I just got my notebook this Friday and the battery wont go past 98%

Why? I thought it usually took a while before the batteries are losing charge but now it seems that my battery is already losing power.

 

Before you get your rack time:

1. Power down lappie
2. Charge battery

When you power on lappie, check battery %. If not 100%, call Dell.

Remember, charging while the lappie is powered on will always take longer than when its powered off.

 

l had left the battery charging with the notebook off for 2 hours and when l boot it up it said 98%. So l'm like ok...and 20 minutes later with the power adaptor plugged in it was still at 98%.

 

this happens sometime with my other laptop. try working on battery alone amd letting it discharge way down to low battery warning threshold level. that always fixes the problem for me. i don't know why, though...

 

Battery power isn't an exact science. Every battery is slightly different from the next one, and windows needs to figure out how much juice is in yours specifically. If you run it off the battery until it dies, then recharge it, it usually will figure out what 100% *should* be. It might take a few cycles before it figures it out.... but it will get it eventually. (for example, your battery might max out at 79.9Whr, but windows just assumed that it needs to be at 80Whr).

I experienced that with my old 630m, I took the advice of a forum member to discharge the battery fully the first time and then charge it all the way up with the laptop off... after I did that my battery read 100% when fully charged everytime i charged it...

 

scorpio, from what i've read its not a good thing to completely discharge a lithium ion battery then recharge it because while they don't have a memory they do have a limited amount of charge cycles.

 

Apparently you've read the same thing I have Per BatteryUniversity.com:

I'm sure one fill discharge wouldn't hurt, but I wouldn't do it.

 

True, but there's also another thing to consider. Lithium batteries are sensible to heat and they also drain naturally over time. Your battery probably "got hurt" since it was installed in Malaysia (or wherever) and shipped to you either by storage time, facility temperature, shipping conditions, etc. Also take into account that manufacturing procedures usually have a tolerance, I would expect it to be less than 1%.

I would suggest you download NHC as it tells you the wear rate of your battery, i.e. the capacity to what the battery can be charged as opposed to what it was designed to be charged with and check if it's up to par to what you're experiencing.

Another thing is that though full discharge does hurt your battery, neither Windows nor NHC can fully predict the wear rate of your battery, e.g. my laptop can't hold charge for much more than an hour with everything set to the lowest, but NHC reports 35% wear rate (it reported 31% yesterday) and Windows always say it charges to 100% (meaning it really "charges" to a 100% of the 65% left out to charge) and it's supposed to last for about 2:20.

 

let battery discharge completly then recharge it .
