the battery will not calibrate the second time it may need to be replaced. |
