Good point... though with Optimus the IGP is the only GPU that sends signal to the monitor - I'm not sure how much power HD 4000 uses when it's taking the frames processed by say a 630M and outputting to the monitor. Probably 2D clocks.. so good point indeed.

and so if the cooler keeps the battery cool while gaming, there won't be any battery life sacrificed right?
post #23 of 38
leave it in, more than likely it has a charging schedule that is prevents it from over charging.

I bought a Lenovo in August, it has 2 power/battery settings

1. Maximum battery life: For those who need long battery life and are away from the plug most of the time - this charges the battery to 100% and keeps it there. Slightly discharging to 96% then back to 100%. However in this mode the battery doesn't last very long if you keep it plugged in.

2.Optimized Battery Life: for those who are plugged in most of the time, this charges the battery up to 60% and stops. Then switches over to only AC (plugged in, but not charging) it starts charging at around 56% back to 60%. In this mode the battery health is maintained and kept a 60% charge.

The business versions of Lenovo laptops use the same principle but use 100% or 96% instead of the 100% or 60%. However the option has to be chosen by the user via software. The rules apply even if you turn off your laptop and have it charging

well my cousin has lenovo and he also told me about that option but that's lenovo lol not HP -.- and idk if keeping on 100% all the time would kill the battery or not...i'm planing on getting a powerful cooling fan for home so that the battery temp remains cool.

That's what my Asus does. On AC it spends most of its time not charging. It will usually drop under 95% before starting to charge again.

I will be reveiving a Samsung Series 7 Chronos 700z7c notebook, and its battery is BUILT-INTO the laptop (non-removable).

So I won't have much of a choice in this matter. Laptops with built-in battery SHOULD have some kind of battery wear-reduction features right?

Samsung has some of the best laptop batteries, if not the best. They're rated for to maintain 80% of original capacity after 1500 cycles and 5 years, most batteries hold about half after about 4 years. I'd only worry about not discharging to 80%, charging to 100, discharge to 85.. etc. If you let it have moderately sized cycles (I mentioned this a bit earlier in the thread), no big deal. And its more of a habit thing - accidentally doing a small cycle once or twice (or thrice) won't kill the battery or have much/any effect on it. Oh and don't let it discharge past 5-10% if you can help it - again, no big deal if it happens several times (I must've dropped my battery to 3% 50 times in the past year, still at 90%+ capacity).

As for built-in wear reduction, all Li-on (and Li-poly, and so on) batteries have battery management circuitry that balances the charge across all the cells. This is most importantly a safety feature (if one cell is fully charged, the rest are at 80%, and you try to charge all cells.. bad news). But it also stops cells from discharging too low (ie, battery at 5% overall, all cells will be at 5% instead of maybe 7 at 6% and one at ~1%).

Also lets say that i game all day with my battery plugged in with AC adpater at 100% fuly charged but then at night i take out the AC and watch a movie until battery is dropped to 85% or so and then next day i play the game on AC adapter again with the battery fully charged again. My question is that, charging the battery from 85%-100%-85%-100% is harmful or harmless?
post #29 of 38
ok let me clarify things here, draining and charging a lithium battery from 5% to 100% is 1 full cycle, draining and charging it from 75% to 100% four times is also just a single cycle.

it does not matter if you keep on charging it from 95% to 100%, or from 5% to 100%, what matters is the TOTAL percentage drained and charged over time.

Wait, so what you're saying is that keeping the battery out of the laptop would be bad for the health because it is already draining whereas keeping it charged and using it rarely won't kill the battery life?

I think i get your point...correct me if i'm wrong though
