Question from Celina: I have a question about battery backup devices, Rick.

I went to our local office supply store to buy a battery backup for my iMac and the man I talked to said I needed to pay extra for one that provides “pure sine wave” AC current. The one he tried to sell me costs over $100 more than the one I had planned to buy.

He said the cheaper “modified sine wave” models can damage my iMac because it was designed to only accept only a pure sine wave signal. Is that true? [Read more…]

Question from Ethan: I was reading an article last night that discussed using part of a computer’s unused RAM as a RAM Disk, and it got me to thinking.

Question from Carl: I have 2 year old laptop that had Windows 10 on it before the hard drive died.

I bought a new Windows 11 desktop machine but I’d like to replace the bad hard drive in the old laptop and experiment with a different operating system.

I read your post about installing Linux in place of Windows but I’ve been reading a lot about Chromebooks lately. I stopped by Best Buy yesterday and tried one out, and I really like it.

My question is can I install ChromeOS on that laptop and use it as a Chromebook (after I replace the hard drive of course)?
