Got a call today from a longtime customer... there was a brief power outage at her house and now her computer won't turn on. Walked her through the basics - unplug for 45 seconds and then plug back in and try again... try holding the power button down for a while, etc. No go, so I swung out and picked it up, expecting a bad PSU.
Got it home and put in my testing PSU, and I get no reaction. The orange LED on the mobo is lit, but pressing the power button results in nothing. I pulled out the video card, unhooked all the drives, and pulled all but one stick of RAM. Still nothing. Pulled...

Re: The 2014~2015 Operating System Thread
I chose Windows 8/8.1, as it's the newest that I'm using. I have 8 on my work desktop, 8.1 on my work laptop, and 7 on my home desktop. I'll probably stick with Win7 on my home PC for a while... at least until 10 is RTM. But at work, we're deploying 8 on all new computers. -
Re: Trying to hack the fan on a DAS enclosure
I could source another fan with a locked rotor alarm, or apply the resistor mod... but I also found that if I just wire the fan to run all the time, the unit is happy and doesn't beep except when it initially starts. As long as you keep the drives nice and cool, it never calls for the fan to run.Last edited by dood; 11-14-2014, 10:10 AM.Leave a comment:

Re: Trying to hack the fan on a DAS enclosure
I don't see a thermal sensor anywhere on the original fan.
I plugged in a standard 80mm case fan with tach wire, and it led to some interesting behavior. When you first power it on, the unit spins the fan while beeping (it never used to beep). After a few seconds, the beeping and the fan both stopped. I let it run for a bit, and then decided to do a read scan to build up some heat. After a while, the fan still had not kicked on again, so I cancelled the scan. As soon as I cancelled the scan, the fan kicked on and the unit...Leave a comment:

Re: Trying to hack the fan on a DAS enclosure
I don't think so... aren't PWM Fans all 4 pin? This is just 3.
here's the datasheet -
It has option -53, which is an open-collector locked rotor alarm....Leave a comment:

Re: Trying to hack the fan on a DAS enclosure
It looks like I'm going to have to try swapping the fan out now. I dropped the 4 WD drives in there and the fan isn't running at all. I left it doing a read scan on the array for an hour, and nothing from the fan. I might've killed it while I was trying to jump-start it.Leave a comment:

Re: Trying to hack the fan on a DAS enclosure
it's a T92T12MMA7-53
The unit was shipped with (4) 2TB Seagate Barracuda Green drives (ST2000DL001). These drives record max temp in SMART, and after 1 drive failed I checked the rest to find that the max temp on all of them was up around 70*C. I have no real way of knowing if that counter is accurate, as it's not all that common on most drives.
What I'm planning on doing it swapping those drives out with (4) 1tb Western Digital RE4 drives (WD1003FBYX). I know the RE4's generally...Leave a comment:

Trying to hack the fan on a DAS enclosure
I've got a Buffalo HD-QL8TSU2R5 4-disk SATA enclosure that I'm working on at the moment. From the factory, the 80mm fan only runs "when needed". There's no speed adjustment or switch to leave it on all the time. What I've found is that whatever triggers the fan to come on isn't doing so often enough. The enterprise drives contained within are cooking themselves.
I thought it'd be simple enough to rig it up that the fan runs all the time. The fan itself is a nice Nidec UltraFlo rated for 12v 0.10a. My first thought was that I might be able to hack the fan controller somehow,... -

Re: Netgear FVS318
Interesting... I've bought two of these in the last two months, but didn't think to crack them open and see what was inside. We bought them to replace our old Checkpoint VPN devices at two of our branches. They perform better than the checkpoint boxes, and the price is right.Leave a comment:

Re: Dream System........back in 1999!! "Big Mama" Restored!
I remember Plextor being the standard in burners back in the day. I drooled over my Maximum PC mag announcing a 4x Plextor burner, while I was running some off-brand 1x burner that would churn out coasters like nobody's business. Couldn't do anything on my PC while burning a disk, or I ran the risk of exhausting the buffer and the burn failing.Leave a comment:

Re: The Future of the Desktop PC
I think it's a dying breed for a lot of people. Of course, in a forum of PC power users, the biggest opinion will be that they will never die...
I think a typical user can get by with a laptop. Especially the generation that's growing up now where a laptop is a requirement for college, if not also high school. I remember my sister lugging her gigantic computer (I forget if it was Dell or Gateway, but it was solid steel with a Pentium 133) to college, and just being excited that she had a computer in her own room!

Re: Dell Inspiron N7110 keyboard spill - replacement keyboard still unresponsive
So, I tore into this further today... Pulled the motherboard, went over it with a fine-toothed comb just to make sure I didn't miss any spillage. There were a few small spots, but nothing serious.
Put it all back together, still nothing. Then, as I sat here looking at it.... it dawned on me. Maybe my dumb ass had the cable upside down. Sure, the cable LOOKED right the way it was... but what does it hurt to try? Flipped the ribbon cable over, and hey presto, we have a working keyboard....Leave a comment:

Dell Inspiron N7110 keyboard spill - replacement keyboard still unresponsive
Title pretty much says it all. Got a laptop in that "won't boot" - found that it booted up fine, but wouldn't respond to any input from the keyboard... and that the keys were particularly sticky.
Cleaned everything up best I can, but I ruled the keyboard a loss, and ordered a replacement from the 'bay. This is a brand-new, genuine Dell part... Arrived today and I popped it in, only to find that the keyboard is still unresponsive. I'm guessing maybe a keyboard fuse blew (do they still exist)? Apart from going over the motherboard with a fine-tooth comb, is there anything... -
