Dell Venue 11 pro blinking led after battery replacement

Hello. Recently got refurbished Dell Venue Pro 7140 from ebay, after several months of light usage, power led started to blink red 4 times followed by 1 white. Eventually battery stopped charging, and tablet worked only with dock or ac cable attached. So i replaced battery with a new one. But power led still blinks when tablet is on battery. Except that - everything seems to be ok. Battery is charging and discharging normally, tablet is working fine and passes all the internal tests. Both AIDA64 and bios show battery health as excellent.

So, is there any way to maybe reset battery stats? Or somehow deal with annoying led?
