Turning on the adapter and use the notebook at the same time will affect the battery? Or should i just turn off the adapter and use the battery instead?

I scared i will spoiled the battery if i turn on charger and use the notebook at the same time.

Sorry for such a noob questions..

Well, its ok. Everybody has to start from somewhere low b4 they can be pros.

Yup. There is something called Battery memory effect. Look it up in google for more info. If you want to make your battery last longer, you need to use your battery till its fully empty before recharging it. If not, some current will stay stuck in the battery, causing short battery life.

Then for my other question which is charging and using it at the same time, will affect anything?

Nope, other than that, its perfectly safe. One more thing, do not take out the battery when the power is plugged in and the system is on. If unlucky, will burn the power supply. Happen to me once. Cost me RM300 to get it fixed. lolz

owhkay then.

Thanks alot for helping. =)

no prob

got some of my humble opinion to share.

before you do what Oretega says, check what type of battery you are using. NiMH (older batteries) are proned to memory effect while Li-Ion batts do not have any memory effect. if you are using NiMH or NiCad (nickel based) batts, then no prob. If you are using Li-Ion batts, do not pratice what he said.

chances are, modern batts are li-ion. sorry dude, but that's the truth.

For Li-Ion batteries, do not do practice full discharge and full recharge. It will shorten the life-time. Li-Ion batteries prefers trickle charge or chargs when it is used from 10% - 30%. If you practice partial recharge or trickle charge, the charging and sensing system will be confused and calibartion would be needed or the meter would indicate a wrong battery status. This is sometimes known as the "digital" memory effect. Thus, it would be a good idea for a full-discharge (use till empty) after 30 charges to calibrate the battery meter.

For Ni based batteries, you'll need to do a full discharge since it is prone to memory effect.

Here are some notes:
1. Trickle charging is the best for Li-Ion. Minimize full discharge/recharge cycles. For NiCad or NiMH, you'll need to do a fully discharge to avoid memory effect. However, trickle charging is dangerous if the charger do not monitor the voltage levels correctly. This may lead to overcharging.
2. Do not overcharge. Normally, your computer will take care of that. If it overcharges, the battery cell will be permenantly damaged.
3. Minimize deep-discharge (over discharge). Li-Ion batts are not meant for deep-cycle discharge.
4. It is good to maintain the battery cool. This prevents aging of the battery cells.

@ Nezs,

I read your guide on How to preserve Li-Ion batteries, good habits to not kill your batt...


but can you please care to explain more on "Trickle charging" ? because I don't get it.

are these statements true?

Anyway, I think he's basically saying that you do not need to fully discharge (or "drain", as we sometimes call it) the battery before recharging it again.

Therefore, its okay to plug in and start charging the battery when its, say, 70% capacity. (:

oh I see, thank you.

My cousin Inspiron suddenly cannot ON.
Call dell to check...
say power circuit on motherboard got problem,
replace for free since under warranty.
Dell say: Once battery full, stop the charger...

hello. Basically it is adviseable to maintain AC adapter plugged-in with the battery in the notebook?
