Hi Yrreg,
Base on my experience i don't encounter any kind of problem while plugging the laptop to the main power supply at the same time using it. In my case i always plug my laptop. My first laptop lasted about 5 yrs before i felt changes in the battery life. Now i have second laptop a two year old same situation i'm doing it. I plug it everytime and keep it open everytime because sometimes i forget to shut it down. My first laptop I change my hard drive after six yrs that was for acer. The second one i have right know is asus. I think they are almost the same.

, as whatsaid, connecting the laptop to an AC outlet with the battery also connected will not cause any problem to the laptop or to the battery.

the battery is not always being charge when the laptop is connected to an AC outlet. the charging of the battery depends on the parameters you set in your laptop. each manufacturer (you forgot to mention the brand of your laptop) has it's own way of setting the parameters of how the battery should be charge. if you move the mouse to the battery icon (normally at the bottom left of the screen) and right click on the icon, most of the time, it will show the apps for setting the charging of the battery. you can then left click on the apps to launch it and changes the setting if needed.
if your using a ThinkPad laptop, just launch the Think Vantage apps and the power management which includes battery charging is in the menu.

all laptop batteries has a maximum life cycle set by it's manufacturer. a properly maintained battery can technically last for 10-15 years. but manufacturers normally set a maximum cycle life for the battery so that you buy another battery from them every couple of years :-). the normal max cycle of a battery is set to 3000 cycles. the users manual of your laptop should have this information.

one cycle means discharge the battery up to some level (e.g. 10% of capacity) and then charge the battery to 100%. so if you charge your battery once a day, then 3000/365 = 8.21 years of usage for the battery. the reason why most batteries do not last this long is because (1) users normally do not bother setting the charging parameters properly and instead just let the default (charging starts at a higher capacity so cycle time is reduce faster) setting of the manufacturer be used, (2) when the battery is charging, most of the time, the user will simply disconnect the laptop from the AC without completing the charging cycle - when you connect the laptop to an AC outlet again, the battery will charge again but with a new cycle.

tips on how to extend the life of your laptop battery:
1. set the charging to start when the battery capacity is <= 10%
2. set the charging to stop at 97%. do not charge the battery to 100% as there is always a possibility of over charging the battery especially if the software of the manufacturer is not that good.
3. the above 2 items will ensure that you maximize each cycle of the battery to it's fullest.
4. when using a laptop on battery power, always make sure that the power setting is on the low side (e.g. screen not too bright, CPU not set to maximum power, etc). this is to ensure that current usage is not set to maximum.

i would also recommend that whenever you buy a new laptop, also look at the possibility (if within budget) of buying a spare battery together with the laptop. you can get some additional discount on the price of the battery if you haggle with the sales person. battery prices is cheaper when the laptop model for it is still new (1-2 years old). battery prices increase when the laptop model is older and their much harder to find. with 2 batteries that you rotate in usage, you ensure that battery cycle will be maximize and you always have a spare battery when you need it most 🙂 ...

hope this info helps ... cheers

Boo!

Thanks a lot for your very useful information!

How can I return your favor?

What about God bless you guys.

God bless you guys! There.

Anyway, if you guys are homemakers, here is a tip which one day you will find useful.

WI don't have housemaids anymore, but there were years when we had housemaids, and as the years rolled by, they got more and more useless and wasteful and hard to find - so we ended up without housemaids anymore today.

At one time we had two girl housemaids; then the water in the toilet bowl in the bathroom downstairs would not flush down quickly; I was sure it was the housemaids, one of them at least was the cause of the trouble.

This was what I did.

Get a length of plastic straw string, and separate one end into several strands of some one foot each in length; tie each strand to a paper clip after unbending it at the middle point between the two U's, so that the two U's make up the two arms of the letter V, with each strand tied to the bottom point of the letter V.

Now, make sure you have enough length (make it at least five feet long) of the plastic straw string, and push the strands into the hole of the toilet bowl, then flush the water tank several times.

You know what I fished out with my gimmick fishing rod?

A toothbrush!

So, that is what one of the two girls did: she dropped her toothbrush into the toilet bowl, and instead of getting it out, she kept flushing the toilet bowl, thinking that it will eventually do down and things would get normalized.

No, that did not solve her problem, she on the other hand just kept quiet, altogether.

Did I scold her, but which housemaid?

I kept quiet also and my wife and the kids, because that was already the time when housemaids would leave you at the first scolding they got from you.

Hope you guys find this idea to be useful.

So, as I know with radios that are powered by non-rechargeable battery cells or by the home electrical current, in order to save on battery consumption, I regularly at home use such radios all the time continuously connected to home electrical outlets, with no harm at all on the radios; when a brown out occurs, the battery cells take over.

What do you experienced guys here say, can I do the same with the laptop computer all the time with its rechargeable battery being charged, in order that I can use the laptop with no annoyance from having to recharge the battery at frequent intervals?

It's ok sir, to use your laptop while it's charging. Ganun din ang ginagawa ko sa old model kong laptop.

Wow! alam ko ganyan din ang ginagawa ko sa smart phone ko. hnd ko xa i fufull charge 90-97% tinataggal ko na xa hnd ko rin xa dini drain but at least once a month i total drain ko xa. Hnd rin ako nagamit ng laptop while charging kc feeling ko na sstress yung battery pag sobrang init na at nakaka liit ng life span nia at possible na masira yung correct charge nia like for example na dapat 3-4 hours cap nia pero naging 1-2 hours n lng, yun yung mga bagay na iniiwasan ko.

Some newer laptops come with a battery life extender. The basic battery extender sets the battery charge level to 80% and the results are good. That is, it appears this does help eek out double the usual lifespan of the common battery. The reasons are not something I'll get into here but if your laptop has such a setting, use it if you can take the hit on battery time.

For me I use it since my laptop is on mains power 99% of the time.
