Jim has an HP OfficeJet 6700 printer and he's having trouble printing in color now that he's upgraded to Yosemite. Leo says that HP probably has an updated driver for it. He should click on the drivers button at HP.com and it'll give him the drivers for his OS X version. He should just be sure he gets the driver that's compatible with OS X Yosemite. It's up to the manufacturers, especially with older hardware, to update the drivers and sometimes a software update will simply break connectivity.
Walter's sister had a Windows 7 laptop that hasn't been connected for a few years. When he connected it, the automatic updates didn't install. Leo says that she's so far behind, it'll take a half day to get all the updates, it'll probably have to be updated manually. Walter should check for updates and then install all the updates that pop up. He doesn't have to install the optional updates though, just the critical ones.
Jim has an iPad 1 and wants to know if he can still use it to run Sonos. Leo says that while the iPad isn't that old, Apple won't be updating it anymore. So he should update it as far as he can. But if he's not surfing around, and he's just using it to control the Sonos, he should be fine.
Richard turns off Wi-Fi when he's recording from his Android phone with TuneIn Pro. Now he can't turn the Wi-Fi back on. It does work in safe mode, though. Leo says that means an app is causing the problem. Could be a bad update. He should try resetting his phone. He should make sure his photos are backed up to Google Photos, and that he has his Google contacts backed up. Then go into pure recovery mode and wipe everything. He can also back them up to his computer via MTP. Once that's done, the issue should be fixed.
John upgraded his iPhone 4S to iOS 8.4 and now his email won't work. Leo says that the iPhone 4S is pretty long in the tooth these days, but since Apple is still offering it, they have to support it. This is why it's wise to be slow in upgrading older devices. But it should work since it installed.
Leo recommends backing up to iTunes completely, and then reset it. Others in the chatroom say they've had no issues with the iOS 8.4 update. So wiping the phone and starting over is a good way to fix the issues. Once John does that, he can restore his backup.
Diane updated her iPhone 5S to iOS 8 and now it's not running properly. She clicks on one app and another one opens. Leo says that there's always the potential of something going wrong when updating an operating system. It's like trying to pull a table cloth out from under dishes and trying to put another table cloth in its place.
Steve's Samsung Galaxy S4 and the recent update has taken out a messaging feature he relies on. Leo says that often happens in an update. But it may also be something he can fix in the default applications menu. If that's not going to fix it, then Steve's only other option is to root his phone and put a custom OS like Cyanogen mod on it.
Brent has an Acer Iconia tablet and it's starting to freeze up when watching movies. Leo says if you can update it to the latest version of Android, that would be a good idea. Another idea would be to go into backup/reset settings and restore it to the original settings. Sometimes that helps with issues by starting from scratch. Just make sure you have enough space. Clear out the cache.
Abdiel is having trouble updating his Nexus Player to Android 5.1. He gets a red triangle error. Leo says that over the air updates require more storage because it will need to expand and install the update. So he may need to restore the player before he can update it. If that doesn't work, it's possible that the OTA download is bad. Google has released the 5.1 image for download, so he should try that. Abdiel will also need something called "Fast Boot" on his machine.
Dan has been getting messages to update Java, but he's worried about security. Leo says that since Dan uses Windows XP, there is a security issue because Microsoft doesn't support it anymore. Google will update Chrome, so it's a good idea to use that as his browser. But he shouldn't use Java unless he needs to. If he does need to use it, he should make sure he installs all security patches. He should disable the browser plugin as well, and he should run Windows as a limited user -- not as Administrator.
