Battery Power on MacBook Pro or Dell Inspiron 6400

by mike_quesnel / April 7, 2006 2:19 PM PDT

Does anyone know how long the average battery lasts on average usage of the 1.8 or 2.0 MacBook Pro? Average usage would probably be like surfing the web and writing papers and watching online videos and maybe chat a bit, stuff like that, not like hardcore video and photo editing. Also i was looking into the Dell Inspiron 6400 and was wondering if it was any good?

I expecting to receive my Inspiron 6400 that I ordered any day now (no later than Tuesday).

But I think the Inspiron 6400 is a very powerful laptop with good pricing.

Once I check it out, I'll post again to let you know.

It lasts about 500 to 1000 charges or about 1.5 to 2 years.

The battery technology and the life of the battery is fairly consistent from laptop maker to maker. The dirty little secret is that with use (not so much if it just sits there on AC power) that over 2 years the number of minutes you get on a full charge changes as it ages. It is not a straight line of say 3 hours when new to 15 minutes in 3 years but can be a curve or other trajectory.

They don't tell you this in the showroom and none have produced a chart about battery "life." If you do use battery power a lot, be prepared to replace the battery after year 2 so you get back to the hours of runtime when new.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
