I'm going to be going to Japan soon, and am going to be bringing my old laptop (Pentium 233) to watch stuff during the flight. I've got two batteries for the thing, but they only provide about an hour runtime each. One thing I've heard is that sometimes, depending on your flight class, you don't get DC jacks to power your portables. So, what I was thinking is to take a UPS in my carryon to power the laptop.
I have a few questions though. This laptop doesn't draw much power, and probably takes less than 60W at max. They normally rate the UPS system run times in terms of a desktop computer and a 15" CRT. I would get a considerably longer runtime with my laptop then, right? Wouldn't it be far more worth it to run off a UPC with a much bigger battery than the laptop in a backpack?
Also, I've heard that UPS systems make noise and would disturb other people. However, I thought that UPS systems only beep when they are overloaded? Do they make any other noise that I should be aware about?
Thanks for any replies, and please don't respond back with something like, "Go out and buy another REAL laptop battery." I'd appreciate it!
