Lyryx & HP

Tell me that you've had a successful experience with Lyryx testing. My son is taking his first test on Monday (maybe sooner) but I'm really concerned that he'll run into a computer problem on test day that I can't solve. Once the test is started, you can't go out of it and come back. So far I've learned how to go into tools to adjust the cookie and security options so he can get beyond the signin. Then I had to solve the "Several Java Virtual Machines running in the same proccess caused an error" problem by deleting and compressing and rearranging things to free up more memory." I'd feel better if my backup computers weren't the HP laptops that are under recall. Buying 2 laptops at the same time was one of my dumber moves. Having no experience with laptops, I just thought laptops were the stupidest things ever. Even having the list of problems, I don't know normal so figuring out abnormal is a challenge. I can't get them to do what I need but maybe it's a human error - I just know I lugged the big one to the school library and I didn't get web access. My fault or the computers? Wish I knew. Didn't realize I had a battery problem until I saw that youtube video - I just thought computer batteries died quickly. I'm definitely a desktop person. If I can sort out Lyryx and get the laptops working, I'll have to learn way more than I ever intended to about problemsolving.
