You can get used 8440p laptops pretty cheaply because HP Elitebook 8440p overheating is rather common. Symptoms of overheating include unexpected reboots, shutting down, and bluescreens.
The problems with the cooling system are unfortunate. They have nice keyboards, they’re easy to work on, and they’re reliable otherwise, so they’d be nice laptops if they didn’t overheat so much. Here’s how to improve their cooling so you can get a bargain–buying off-lease business laptops is a great way to save money.
Disassembling a Marx 490 locomotive isn’t too difficult, but it’s very different from other Marx locomotives.
Once you take one apart, though, you’ll see why it was designed how it was. It was Marx’s lowest-cost locomotive, and it could be assembled without tools, so the labor costs were minimal.
For that matter you only need one tool to take it apart, and since there’s so little in it that can break–not even a headlight–you can find anything you would need to service it at the nearest hardware store or auto parts store.
Windows 10 is out today. Of course I’ve been getting questions about whether to upgrade from Windows 7 to 10, and I’ve been seeing mixed advice on upgrading, though some of that mixed advice is regarding Microsoft history that isn’t completely relevant today.
My advice is to upgrade immediately if you’re running Windows 8 or 8.1, and to wait, perhaps six months, if you’re running Windows 7, but I still think you should do it. I’ll explain.
I was on a conference call discussing the Microsoft product lifecycle with several coworkers and our Microsoft-assigned support engineers when someone asked if a server version of Windows 10 was going to come out.
The Microsoft rep said no comment. Then I chimed in.
“We need to assume they will release a server version, probably about six months after the desktop version, and we need to start testing and preparing to deploy it when it comes out,” I said.
I went looking for a reliable, modern controller to use on my Retropie setup. I eventually settled on a Logitech F310, betting the Logitech F310 on Retropie would make a nice combination based on my experience with other Logitech peripherals in regards to their quality and value for the money.
The reviews I found suggested the F310 continued in this tradition, and I found enough people who said they got it working with Linux to feel confident I could get it working on the Raspberry Pi. And sure enough, I did.
I paid $18 for mine, and my first impressions of the quality were good. It’s precise, and button pushes register with a slight click. It’s no worse than a Sony, Microsoft or Nintendo controller, and if anything, I think I liked it a little better. A pair of Logitech F310s costs more than the Raspberry Pi board, but playing games is a lot more enjoyable when the controller does what you want it to do all the time, not just most of the time.
The F310 wasn’t a drop-in replacement for the controller I’d been using, though. I had to configure it for Retroarch, the software that provides most of Retropie’s console emulation.
After rooting a device and loading a ROM or two on it, it’s easy to start to wonder what tweaks and settings actually make a difference in performance or whether you’re just imagining things. For example, my devices all have the option to force Android to use the GPU for rendering (under Developer Options), but does it really help?
Benchmarks are a synthetic but objective way to measure the effect. I use Antutu. Read more
My Nook Color is my experimental Android rig. Since it’s aging fast, I don’t use it nearly as heavily as my other Android devices, so if I accidentally do something wrong, I can live without it much more easily than I can do without a phone or my nicer tablet.
So I tend to try a lot of different things on it, just because I can.
The newest ROM I’ve tried on it is called MROM, and I must say I am impressed. Read more
I bought a keyboard this week for the Hisense Sero 7 Pro. It’s a universal keyboard/case made by Afunta, and I paid $12.50 for it. I took a chance on it, and now you don’t have to. Its spring-loaded jaws nicely accomodate the Sero 7 Pro, and the keyboard works with the Sero 7 Pro with no issues. Plug it in, wait a moment, and it starts working, replacing the onscreen keyboard when you need keyboard input, basically turning your tablet into a convertible. It has a micro USB connector, unlike many 7-inch keyboards, so it works with the Sero 7 without an adapter. It’s odd that most keyboards seem to have full-size USB connectors but most 7-inch tablets have micro ports.
I wouldn’t want to type at length with the keyboard, but it’s much nicer than using an onscreen keyboard on a 7-inch screen.
