The missing Lenovo Thinkpad scroll lock key

One of my coworkers accidentally enabled scroll lock on a Lenovo Thinkpad L440 the other day, which is bad news when you do it accidentally and can’t find the missing Thinkpad scroll lock key. Read more

SSDs, data loss, electricity, and hype

Dave Farquhar Hardware, security , , , , ,

I’m not particularly worried about this, but under the very worst case scenario, certain solid-state disks can theoretically lose data in a week or two if they’re left without power. But that doesn’t instill panic and get clicks when you say it like that.

But you knew I was going to write about it. Let me tell you why I’m not worried.

Micro Center sells a pair of $5 USB-powered speakers. You’re either going to read the next sentence or you aren’t.

Still with me? Great. Let’s talk about them.

Using the OSI model to troubleshoot video

Dave Farquhar Hardware, Troubleshooting , , , ,

I was at church on Sunday and the video projection wasn’t working. After a few minutes of watching everyone struggle, I volunteered to take a look, and working together, we were able to get the video working again using a simple, repeatable methodology: Using the OSI model to troubleshoot video.

I’m going to share that methodology now.

If I were buying an SSD today

Dave Farquhar Hardware , , , , ,

SSD pricing continues to be competitive, and if I were buying an SSD today, I would have a tough decision ahead of me. The Crucial BX100 would be the obvious choice, with its good speed, super-low power consumption, and attractive price, at $99 for the 250GB model and around $185 for the 500GB model.

But there’s an underdog: the PNY CS1111. Bear with me on that one: It’s a little slower than the Crucial, but costs 15% less.

A simple fix for an Asus Memopad 7 that wouldn’t charge

Dave Farquhar Android, Hardware , , , ,

I’ve written enough about the Asus Memopad HD 7 that you can probably surmise I’ve had a few issues with them. Fortunately the fix is usually simple, and in the case of a Memopad that won’t charge even after you did my battery fix, that’s true as well.

It started with my observation that the USB cable fit rather loosely into my sons’ tablets. I cleaned out the mini-USB port with a wooden toothpick, which is a common fix, but it didn’t help–the cable still fit very loosely and the device wouldn’t charge.

Then I tried other cables. I found most of them didn’t work either. If I set something heavy on top, they would charge for a while, but doing that caused the cables to wear out in a matter of weeks. Finally I figured out the tablets are just picky–or at least they are once they get some age to them. The charger for the Moto E, which has a hardwired cable, works fine. So does some other random cable I had that I never used for anything else because it happens to be so short it’s not useful for anything else. I bought some new Monoprice cables, and while they’re fine for data transfer, these Memo Pad 7s don’t like them for charging.

I really hate to say try every USB cable in the house, but… your best first step is to try every USB cable in the house. And if you have to buy a cable, buy something locally, ideally in a store that will try it out with you before purchase. If you don’t have a store with that kind of service near you anymore, then buy a cable and try it out in the parking lot in your car right away before driving home. That way you can exchange the cable right away, or get a refund, if it doesn’t work any better than what you already had.

Buy as much computer as you need

Veteran IT journalist Guy Wright advises not to buy any more computer than you need. Wright was a prominent Commodore journalist, so he’s been thinking this way for literally decades. I grew up reading the magazines he edited in the 1980s and 1990s–yes, really–so it’s not surprising that I would agree with him.

I saw a couple of points worth clarifying.

New options for low-TDP PCs

Dave Farquhar Hardware ,

Earlier last week, Intel quietly unveiled a new series of Braswell SoCs, intended for very low-TDP PCs. Literally low-power, as the chips use between 4 and 6 watts. Add the requirements of the motherboard, memory, and an SSD and you’re probably still looking at a computer that uses less than 15 watts.

The SoCs are priced between $121 and $161, which probably means the motherboards will run between $140 and $200 depending on the feature set. Add memory, a case, power supply, and an SSD, and you have a silent, power-sipping computer.

So far only MSI has announced motherboards and they haven’t announced pricing, but given Asrock’s selection of boards featuring previous-generation 6W TDP CPUs, I expect at least Asrock will join in, and probably Asus will as well.

These aren’t powerhouse machines, but they’re fine for everyday use, and someone like me who has a 7-year-old PC that works fine could think about replacing that machine with one of these. It’ll be marginally faster, but with the difference in power consumption being nearly 100 watts, the computer will probably pay for itself eventually. Or go grab one of the previous-generation boards, which sell for well under $100, and settle for less performance but a faster payoff.

How to roll your own mini PC and potentially save

Dave Farquhar Hardware , , ,

I’ve talked at length about HP’s new mini PCs, but there are some alternatives in the DIY space. For example, Asrock offers the D1800B-ITX, which sells for around $53. Going the DIY route, you won’t get a discounted copy of Windows, but you also won’t spend money on RAM and an SSD that you’re going to end up replacing and you can get exactly as much CPU as you want.

How to convert any ATX or microATX case to silent operation

Dave Farquhar Hardware ,

Now that SSDs and CPUs that consume 10 watts are readily available and inexpensive, it’s possible for almost any mainstream PC to be a silent PC. You can of course buy new cases for silent-PC builds, but if you want to upgrade and save a little money while doing it, you can easily convert a legacy case of almost any age to work silently. If you have an AC adapter from a discarded or disused laptop or LCD monitor, you can do this project for less than $30. Here’s how.
