You're really cute lruggier

The old "charge and then let it drain and then recharge" scenario just doesn't work anymore and i'm not sure that it ever did.

^ I am very confused, can you just answer my original question with a simple answer--

Is it harmful to my laptop if I charge it up to 100% when it is just at 75% battery? Or should I wait for it to die until I charge it?

Since I have been charging it for the past month before it died I feel like the battery is having trouble holding charge more than 3 hours when it usually can hold up to 4-5 hours. Have I ruined my battery? All the power settings are on the same settings as before, which are the lowest ones.

Lithium Iion batteries like to be kept charged. They don't like to go below 10% and they REALLY don't like to be run down to Zero. So charging it when it's already at 75% doesn't hurt at all.

its not recomemded to fully charge when only at 75% but laptop/mobile phone device battery will lose there charge capaicty over time
so after a year you will find they dont provide the time stated when you got it new.

its not harmful to the laptop, its jsut harfull to the battery. if you need extra power during lessions
get your self a new battery thats been fully charged for stand by on the day you need it. a new battery will still lose some charge if its not
inuse so dont worry.

No, it isn't harmful at all. There could be some issues where the charge detection system isn't reporting an accurate % of charge, but charging a lithium ion battery from 75% to 100% should not harm the battery at all except that:
* The battery can only be charged a limited number of times (in-line with its "life" expectancy).
* You want to avoid charging the battery in a hot environment. So long as it isn't wrapped in a blanket or something, you shouldn't have this problem. But charging in a hot car, for instance, can really harm a battery.

Apple seems to say that it isn't full discharges that cause the trouble, but a deep discharge - for example, the result of a battery left fully discharged.

This is true about any lithium ion battery. The battery *shouldn't* drop below a particular charge or else its own internal circuit will be permanently damaged and incapable of holding any charge. For instance, if you have a digital camera that you rarely use and you forget to charge it last time so it is almost on empty and then put it away for a couple of months you will probably find that the battery is useless.

THANKS EVERYONE YOU GUYS ARE THE BEST

I called Toshiba explaining my problem and I convinced them to send me a new battery for FREE since I have an extended warranty for 2 more years. If this happens with the next battery I guess it really only does give you 4-5 hours for the 1st year, but as of now I am convinced that I messed it up by charging it while it had more than enough battery left (aka when it was at 50% or higher) just so I could get it to 100% and then take out the battery.

My battery used to last 3 hours and still have another hour or 2 left and now it barley lasts 3 so thats why I made this post in the first place because I have only had it for one year, how can the battery die at 3 hours already its still very new!

Well you have 2 batteries now, so if you are worried one will run out before you get home, take the other charged one with you

[lruggier]

Nope, I have to return the defective one so I won't be charged $142

Send them a melted lump of plastic and explain you can not understand how it lasted this long in that state

There is also the possibility that you just had a faulty battery... IDK, I myself have had mixed luck with lithium ion batteries. My iPhone 4 battery is almost 2 years old and it still holds a charge like it is new. However, I noticed a drop in battery life on my iPhone 3GS just after 9 months of use.

Ok, one last question for you all, when I get my new battery should I:

1.only charge it when it gets to 10-15%?

or

2. should I still charge it whenever I need to charge it up to 100% no matter how much battery I have left since its a Lithium-Ion battery and it will be ok if I do that and I can leave it plugged in at 100% if I want to because it does no harm to the battery since there is no such thing as over-charging a lithium-ion battery?
