Dell c640 battery problem

\015 Hello,\015\012I have a dell c640. Just replaced battery and when I have it plugged\015\012into the laptop, and plug charging cord in, the charging indicator\015\012flashes orange twice rapidly then green. it cycles like this until I\015\012unplug it. then when I return the plug it is a solid green. What does\015\012this mean? Also, it does not charge when the laptop is powered down. The laptop only appears to be charging when it is powered up.\015

Answers :

This sounds like it is not getting enough amperage from the power brick- check which model power brick you have. I'm not 100% sure but the pa-6 family may not provide enough power to charge and run the laptop at the same time. the PA-9 should- if it's rated at 4.51 @20v - that works out to about 90watt. If you DO have a 90 watt power adapter and it's still giving the orange then red flashes- and will not charge when the laptop is off- you probably have either a bad battery, or the motherboard is faulty and has a bad charge circuit, or a loose power jack. What does pressing the little button next to the charge indicator on the battery do? Flashing every other led- 1,3,5 is BAD, so is 1 and 5. You also might have a 3rd party refurb- that had the guts torn out and is not properly "seen" by the laptop.
