Well it's been well over 3 months since I've owned my laptop and from what I've seen I'm assuming unless you have something like the absolute top-end Alienware laptop or something, you won't get much battery for gaming. Can anyone give me any sound advice on this? I haven't actually tried playing games but I only get like two and a half hours of battery life even on battery saving mode without the Power supply. So will I even be able to get more than half an hour even if I play my games on the lowest possible settings? Or is it not possible unless I go so far back as to be playing DOOM 1 and 2?

Actually, alienware laptops have TERRIBLE battery life while gaming.

Most full-sized laptops will be bad at gaming if you want battery life. You'll be lucky to get an hour, settings shouldn't really matter since either way you'll stress the hardware and suck battery like no other.

Any laptop is going to use a heck of a lot of power, and given that batteries are only finite in their capacity it's only going to last you so long. I'm surprised you get two and a half hours, it's probably because the battery hasn't had a chance to deteriorate yet.

If you desperately need more power add more batteries. Get an inverter, connect a couple of 12V batteries and you can supply mains voltage to run your laptop off. The drawback is that the extra batteries are heavy. Still, that's the issue with gaming on a laptop not connected to the mains.

Try turning off WiFi when you don't need it. That should extend battery life by a few minutes at least. Turn down screen brightness as far as you can without hurting picture quality. Don't run any unnecessary background processes. Beyond that, there isn't much you can do to extend your battery life.

My laptop has a Core i7 740m processor, GeForce GTS 360M with 1gb ddr5, 4gb of ddr3, and an 18.4" 1920x1080 screen. For simple web browsing I get about two and a half hours of battery life. Watching a Blu-ray gets me between an hour and a half and two hours. Playing SC2 gets me between and hour and an hour and a half. I was converting some videos using a multithreaded converter while synching and charging my iPod, listening to music, and running uTorrent while browsing with Firefox and I got 25 minutes.

Large gaming laptops are not really meant to use without plugging in. They are just meant to be more portable than desktops without really being all that portable.

Alienware M17x Core 2 Duo 2.4GHz 4GB DDR3 GTX 280 1GB 17" 1440x900 display

Brightness on full, wifi, bluetooth, etc. on ~2.5hrs. NFS: Most wanted ~2hrs Wolfenstein ~1.5hrs Normal usage ~3.5hrs

That might just be me, but my laptop's always got great battery. Much better than the Inspiron D630 junker I've also got.

Well I thought about that but I was just wondering about the gaming because there are frequent power outages here. I don't actually not want to not use all of my laptops functions and what would be the point of it being able to have battery life if I didn't use it? Besides, if I stuck this into the inverter that we use for the outages, how much life would the battery of the inverter have?? Don't know what you have to say about that but it is important that we at least have some lighting to do what we want to do. EDIT:@Daedulus: Which Wolfenstein are you talking about? New ones or the 1990s time period ones? Also how did you keep "great battery" life? Third, is NFS:MW really so simple that it doesn't bring the battery time down? I mean I have a friend with a Dell inspiron with integrated graphics, and the laptop is really worn out, but he still manages to get half an hour from NFS:MW.

My Macbook gets about 3.5 to 4 hours just doing basic things like web surfing and such. I can't say about the gaming life since i always have it plugged in when i play (mainly Left 4 Dead 2).

The runtime of an inverter depends completely and totally on the size of the battery connected to it so I couldn't say. My UPS (which is just an inverter, battery and integrated charger when you come down to it) runs my desktop PC and assorted peripherals for about an hour.

Personally, I'd put get another inverter for your laptop (a low amperage inverter isin't expensive in the UK, i've no idea about india) and connect it to a couple of car batteries in parallel. Assuming you know where to look, you can usually get those pretty cheaply as well because companies have to dispose to pay for them and as people don't usually dispose of a car because of the battery there tends to be a surplus of old car batteries around.

UPS's are usually run off a pair of 7 Ah batteries, giving you 14Ah. A reasonably modern car battery is 70Ah, a pair of which gives 140Ah and could be reasonably be expected to give me ~10 hours on my desktop PC, which is not exactly designed to be energy efficient.

Buy a spare battery and keep it charged. That will double the amount of playing time you get ;) Simple and effective.

I like the car battery idea. How would you go about doing it?

But if the power's out you still have to change the battery, which means shutting it down or hibernating it. Not exactly continuous.
