mak123 Posted May 23, 2010 Share Posted May 23, 2010 How many years you are using that lap? my laptop also same trouble. your battery life is coming down. it may come down to 15 mins backup time. you need to replace with the new battery. Link to comment Share on other sites More sharing options...
Cosmin Posted May 23, 2010 Author Share Posted May 23, 2010 2 years or so .. any link with compatible battery & reasonable price ? Thanks . Link to comment Share on other sites More sharing options...
Kenji Posted May 23, 2010 Share Posted May 23, 2010 Maybe if you actually gave some info on what laptop you have, you would receive a link in return. Link to comment Share on other sites More sharing options...
Billus Posted May 23, 2010 Share Posted May 23, 2010 If you load up a live Linux disc, you can check the stats of your battery such as its capacity and charge rating. Great for troubleshooting as the battery may be ok, just that there is a process running in Windows killing it in 30 mins.... :unsure: Link to comment Share on other sites More sharing options...
+jamesyfx Subscriber² Posted May 23, 2010 Subscriber² Share Posted May 23, 2010 What's the make and model of your laptop? My mother has an HP 620s and the battery now discharges in about 3 minutes or so. Even in Linux - which is now it's primary OS. Link to comment Share on other sites More sharing options...

kead Posted May 23, 2010 Share Posted May 23, 2010 Chances are your battery capacity is gone. I'm going to take a guess and say u keep the battery in the laptop while always on AC power. The thing is with Li-On batteries, the cell structure gets weakened when u keep them at full charge for long periods of time. They recommend storing Li-On batteries at around 50% charge to reduce capacity decreases over time. You basically need a new battery. Link to comment Share on other sites More sharing options...
Guest xiphi Posted May 23, 2010 Share Posted May 23, 2010 Run "powercfg -energy" in an Admin Command Prompt and paste the results. Link to comment Share on other sites More sharing options...

Guest xiphi Posted May 24, 2010 Share Posted May 24, 2010 Looks like your battery is fine. You might want to adjust some of your settings in the advanced power options. Especially graphics card settings, as those will drain your power faster than anything else. Link to comment Share on other sites More sharing options...

kernelhacker Posted July 25, 2011 Share Posted July 25, 2011 Looks like your battery is fine. You might want to adjust some of your settings in the advanced power options. Especially graphics card settings, as those will drain your power faster than anything else. I know this thread is dead, but wanted to clarify something in case someone (as I just did) finds this when searching. Actually, the battery is dead. You'll need to replace it. :( Xiphi is absolutely correct in asking for "powercfg /energy" and his analysis of the same is also correct - assuming that the results provided were actually true! On some older systems (including this one), the BIOS will lie and report the "Current Capacity" as the "Design Capacity". :wacko: Whether you attribute this to malice (hiding the fact so they don't have to pay for the battery during the warranty) or incompetence (Older versions of Windows didn't report this data point) is up to you. The fact that the two numbers are exactly identical is a tell-tale sign. Maybe, just possibly, if you checked right when you first bought the computer you would get identical numbers. Also, I think that the battery capacity numbers are low to the point that they are missing a digit. :) Link to comment Share on other sites More sharing options...
still1 Posted July 25, 2011 Share Posted July 25, 2011 What's the make and model of your laptop? My mother has an HP 620s and the battery now discharges in about 3 minutes or so. Even in Linux - which is now it's primary OS. I am thinking Linux is the reason for the battery drain. I have had two instance where the battery have drained to less than thirty min after using Linux for few weeks. Last year my battery drained low(After i installed Linux side with Windows) and had to call Dell and they replaced it for free. It has been fine for more than year and then a month ago i installed Linux and now windows 7 shows warning and asks me to consider replacing the battery. Now my battery is somewhere in 40 min range and i have stopped using Linux. A month ago my battery was giving me a solid 1.5 hours..... Link to comment Share on other sites More sharing options...
