Laptop or desktop computers and any components within.
Dan is on his computer for about an hour and a half in the morning, then another hour and a half in the evening. Dan is wondering if he should shut down his computer during the day, or leave it on and have it go into sleep mode. Leo says that modern computers handle power pretty well. He can choose in his power saving control panel a variety of different schemes, but the default should be fine. It will go into a low power mode that only uses a few watts, even less than what a light bulb would use. During the day, if he's going to use it off and on, that's what he should do.
Ooma needs a new computer and she's heard that Quickbooks and Excel doesn't work well on Mac. Leo says that there is a Mac version of Excel, and there is an online version of Quickbooks, but it's better to use in Windows.
Will Windows 7 be supported for awhile? Leo says yes. Microsoft will support it until at least 2020 for extended support, but Microsoft will end mainstream support in January 2015. Security wise, they will support it through 2020. Leo also says this is why Microsoft is pushing Windows 8 hard. Windows 9 is next year, too. But Ooma has until 2020 to change OS.
James just bought a 3TB hard drive, But Windows XP only sees less than a TB. Leo says that's not surprising. The bios of the computer may not see all the hard drive, but the OS is so old that it may not see it all either. For 3TB, he would need GUID. He can partition the drive into smaller chunks, though. He'll need a disk manager to do it. The XP Disk Manager should be able to handle it.
Sean has heard that SSDs lose sectors over time. Leo says all hard drives do that. SSDs, though, use wear leveling to make sure that all sectors wear out equally. That's why he uses all SSDs in his computers -- they're very robust. SSDs are now getting cheaper in price, too, making it affordable to use for everyone.
Elliot has discovered he may have malware on his computer. When he hovers his mouse over an item in his browser, he loses control of his mouse. Leo says that it's likely an issue with Elliot's wireless mouse and chances are, he needs to change the batteries or reinstall the drivers. This is why Leo only uses wired mouses. Get a wired mouse, they're cheap.
Steve has a car stereo and he wants to connect it to home speakers. Leo says that he's got the resistance mismatched which could cause some damage. Steve will need a step converter to be able to handle it. But many believe that there's not enough mismatch to worry about it. An impedance matching transformer would fix it, as would two speakers in parallel.
Jeff is looking to get a MacBook Pro for college and he's wondering if there's a difference between the dual core and quad core processors. Leo says that quad core is more about speeding up rendering times than anything else. The higher end 15" model uses an NVidia Iris Pro GPU, which would be a more noticeable difference from the lower end models.
Jonathan has a laptop running Windows 7 and wants to double his RAM to 4GB. Leo says that's a good idea but he wouldn't go beyond that if he's running 32 bit. Online sources include Crucial.com, TigerDirect, MicroCenter, there's plenty of others. But Crucial will help him pick the right memory for his specific computer and has tools to help him install it.
Bob has a MacBook Pro from 2011 and wants to know if there's a new model coming out. Leo says that 2011 MacBook Pros were subject to a recall, so Bob should check that out first.
Should he upgrade his computer with an SSD? Leo says that's a good idea and he advises getting the Mercury SSD from MacSales.com. They're 1 to 1 compatible with the Mac. He should make sure his SATA Bus is fast enough, though.
If you are running out of power on your iPhone or iPad, the UNU Ultrapak can bring it back up to speed in less than 15 minutes, with up to 75% power. The Ultrapak charges itself faster too, being able to collect energy at record speeds –up to 8X faster than conventional recharging methods. To achieve such charging speeds, Ultra-X deploys a much stronger charging input, rated at 31.25W. This means that within approximately 15 minutes the Ultrapak has stored the equivalent of a full iPhone 5 battery.
