Dickie D is back with the Anker Astro Pro (2nd Generation) backup battery. This is a 15000mAh battery pack, which holds enough power to charge smartphones 4 to 7 times and tablets 1 to 2 times before it needs to be recharged itself. The Astro Pro identifies what device you want charged and enables the best charging configuration for it thanks to a built-in chip. You can charge up to three devices at the same time.
Mike's old PC died and he needs to replace it. His budget is $500. Amazon sells refurbished computers, so he's wondering if that's a good idea. What's the difference between refurbished and like new?
Diane wants to get a larger battery for her Asus 11" laptop. Leo says that she can't get a larger internal battery because they're usually proprietary. One solution is to get an external battery that can plug into the laptop and charge it. She'll just have to have to get the right tip to connect to her battery.
Jeff just installed an SSD into his Lenovo desktop, but he can't enable AHCI (Advanced Host Controller Interface). Leo says it's in the kernel, but it doesn't mean it has to be enabled. Leo suggests using native mode since Jeff only has one drive anyway. He'll get the best performance he can for SATA 2, but he'll still have a speed improvement over the old hard drive.
Denise just installed OS X Mavericks on her Mac Mini and she's getting an error message about not having a microphone. Leo says that's a feature in Mavericks because laptops have mics built in. She can just get a third party microphone with a minijack so she can talk to Siri on her Mac Mini. MonoPrice is a good place to get them.
Chris is still having issues with OS X Mavericks and wonders if upgrading to 8GB of RAM would help it's performance. Leo says not really unless he's doing video or photo editing. If the Mac is running slow, it won't hurt to double the RAM. 8GB is a bit of a sweet spot, though, and it could help if he's having performance issues with the OS. But the real issue could be Mavericks itself. It's filled with bugs and Apple needs to fix it. The chatroom also says to go into the activity monitor and view his RAM usage. That could show him where the issue really lies.
The Giz Wiz is back and this week he brings along the PowerPot, a camping stove pot that you boil water in and will charge your smart phone at the same time! It contains a lightweight thermoelectric generator that converts heat into DC electrical power. The company says their 5 volt PowerPot will charge cell phones, GPS units, iPods, and lithium ion batteries, or will run speakers, lights, fans, and other low-power USB appliances. It comes with 3 feet of heat resistant cable. $149.00
Chris recently discovered that his ISP is charging him for his broadband modem. Can he buy his own? Leo says sure! He should contact the cable company and find out what modems they will allow and then buy that. Arris is a popular one and he'll want it to be DOCSIS 3.
Steve is having trouble with his screen refreshing a lot on his PC after having changed motherboards. Leo says that swapping out a motherboard is a huge change and it means he needs to do a clean reinstall of Windows after formatting the hard drive. Since Steve is using an OEM copy of Windows, it's trying to install the wrong video drivers. Steve should delete all the drivers from the device manager and reboot.
