I got the u45jc Asus laptop and got it because of the good battery life.
Hey guys would you say its better to take off the battery if you have it plugged in? Is it a horrible idea to have it plugged the whole time or should you always take the plug off once the battery hits close to 100 percent?
Also, entertainment mode always as oppose to battery saving mode right?
And should i ever go to battery saving mode? If so, what kind of things should i be doing where i do go to battery saving mode.
Also, how do you turn off the WIFI?
And where do you guys leave the brightness? Do you max it out or put it somewhere in the middle or the lowest?
I take my battery out when plugged in. I have also removed it with the laptop running and have never had an issue. I find it does extend the life of the battery. To turn off wifi on my Acer you hit CRTL+F3. On the U45JC there should be a similar button combo you can press, a switch on the side, or you can do it from within Windows.
do notice that the battery power sub system means you have a UPS which IMO is much more important than the supposed to be benefit of preserving battery life(which I think only is measurable in lab).
I have my batteries in all the time for my notebooks(almost 24/7 for 3+ years) and I haven't noticed any drop in life. That is in sharp contrast with my colleague's machine(exact same model at work) where he only plug in when the battery is almost empty.
In other words, the actual draw down then recharge cycle determines the life, not the supposed to be 'optimal temperature'(may have some effect but not human measureable in my case).
if its running and you pull out battery make sure that its not under a heavy load. My laptop will crash if i pull out battery while gaming/stress test/encoding movies. You don't need to remove the battery unless your battery gets hot. If you touch it and it feels like a hot car in the sun light remove it ^^. Also if you store it make sure its at 40% capacity. But you only need to do that if you are not going to use it for a month or longer. I wouldn't bother reemoving the battery unless you plan on keeping it on AC for more tthan a week. It causes very little damage. I have been doing further research and talking to tech support at a battery reseller and a full charge and partial charge make basically no difference. Your li-ion are rated for 300 full discharges and recharges before they reach 80% capacity. So if you drained it everyday it would still have almost 80% capacity.
About the battery talk; i've always practiced to always plug out the power cord from the notebook once the batt. is fully charged.
I've had issues in the past where my batt. life would become abysmal overtime if the power cord was always plugged in; if the main current would go my batt. would not last not even 5mins. Essentially it seems I messed up the batts. chemistry by having it constantly plugged in via AC power. So my rule of thumb is to always remove that power adapter when fully charged.
But pulling the battery all together shouldn't pose a problem; even while powered on.
There is no harm of removing your battery. I actually recommend it, as heat will kill battery life so if you are planning on being plugged in for awhile, I would remove the battery. Now be careful as if your AC adapter gets unplugged then your laptop instantly powers off. There are also numerous threads here about taking care of your battery.
As stated above, normally a FN combined with any Fxx key with the Wifi logo will toggle on/off or some laptops have a physical switch (becoming less and less common). You really shouldn't be toggling it that often.
I was like your guys several years ago. I had a HP notebook which I used almost exclusively in home and in offices. So I removed the battery and put it in the drawer. After three years my notebook died. You know what, the battery also died because of lack of charging.
By comparison, my wife had a Dell notebook which was designed to mount the battery on when using (due to physical reason). After 5 years the battery life was really bad, say 1 hour. But I could still edit my documents and save them safely before the laptop shut down. Finally the laptop died last month, but the battery was still ok.
You see, my point behind that is:
If you use power adapter most of the time and use the battery only occasionally, most likely you don't need a 6 hour battery life. Before the battery is low, it is very likely you would be able to locate one power outlet. Or if you are frequently on the go and use the battery a lot, why not buy a new one when the original one is dying? It costs only a fractional of the price of the laptop.
It really doesn't make sense to unplug the battery to save it for "possible future use", especially when you are running the risk of power outage and data loss.
According to HP Service its better to take out the battery if you plan on leaving it plugged in for 2 weeks or more, if you plan on going less than that, leave it in
This is true. Most laptops have a power consumption of around 0.1W even when powered off (because of some configurations such as wake up by LAN or wake up by USB, etc.). The battery will slowly drains if you don't use it for a long time.
But you'd better mount the battery when you're using the laptop. It is designed to be so. Advanced power management software would allow you to specify when to charge the battery and when to stop charge the battery.
