Discussion Overview

The discussion revolves around the use of a laptop with a failing battery, specifically addressing concerns about potential harm to the laptop when operating primarily on AC power without a functional battery. Participants share personal experiences and advice regarding battery maintenance and lifespan.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses concern about using a laptop with a failing battery and seeks advice on whether it could harm the device.
  • Another participant reassures that using the laptop plugged in without a functioning battery does not harm the computer, noting that batteries have a limited number of charge cycles.
  • A participant shares their experience of a similar situation, suggesting that removing the battery while using the laptop plugged in can extend the battery's lifespan.
  • There is a mention of the heat generated by the laptop potentially reducing battery lifespan, with one participant affirming this point.

Areas of Agreement / Disagreement

Participants generally agree that using the laptop on AC power without a functioning battery does not harm the device. However, there are differing opinions on the best practices for battery maintenance and the effects of heat on battery lifespan.

Contextual Notes

Some assumptions about battery behavior and lifespan are present, but specific conditions under which these claims hold true are not fully explored. The discussion does not resolve the best course of action for battery maintenance.

Who May Find This Useful

Individuals experiencing issues with laptop batteries, those considering the implications of using laptops primarily on AC power, and users seeking advice on battery maintenance practices.

Hi alls
Just last week, my laptop Dell C400's battery was down. The battery led blinks all the time. I do not want to buy a new one right now, may be after several months, I will buy a new laptop because this one is rather old (3 years or so).
Of course I can use the pc with its adapter on all the time (or out only 10min). But I don't know if I use the computer like that, there may be something doing harm to the laptop itself? Can anyone who's got experience on this please explain to me.

Thanks

You're not harming the computer in any way. The battery's just not able to hold a charge anymore. They're only good for several hundred charge cycles.

Thanks Chroot.
Anyway, I ve been using like this for more than 1 week, with the bat LED blinking all the time. May be I have to blindfold the LED.

Does the blinking bother you that much?

Just a litle bit. The LED then turns out to be orange, not green as it used to be. It seems like 'SOS' signal.
 
I have a Dell Latitude, and after less than a year of using it (plugged in most of the time), the batteries no longer work. So just an additional note that if you use your laptop with the adapter most of the time, just remove the batteries completely. It will extend their lifetime by a good while.

(Oh, but fortunately my story ends with Dell replacing them (on-site) for me under their warranty - not that they paid me to write this post or anything =P)
 
mezarashi,

You're correct. The heat generated by the laptop does indeed reduce the battery's lifespan.
