Chosen Solution

I got a hold of a couple of Dell Chromebook 11 without the AC power adapter and I was wondering if there’s a way to power them on without the power cord?

Hi @nevenlearn5150 , Given the cost of the charger it may be easier to simply purchase a compatible one than trying to connect a suitable power supply to the laptop i.e. voltage supply with a regulated, constant 19.5V DC voltage, with at least a 3.34A output with the appropriate DC barrel type plug connector. Easiest way to damage the motherboard is to connect a power supply that is not exactly what the motherboard was designed for. If I haven’t linked the exact one, search online for Dell Chromebook (insert model number) charger to get results for suppliers and prices that suit you best

That laptop uses the 19.5V wide barrel tip, which is super easy to find and can be purchased anywhere laptops are sold, especially Dells. The thin one can be a challenge, but not the wide tip because of how many laptops use it. Your Chromebook uses the same tip as my Lat 7490.

As long as it meets or exceeds the factory wattage (likely 65W, but could be 45W) it’ll work. I could let you use my 130W adapter as long as our tip voltages are the same (19.5V) despite the fact it’s a total waste. The adapter only draws what it needs so if you only need 65W max on a 130W adapter, you’re leaving 65W of max capacity on the table. Yes, sometimes mine is a waste too (like on mid spec Lats with the i5 and can run on 90W comfortably) but on the other hand say I power a i7-8650U 7490 - that headroom is potentially useful. Even the 8th gen-present 4C/4T or 4C/8T U series CPUs are not power sippers once you step into the world of i7 but aren’t power hogs like the old 47W MQ Haswells - they never made it into the E6440 for a reason. Check this label on the back of the Chromebook to be sure:

Dell offers all replacements via the phone. I would call them, explain the problem, and go from there. Hope this helps!
