I definitely agree with #2, not just for laptop power but also for all your electronics. Surge protectors are very inexpensive and sometimes offer equipment protection guarantees if you register your surge protector. I have lost many electronics because the power adapter had a short and fried the equipment. Every time you vacuum or every time your refrigerator motor turns on it causes spikes in power demand, and a surge protector is definitely something your should have connected at all times.

2. If you use laptop most of the time at home or a place where there is a continuous (= uninterrupted) power supply, then simply remove battery from laptop and run laptop on AC power. If you are doubtful about current surge in AC supply, use a surge protector or a UPS (uninterrupted power supply) unit, which doesn't cost much.
3. If you use AC power most of the time, then store battery with 90 to 100% charged condition in a dry, away from any magnetism. At least once in a week or two weeks, run the laptop on only battery supply, let discharge it to about 10%, connect to AC supply, charge battery to 100%. Shut down, disconnect supply, remove battery from laptop and then use AC power supply as usual again.
7. Whatever you try, a battery has a specific life time (no. of charging/discharging cycles), and it discharges slightly/continuously over a long period even when not in use. So if your battery is giving problems after about 3 to 5 years of service, then it is time for its replacement. Don't assume that if you don't use battery more often, it will last longer, it may usually, but battery failures are unpredictable.

Here is my contribution to this valuable post :
Point 5 : in addition to the screensaver blank option, you may also create a special "theme" with dark colors (black desktop, see tab 2, and color model with dark backgrounds, see tab 4). When you need more battery autonomy, all you have to do is to activate the theme, because the dark colors will use up less battery energy. Please correct me if I'm wrong.
Point 6 : I would desactivate all those devices you never use or don't use much oftem, such as the 56K data-fax modem, the plug & play screen, the PCMCIA (unless you use it), the Ethernet card (if you work with wifi), etc ..
I only have ONE QUESTION remaining, about Point 2 :
Let's assume the surge in AC supply is 100% reliable. Is it a good idea FOR THE BATTERY LIFE to remove it when you work with AC supply ?? There was no conclusion on this debate between your post and the comments.
