devilunder Posted March 29, 2020 Share Posted March 29, 2020 Hello @trognaz, thanks a lot for your E7440 guide!!! I have installed it successful on my Dell E7440 with Intel i7-4600U, 8GB DDR3 1600 MHz, 256GB mSATA SSD on A28 BIOS. My Battery is fine but it is drowning capacity very fast, did yours too? regards Devilunder Link to comment Share on other sites More sharing options...
morpheousman Posted March 30, 2020 Share Posted March 30, 2020 How long is it lasting? I have seen no difference since upgrading to 10.15.4. My battery lasts about 90 minutes on my i7 core. The battery is several years old. 1 Link to comment Share on other sites More sharing options...
