Dim the screen. That's probably the biggest power  user.

What I have always been told is that the battery that comes with the laptops, are bottom of the line batteries.  You can get the model number from the battery and either go directly to fuji, or search online for a replacement battery. \n\nThey are expensive I know that, but the replacement batteries seem to be better quality. \n\nI know there are alot of batteries out there that dont mind if you recharge them even if they are not used, but a laptop battery stays longer if you completely use the battery, then recharge it.\n\nI think the longest battery life for a lap top that I have seen is like 4 1/2 hours.  I just can't imagine a battery lasting 11 hours, unless there was a dual battery.

I'm assuming you run your computer on for long amounts of time. The best thing to do is to get a cooling pad like mentioned and to slow down the processor so that it doesn't produce extra heat when not in use/under a large load. http://www.pbus-167.com/chc.htm Notebook hardware control is a great program you could look into to see temps and to slow the processor down when you don't need all 100%. It can also help save battery life when you're not plugged in.

Yes, of course.\nLaptops are made to be charged, and they charge fastest when shut down as they are not relying on power. I have to contradict what someone has said; I leave my laptop charging overnight all the time, and it has not done any damage to the battery.\nI hope what you do, is if you are using the laptop during the day you do not have it running on AC power, I'm pretty sure it is better to be running on battery.

sure, you get a 12 volt adapter for the laptop and run it off of solar power or a rechargeable 12 volt battery with a plug in - or an inverter for the regular plugin.

I would call dell tech support up and let them know the battery is a dud.  To keep the battery lasting longer fully charge it then let it drain 2 or 3 times right off the bat then fully change it and drain it once a week do not leave the power cord in the computer when you don't need it.  If you do this constently it will kill the battery.

Any inverter designed to run from a car battery which gives the current output you require should work. Connect the batteries in parallel for longer usage time. If you can get hold of a socket and battery connector from auto-parts supplier it would make connecting a single battery easy. Or did you mean you want to run your PC from your car anyway?

A few pointers for you:\n\n1. Make sure you laptop is not situated near direct sunlight\n2. Make sure that the room is well ventilated.\n3. Keep the laptop on a desk or table and do not obstruct any of the vents.\n4. Follow some quick tips to save CPU power and battery power\n         a. Lower LCD brightness\n         b. Close unnecessary programs and processes\n         c. Disable or disconnect any drives, USB devices\n             Bluetooth, wireless etc that are not in use\n\nBy saving CPU power and battery power, the temperature can be reasonably stable.  More work = More power = More energy = More Heat.\n\nThere are also clever dvices that sit under your laptop with built in fans to keep the laptop cool.  These can be purchased online.  Or you can easily make one up yourself.  All you need is a normal fan and the laptop slightly raised from the surface.  As if it had four little feet.  It has to be sturdy while you use it.  The fan help circulate air.

you said your laptop is 3 years old. if the battery is of the same age you're a lucky person. a battery seldom last that long when used daily (that's my personal experience).\nas already mentioned before, the battery is gone and you have to replace it.
