OJAS Posted June 1, 2011 Share Posted June 1, 2011 According to the power meter on my Compaq Presario laptop, the battery now only charges up to 99% whereupon the battery indicator light starts flashing. This has been happening for a fortnight. Previously the battery charged to 100% whereupon the battery indicator light was extinguished. Does this mean that I should now replace the battery (which, with the laptop, is nearly 2 years old)? Link to comment Share on other sites More sharing options...
bangkockney Posted June 1, 2011 Share Posted June 1, 2011 It shows reduced battery performance. Still charging to 99% is OK. Mine currently only charges to 74% and I've been too lazy to replace it. When it is charged to 99% and you put your mouse over the battery icon in the taskbar, does it say something like: "99% available (plugged in, not charging) Consider replacing your battery." ? If you don't have the battery icon in your taskbar you can add it using Control Panel. Link to comment Share on other sites More sharing options...
astral Posted June 2, 2011 Share Posted June 2, 2011 Turn off the computer, remove the battery and reseat it. Possibly a dirty contact? How long with the computer run on battery alone? That is the best indicator of the state of the battery. I have had problems on a number of laptops with the internal charging circuit, and an expensive replacement battery did not help at all.
