Follow-up on the Insignia NS20EM50A13 monitor

Dave Farquhar Hardware January 20, 2013January 20, 2013acer, hp, insignia, Micro Center, VGA

After about a month with an Insignia NS20EM50A13 monitor, I still mostly like it, but can note one annoyance. When booting up a system, the monitor sometimes likes to switch from the DVI input to VGA, without warning. If you happen to be sitting there when it happens, you notice it and can switch it back. But more than once I’ve rebooted, walked away, come back a few minutes later and wondered why I have a weird black screen in front of me instead of a logon screen. Read more

R.I.P.: Netbooks

Dave Farquhar Hardware January 1, 2013March 30, 2024acer, asus, garage sale, hp, Microsoft Office, netbooks, office 2007, playstation

The last two netbook vendors standing, Acer and Asus, have both announced they’ve produced their last netbook. So they’re joining the Playstation 2 in the land of the digital dinosaurs, though I suspect more people will miss the 12-year-old game console than the netbook. The Guardian has an analysis, but basically they blame the emergence of tablets, and the increased cost of producing netbooks with Windows.

Review: Insignia NS20EM50A13 monitor

Dave Farquhar Hardware December 18, 2012November 23, 2016best buy, dell, hp, insignia, lcd monitors, power brick, power cord, VGA, windows 7

My 15-inch Dell LCD died this weekend. Its date of manufacture was October 2001, so I can’t complain. I bought it used a number of years ago and paid a pittance for it. It had been acting up for more than a year, and at least it had the decency to wait until a potential replacement was on sale before dying completely.

Best Buy had its house-brand 20″ LED monitor on sale for $90, and I had a gift card with a few dollars on it, so I braved Best Buy again, and found a good low-end monitor for the money. Read more

The trouble with Dell

Note: I wrote this in mid-2010 and, for whatever reason, never posted it. I found it this week. Although the information in it is no longer fresh and new, it’s still useful, so for that reason, I’m posting it now.

Dell is standing on some shaky ground right now. Bill Snyder has a good summary of the problem.

In recent years, Dell computers have, shall I say, made me nervous. Some of it’s been concrete. Some of it’s just been touchy-feely. Now one of those touchy-feely problems is more concrete. Read more

Reduce your RAID failure rate

Dave Farquhar Hardware, security November 5, 2012April 18, 2017compaq, dell, hp, raid array, Western Digital

It’s not often that you end up talking about computer hardware at church. It’s especially not often that you end up talking about a RAID failure at church. But one such conversation got me thinking again about ways to reduce RAID failure rate.

This past Sunday, I talked with the executive director, who told me five of the drives in the 8-drive RAID array failed all at once. “That’s not supposed to happen,” he said.

It isn’t. But I know why it did.

Cable connections are the last thing most people check…

Fed up with trying to host a network printer on a Windows 7 box on a mixed network, I broke down and bought a Jetdirect card for my aged HP Laserjet 4100. Don’t worry–used Jetdirect cards are cheap these days. I paid $7 for mine.

Of course I made installing it harder than I needed to. I’m a professional. Don’t try this at home. Read more

This Linux Mint box looks really nice, except for the price

Dave Farquhar Hardware, Linux June 27, 2012June 25, 2012android, apple, dell, hp, Linux Mint, ubuntu

Linux Mint (a close cousin of Ubuntu) now comes bundled on a nice-looking small form factor PC–a small metal box, comparable in size to a home router, ideal for connecting to a television to use as an HTPC and/or as a secondary PC.

Entry-level troubleshooting

Dave Farquhar Hardware June 15, 2012November 3, 2025antivirus, Ars Technica, capacitors, dell, hp, IBM, power button, troubleshooting

Ars Technica offers a very good, brief guide to troubleshooting computer hardware. Being two pages long, it doesn’t tell you everything, but includes some good tricks, including one I don’t always remember to tell people. To fully discharge a device, unplug it from the wall, remove the battery if it has one, then press and hold down the power button for 10-15 seconds. This discharges any power that could be lingering in the capacitors inside. Read more

The future of flash memory might not be so bleak after all, either

Dave Farquhar Hardware February 24, 2012February 26, 2012hp

PC Perspective’s Allyn Malventano stopped in earlier this week and sent me a link to his take on the bleak future of SSDs and flash memory: http://www.pcper.com/reviews/Editorial/NAND-Flash-Memory-Future-Not-So-Bleak-After-All

He didn’t agree with me entirely–he argued that the problems outlined in the study in question are solvable.

SSD future isn’t bleak, just flash

Dave Farquhar Hardware February 17, 2012computerworld, hp, kingston

Computerworld is predicting that the end of the line for SSDs will be the year 2024.

That’s based on the projected year MLC flash memory becomes impractical to continue producing. There’s one problem with that assumption: it assumes SSDs will still be based on flash memory in 2024.
