P670SE battery connector issue

Hello everybody!
I'm a little bit worried about the battery connector in my P670SE: when I open the machine to reset bios/nvram by unplugging the round battery under the keyboard, I usually disconnect the main battery too, and leave everything there for a few minutes. But when I reconnect the main battery, there's a little spark coming out within the white connector. Is this somehow normal? Could it damage the machine?
Also, when my battery is charging Windows 10 tells me how much time is left for a full charge, but if the battery is in use and therefore discharging, it is forever stuck on "Calculating...": faulty battery or Windows 10 bug?

 

When you say there is a sparkle, are you saying that it is like a constant spark, or do you just see it when you connected the battery in? Or could it possibly be just a little light reflecting off of a metal connector in there?

Did the battery level ever update to show a percent? Maybe clearing the EC might help with the battery issue?

 

Sorry, did a typo up there, I meant spark. It happens only when the battery is disconnected for a few minutes: when I reconnect it, within the white connector there's a very quick electrical spark. It worries me because it never happened to me with other laptops, though those had the usual removable batteries while this has an internal one.

Already tried clearing the EC: disconnected main and bios battery, then pressed the power button for ~20 seconds (is that correct?). But nothing changed.
Yes Windows 10 shows the percentage correctly. But remaining time is always "Calculating..." during discharge. While charging it's fine and shows remaining time for a full charge. Am I the only one with a P6xxSE and Windows 10 combo having this issue?

 

If it is just a quick spark, it should be fine as it is just the connection being made. If it was sparking constantly, then it is a completely different issue.

Yeah, that is how you would want to clear your EC.

Have you tried just running the computer from 100% down to almost dead? It could just be still calculating and running it from full life to almost empty could help with that process. Try changing power modes in the control panel for advance power settings, to see if it comes up in battery saver mode as well as the full power mode.

 

You should be fine. It's not uncommon for minor electrical arcs to show when connecting power. Take a look at the connector on the board as well on the battery just to make sure you don't notice anything odd (something caught in either one, a bent pin, etc.).

 

Thanks pat, already tried those but still no time shown during discharge. Next monday I have to ship the notebook to my reseller (Santech here in Italy) due to a cosmetic part detaching by itself (guess the glue got loose on the front speakers cover) so I asked if they could take a look at the battery as well! Hope they'll find a fix! Thanks for your help!

Ok thanks, feel a lot less worried right now I'm going to check the connectors tomorrow!
