One of the best parts of restarting Langa.Com is hearing from readers. The collaborative “together, we’re smarter than any of us alone” nature of the old LangaList was one of the things I enjoyed most. I learned a ton from reader mail!
And once again, readers are chiming in via the Contact page and social media. That’s great!
For example, after reading “Why won’t my laptop charge when it’s running? It only charges when it’s off,” reader Olaf added to my initial answer with this:
“Another possibility is using a charger/power supply with insufficient Wattage to run the laptop AND charge the battery at the same time. For example many laptops will run on a 45W charger, but need a 60W or 90W charger to run the laptop and charge the battery at the same time.”
That’s true, Olaf. The PC circuitry will shut itself off to prevent damage in low-voltage/amperage situations. The PC looks dead, but it’s just underpowered.
Other readers responded to “A reader suggests caution re: laptop use.” For example, these two readers had similar ideas:
“Use a lap tray with your laptop?” — Simon Zerafa
“This is why I still have my EZ-LAP that Fred recommended way back when!” — DNFoster
You’re right, guys. A lap tray or any solid surface should allow the laptop to draw air normally from its underside vents; and a layer of something solid should also help keep your thighs — and other body parts! — cool.
Thanks for writing. Keep those comments, questions, and observations coming!

I have one of those really big heavy desktop replacement type of laptops, which aren’t really suitable for using on one’s lap. I stick a 17″ X 12″ enamel coated wire baking rack under it to elevate it off the table, giving it better airflow. (one of those wire racks used for cooling cookies and other baked goods) It was cheap, the perfect size, and I can use a loosely attached zip tie on the edge, to keep USB cords under control.
When I said cheap, I meant that I picked up a twin pack at my local supermarket for about $10 USD. One for me, and one for my daughter’s laptop. 🙂
She used to use empty tuna cans to elevate hers off the desk.
If I were to actually use a laptop on my lap, though, I’d probably invest in a large plastic cutting board and attach a wire rack on top of it, with duct tape. It might not be the prettiest thing, but it would give it better airflow than just a solid cutting board, alone.
The airflow is what’s important. The aesthetics really don’t matter. Whatever works! 🙂
