Hi Community,
I’m trying to power my 13th Gen Intel Framework laptop using a power supply and a USB4 docking station (60W output).
Here’s the situation: When I put a heavy load on the laptop, it seems to draw more power than usual. Besides the dock, I’m also using a power supply capable of providing 100W at 20V (5A). When the laptop is under heavy load, it disconnects from the dock and reconnects every within15 seconds or so and it works for a short time like 30min too the next heavy workload peak
I always connect the power supply first and then the dock, so the laptop initially draws current from the power supply. However, it seems that when under load, the laptop tries to draw power from the dock, which doesn’t make sense to me. I have a USB-C multimeter, and I can see that the laptop peaks at 92W from the power supply, but I can’t measure the power drawn from the docking station because my multimeter only supports power transfer.
To solve this, I bought a new, more powerful power supply, hoping it would work. But now there’s a new issue.
The laptop charges while it’s shut down or closed, even in the BIOS (I’ve set the battery limit to 100%). However, as soon as I boot into Windows or Linux, the charging LED on the laptop blinks on and off, and the battery icon in the OS does the same.
After an EC reset and booting into the OS, it works for a short time, but as soon as the laptop demands more power, either the power supply or the laptop breaks the connection, and the LED starts blinking again.
Does anyone have any ideas on what else I can try? Or should I go for the official 180W Framework power supply, even though it costs twice as much as my current HKY adapter?
And yes i checked my cables, they are th4 and rated for 100w.
My 140w power supply have a not deatachable cable
