How come my Compaq Presario c700 laptop will not charge? 

by on November 26, 2010

Q: I have a Compaq Presario c700, and it recently stopped charging. My task bar says x% available, charging, but does not show the battery animation and the percentage never goes up (so it isn’t actually charging). I ordered a new battery today and both the battery and ac charger work fine in a different laptop. What could this be? Please help! Thank you!

How come the battery in my laptop said the battery had malfunctioned but now it says it is fine? 

by on September 8, 2010

Q: I have a Dell Inspiron 1521 laptop computer. There was a blinking orange battery light going off to the right of the keyboard. When I checked the battery meter setting, it said that the battery was plugged in but not charging. When I clicked the icon that says Battery Health, it said the battery has malfunctioned and needs to be replaced. I called Dell and ordered a new battery for a $172. An hour later, my battery shows that is 100% charged, and when I checked the Battery health, it says your battery is performing normally. The blinking orange battery light, however, is still lighting up. Can you give me any ideas about what is going on or what I could do? Also, can you suggest any websites where I could order a new battery for a better price? I have tried to cancel the Dell order, but it is after normal business hours, and even the website won’t allow me to do so. Any info you could give me would be greatly appreciated.
