- I’m very happy with my Thinkpad P70, 4K 17” screen, 6TB of storage
- But it’s a bit power hungry.
- It tries to speed charge the battery at over 5A/20A, which is over 100W
- Trips airplane power outlets, and >100W on 12V usually ends up being over 10A, so it trips 12V car cigarette ligher adapters too
- Thinkpad center pin tells the laptop if the power supply is 45W, 90W, 135W or 170W using a resistor value.
- Hack my own adapter to select the power I can safely use
