jones333333 Posted December 8, 2017 Author Share Posted December 8, 2017 Jake Lo, I tried everything but without any success. I also tried to replace the battery by a new one again and it doesn’t seem to make a difference. Battery is draining 1% per minute it seems... I checked my processor speedstepping and it seems to be working correctly too. Anyone encountering the same issue with this model ? Link to comment Share on other sites More sharing options...
black.dragon74 Posted December 8, 2017 Share Posted December 8, 2017 Check activity monitor's energy tab and see if you find something that's draining all the juice. Link to comment Share on other sites More sharing options...
jwresp Posted January 13, 2018 Share Posted January 13, 2018 Re: wireless card, if ther E7440 has space for a full size card, I highly recommend this: https://osxlatitude.com/index.php?/topic/7554-apple-broadcom-bcm4360cd-80211-ac-wifi-and-bluetooth-combo-card/ Just for anyone interested in doing this: I managed to fit a BCM94360CS2 with PCI-E adapter in the WWAN slot of the e7440. I had to replace the original antenna's (which I think had U.FL connectors) by 2 MHF4 antenna's to get it working. Works perfectly out of the box , be sure to enable WWAN + Bluetooth in the bios though. 1 Link to comment Share on other sites More sharing options...
Schiller Posted March 7, 2018 Share Posted March 7, 2018 Off-topic but I also achieved this, I didn't replace the antennas since I was lazy to open the LCD panel, instead I soldered (only a drop above each connection so they stay in place) the E7440's built-in antennas to the BCM94360CS2 chip connectors. Everything works as intended "out of the box" (no WIFI or BT patches at all) handoff, continuity, hotspot, etc. 2 Link to comment Share on other sites More sharing options...
