Hi. I have Dell XPS 15 9550 and Power Companion PW7015M. On PW7015M page i see it complitable with XPS 9550. But if i plug it in, BIOS show error on startup - "Alert! You have attached an undersized 45W power adapter to your system.......Use a Dell 130W (or greater)....."
Why BIOS display it? I see what i can disable it in BIOS setup, but it strange - complitable PowCom get this alert.
The Power Companion PW7015M/PW7015L is not a bootable power source. It is simply a battery charging device. It is compatible in the sense that it can charge the XPS 15-9550. I am not even sure if (1) will work. Test it.
* Laptop is off
* Wall outlet --> Laptop AC adapter --> PW7015M power in port --> PW7015M power out port --> PW7015M power output cable --> Laptop AC power in port
* Turn Laptop on
* Laptop is already on
* PW7015M power out port --> PW7015M power output cable --> Laptop AC power in port
* Charges Laptop battery
Ok, thanks. If use it only for charge laptop battery - it`s good. I thinked what i can plug it in, and work some more hours without poweroff.
