What is what to do when chromebook won't turn on?

Here's what to do when your Chromebook won't turn on:

First, try a simple hard reset. Hold down the Refresh key (usually a circular arrow) and the Power button simultaneously for several seconds. If the Chromebook starts, great! If not, move on.

Next, check the power adapter and charging cable. Ensure they're properly connected to both the Chromebook and the power outlet. Try a different outlet to rule out a faulty power source.

Let it charge for at least 30 minutes, even if you don't see a charging indicator light. Sometimes the battery is so depleted that it needs a significant charge before it can power on.

If it still doesn't turn on, try a battery health check (if your Chromebook model supports it). You may need to press and hold a specific key combination while powering on, consult your Chromebook's manual for specifics.

If none of these steps work, there may be a hardware issue. Contact the manufacturer's support or a qualified repair technician for further assistance. The motherboard may need to be checked or replaced.
