Ok, I was wrong, but I strongly suggest diagnosing the power adapter. Check for voltage with a multi-meter, realizing that it might not be easy while traveling.

I have to admit that I only checked with Bic and Labi for the HP adapter, because they were walking distance, before I ordered online. I have quite a number of Lenovo adapters so would never need to buy one. I am also guessing that Lenovo has a lot more laptop sales in Japan than HP -- with good reason!

My Juice died long before I went to Japan. I suppose Japan would have the device operate at the highest input currents within its range.
