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
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.
