    Note from just sleeping my battery just drained from 68% to 24% since my last post.

    bellaluna: Your machine obviously was not asleep during that hour and a quarter. Something is almost certainly running on it, unbeknownst to you, that is using a lot of CPU/GPU cycles and preventing sleep, thus draining the battery and perhaps generating a good deal of heat. If that's true, you can probably discover what it is by following the steps in this article:

    Thanks EWW, had a antivirus updater program that was running at 90%. When my computer gets charged up again all open up ppt and see how long I can last on battery.

    I have had macs since 1988 and never, ever ran a anti-virus program and never had a virus. The windoze world is filled with virii, but the mac world?

    I know macs are not highly targeted but since their gain in popularity I like to err on the side of caution.  Plus I need to know that client info is safe, and since I work with those who have PCs I don't take chances on other's files.  Perhaps unneeded (I really don't know).

    I really think it is a waste of time and processor. Macs are very secure.

    The only antivirus software recommended by the most experienced participants in these forums is ClamXav. Unlike ALL of the commercial AV products, it won't ever cripple your Mac by slowing it to a crawl, and despite being free, it's updated as often as any: i.e., a day too late to prevent the first infections by newly released malware. Those who are foolish enough to invite trojans into their Macs by downloading from untrustworthy websites will always become the victims of new trojans before ANY antivirus software has been updated to detect them. There are no viruses at all that can infect OS X; all known Mac malware takes the form of trojans that require the admin user's permission and password to be installed. If you use your head and don't invite disaster, you're practically invulnerable to any malware that can affect the Mac OS.


    Anyone who runs Windows on any computer without up-to-date AV protection is utterly foolhardy, and has earned whatever trouble s/he gets into with Windows-based malware of all kinds. But even with the most up-to-date AV software, ordinary users on any platform are always a day or two behind malware writers. The particular advantage of the Mac OS over Windows is that no one has been able to infect it with anything without the user's assistance/permission, while there are many thousands of malware exploits that can trash Windows computers without any help from the admin user.


    So protect yourself against Mac malware by using your head instead of depending on AV sotware that's always a day too late to protect you, and leave it to your Windows-user clients to protect themselves and each other, because you can't do it for them no matter what AV software you install.

    So far since removing that process from AV software my batter has lasted 3:48... and still has 38% left.  I have my screen at 90%, safari is open, word, open and ppt is looping a large 250 slide show.  I have my stopwatch going to see how long it takes to get to 1-2% It has been running since 11:30.  Perhaps I found my solution.  My next test is tommorrow when I'll actually just be using my computer to work with ppt, word, and light internet usage, and maybe makeing some flash cards with mental case for medical school.  This will be the real test to see if the battery is good enough for me in the manner that I use my computer.  I'll repost when I have details of how long my battery lasted.

    Thanks again.

    Just read your reply.  I agree wholeheartly.  My 05 iBookG4 was everything I ever needed.  The original battery lasted 5 years before it needed a replacement.  That one lasted one year.  Went back to Apple this past Aug. and was told they no longer make a battery for this model and told me I had a "dinosaur".  What?!  No longer make a battery for it!


    Purchased same model as you MBP13" three weeks ago.  Battery runs down under one week with same usage.   Directions say to calibrate at least once a month, I do it once a week since it drains to zero that often.


    I should never have bought it before the holidays, got busy, and now I'm out of the return time.  Guess I'll go back and have them check this battery.  But, I'm really aggravated to have this problem. 


    Good luck with your studies!

    Came across your posting when seeking info on battery life. Are you still in Italy? Would be interested in knowing where your Apple Store is.

    Does 187 refer to your telephone exchange as we live in the 187 area.
