Few months ago it started just powering off whenever it was running on battery. Have tried several suggestions that I've seen on the forums with no luck. Recently even updated to Lion and tried resetting SMC again (is that the right acronym?). No luck. Any thoughts? Don't want to give up my baby but I'm tethered to the power cord so I might as well just use my desktop. Thanks! |

If it make a difference, the battery indicator shows full charge when it happens. How can I check the battery? |

- When a laptop battery is brand new...a 100% charge means 4-5 hours of battery runtime. - When a laptop battery is just about completely dead...a 100% charge can mean just 10 minutes of battery runtime (or less). So a 100% charged battery can mean VERY different things! At this point it's almost impossible to check this...since you computer shuts off as soon as you try to run it off the battery. So the only other way to check is...go to: - Apple Menu - About This Mac - click the "More Info" button - then select "Power" from the list on the left side of the window - on the right side of the window is the info we need Under "Charge information"...what does it say for: - Charge remaining (mAh) - Full charge capacity (mAh) Under "Health Information"...it should give a "cycle count"...what is this number for your computer's battery? - Nick - Computer slow, too many "beachballs", read this: Beachballs - Computer seems slower than it used to?

 It would seem that it's not the battery. Resetting the SMC would be the next thing to try...but you already did that. - Nick - Computer slow, too many "beachballs", read this: Beachballs - Computer seems slower than it used to?
