... How better manage laptop battery for better conditions and battery long life: if I work at home near outlet, should I use Power Supply constantly plugged in? Or I should fully charge battery, then disconnect Power supply and work from battery? Regards If a battery is being stored away from the PC for a while, then it is recommended that you charge it to 40% and keep it sealed in a cool place. If a battery is being used regularly, then there are mixed views on the best way of extending their life. Some say that when working from mains power, the battery should be removed from the laptop, others say to leave it alone. I have had a Dell 6400 for 7 years now. The first battery died within 18 months - I never removed it from the laptop and used the laptop on a mix of mains and battery, occasionally completely flatenning the battery. I replaced the battery with a new one from eBay and it is still going strong with exactly the same usage pattern as the first. I guess there is a mix of qualities out there with laptop batteries and not matter how well you treat a duff one, it will fail and no matter what you do with a good one, it keeps going! |

Unless the battery is low.. - it doesn't matter if the laptop is switched on or not, the battery will still charge. When the battery is full, the charging will stop. Not always, and all rechargeable batteries have some level of self-discharge. Every so often, it will drop enough to trigger the charger. Many chargers never fully "stop", they still put out a trickle charge. Good rule is to never leave an unused laptop on the charger more that a few days, a week at most, and (try to) use up at least 3/4 of the charge before you recharge it. The power supply adapter will get warm/hot whenever it is being used - this is when it is charging the battery, running the laptop, or both. If the laptop is off, then the battery will charge for a while and when the battery is full, it will not require mains power any more and the power supply should cool down again. Some power adapters get hotter than others. As in starting fires.. I think every major laptop manufacturer has had at least one recall due to that. Technology has improved both chargers and batteries vastly, but the amount of time we use laptops has increased heavily as well... so it's about a wash. -- "**** this is it, all the pieces do fit.

Remove the battery from the laptop and store it in a cool place. This will make sure the battery lives for the longest time. 2. Leave the battery in the laptop and hope that it is a good one (mine has been like that for 5 years now and still holds a full charge) 3. Forget about the battery because you don't use it anyway - just leave it in and your laptop will survive a power cut! |

As I said, I think that if the laptop is plugged in to the mains, it will use mains power and won't use the battery at all. That is correct. With a well-designed properly-functioning the battery and charging circuit will charge if it needs to and will stop charging when it is full. If the mains adapter is connected then it will provide power to the computer -- there is no 'switch' involved. Over the years I've come to the conclusion that laptop batteries are made removable for a reason -- they are expendable items. I've owned battery-run computers ranging from a 286 machine which used a bank of D-sized nicad cells that weighed about as much as a bowling ball, through every technology down to the lithium cells in my current HP. The one common feature to each of them is that they all will go bad eventually -- the modern ones are simply much easier to manage than the old. I leave my laptop plugged in most of the time and let is sleep as it wishes so that it can automatically back itself up to the server every night. The battery life seems to be pretty much the same after three+ years of being used this way so I assume that HP got the charging circuit right in this model. But when the battery does weaken and doesn't provide sufficient life for the rare times I need to use it on the road then I'll simply buy a new one and smile to myself as I think of the amount of time I've saved over the years by not obsessing over care of the battery. |
