This is the quote from the article:
"Turn off software (like the Hibernate or Stand-by mode in Windows XP) and turn off scheduled tasks."
I agree about turning off Stand-by and scheduled tasks but Hibernate seems safe unless I missed something about how it operates.
Thanks.

What does Hibernate mode have to do with it? I thought everything in memory saved to HDD and then powered off. Is something still running?
Standby mode is the power saving mode in which the monitor, HDD and some more devices are turned off but the contents in the memory of the computer are retained. This mode takes more power as the memory (RAM) needs to be maintained. In Hibernate mode, the system saves the present contents of the memory (RAM) to the HDD and powers off. This saves more power, but causes the system to take a longer time ( compared to Stand-by) to start-up. start-up.
Yes, that was my point. The original article indicated that hibernate was drawing power also which it is not from what I know.
I'm confused. I just got a new laptop from Dell, and they say to leave the power cord plugged in at all times unless you need to use the battery. They claim that a battery contains a finite number of charges/discharges, and once you use them up, the battery is dead. So they say NOT to discharge the battery often.
Basically you should get about 3 years out of a battery if you are using it every day.
If you NEVER discharge the battery, then DELL's advice about leaving it plugged in at all times is a fairly safe course of action. BUT once you embark on a course of using battery power, you enter the realms of 'charge memory'.
'Charge memory' is where the battery is depleted to a percentage of its capacity but not fully discharged. If you tend to run the battery down to the same point THEN charge it again, it tends to 'think' the partly discharged level is its fully discharged state. Over time this can have the effect of producing a battery that will suddenly go from partly discharged to fully knackered.
There are those that will contend this condition ONLY applies to NICAD (Nickel Cadmium) batteries. I don't agree, having witnessed the same symptoms with LION (Lithium Ion) and with NiMH (Nickel Metal Hydride) batteries.
Once a battery develops 'charge memory' the only sure (but not foolproof) way to get rid of it, is to fully discharge the battery. The best way to do this is to FULLY turn off power management and run the laptop on battery power until it collapses under the strain - a bit like HAL9000 (sorry HAL !!
) in 2001: A Space Odyssey.
