Well, brand new power supply and the system behaves the same problematic way as before. So next try is the memory, as another list reply suggested. I've had memtest86 running against both DIMMs for 47+ hours and counting, 70 total passes so far, and 0 errors. Remember I'd already tried removing first one DIMM, then the other, and the problem repro'd either way. So by these measures it'd seem the memory is OK? I know some mem problems take days to show up so I'll just leave this running for a couple more days anyway. Not much more I can do here, as I've seen repros with most everything else unplugged so I'm now thinking it must be the motherboard. Perhaps I will try reseating the CPU--haven't done that yet. Recall the system is having trouble POST'ing: it hangs at various points before BIOS POST completes, i.e. I don't get a confirming 'beep' at end of POST and in some cases the monitor won't wake, other cases the BIOS splash screen stays splashed, etc. The full original email is here: http://mail.wlug.org/pipermail/wlug/2012-September/008059.html Anyway, if anyone has other ideas here I'd welcome them. Thanks again, Brett

Re: [Wlug] Wlug Digest, Vol 107, Issue 13

by Karl Lind

Hi Brett, First off, CMOS checksum errors during boot refer to MEMORY not the BIOS. Also almost all your symptoms point to a possible memory issue. Do Chuck's stuff to verify that you don't have a power drain that's causing a memory issue. Get a Memory Test utility and find out which DIMM is causing the problem. Carefully remove the DIMM and using a #2 pencil eraser, clean the contacts and replace the DIMM (The rubber removes oxidation that prevents contact) and don't forget to keep grounded! (You, not the DIMM).

I agree that the power supply is suspect. You can measure the voltage on a spare power supply hard drive connector, there should be 12v from black to yellow, and 5v from black to red.

help diagnosing PC issue: suspect power supply

Re: [Wlug] Test needed on declared-ill Modem. Who has a lab?

by E Johnson

Jeff, thanks for the input on the SB6121. John, sorry to hear of the demise of your router. I have one of the newer Netgear routers here, running TomatoUSB. Very nice. It took 4 hands to do the magical reset after installing the software. but it's been solid after that. Generally, service & line issues (Charter in town here): I immediately notice line issues (when they happen) because I use an internet telephone quite often. That's one reason I like to see the modem logs. T3 and T4 timeouts might not be noticed if one is surfing the web. People streaming video might see a momentary glitch, maybe. Gamers definitely notice issues in their lines. It's not the available upload/download speeds that make the difference, it's the ping times & momentary glitches that cause packts to arrive or leave out of order, or requests & replies having to be resubmitted. Those were problems I had to address with the Charter techs at two different addresses. Line issues at the last place took me 4 years to resolve. Charter was good to me (rebates when I could prove their end caused the problems), and the techs that came out were generally okay, but didn't always know what they were doing. A lot of them pretty much just know how to measure an incoming signal, and if necessary, put a ladder up the pole & measure there... and how to plug in a modem & call the office for registration & provisioning. Other, more experienced techs would sometimes look at printouts of traceroutes, and recognize where the glitch in the system is. I think these guys are being phased out. But the internet service is generally very good. I checked again with Charter. The 3 techs who told me I'm not "allowed" to own my own modem were wrong, or misinformed, or whatever. Totally Wrong. Charter's NEW customers are required to use only Charter equipment, but customers with established accounts (before July 2012) are allowed to own their own equipment. They of course warn us that we're expected to do our own maintanence. There is a risk in this -- if the firmware (worked out between Charter and Motorola) is buggy, we'd have to prove (again) that it's Them Not Us. I have struggled with the burden-of-proof issue off & on for 12 years now. So don't go on vacation, then open a new account at the new place where you recently moved. Just migrate your account to the new location. What a Catch-22, but until we have an alternative provider in town, it is what it is. FYI on the SB6120: the price has dropped. There is free shipping on this at the moment at newegg. Mine is on order. The SB6120 (previous model) actually costs more now, where it's still available. Thanks again, guys. Hope some of this helps someone else. Liz

Re: [Wlug] Test needed on declared-ill Modem. Who has a lab?

by jeffhemstreet＠yahoo.com

Just thought I'd chime in... I have had Charter for 12+ years and only had a total of 3 outages that were more than a few hours. Dealing with customer support is usually a pain, but I try to get to a technical person by telling them I've already tried the steps as they go down their list. I bought my AMBIT 60678EU modem in 2002 from Charter, and has been good (if not solid) for most of the last 10 years. Lately I could not get a single stream downloads of > 300KB/s (SCP, peer-to-peer, etc) but speedtest would show I had 10+Mbps available. I figured the DOCSIS 2.0 and the age of that modem could be a problem so I decided to upgraded last month to a SB6121 and get the 30Mbps service. I bought the SB6121 myself and called charter to activate it. Once we go the MAC correct, and reset the modem it was up and working. Only took about 15 minutes to get up and running... including the time to "reboot my PC" which was included in their instructions. The new SB6121 has been rock solid for me and I get 4+MB/s downloads and reports of 30-45 Mbps from speedtest. Charter does let you buy your own modem and activate it but you have to call in to tech support... I found Charter's instructions for "activating" a new modem bu the web page does not work around here.

Make sure that you update the MAC address with charter, and that they actually update it. I've had a few problems where they haven't even though they said they did. Also, a lot of modems have diagnostic suites built in. An easy enough way to get at it is to turn it off, and unscrew the coax line. Now boot it up, and it won't get an IP from charter, but it should give your router an ip like 193.168.100.100, and the gateway should he something like 192.168.100.1 (check for specifics) but that gateway is your modem. Punch that IP into a browser and see what comes up, usually the password is something stupid, and a Google search will yield it if its not admin. Keep in mind you pulled the cable, so it will show that.

Re: [Wlug] Test needed on declared-ill Modem. Who has a lab?

Liz, I live in Clinton these days, where Verizon DSL and Comcast are the only options. Comcast is faster, but their monthly data caps made Verizon the better choice for me (not to mention my general distaste for cable companies). I recently had superficially similar problems. I went on freecycle and got someone's old DSL modem to swap for my own, to rule that out, but I got impatient and bought a new modem before I got the reply from freecycle. In any case, you probably can get another cable modem off freecycle for testing purposes. After the new modem didn't fix things, I finally called Verizon. They sent out a tech with a good "bedside" manner (he was friendly, seemed to know what he was talking about, and didn't talk down to me). He didn't find anything wrong with my signal, but he did notice the copper loop to my apartment was longer than necessary and cut down the excess at the pole. I haven't had any problems in the 2 months since. In retrospect, I think my problems were mostly on hot, humid days. -- Rich On Thu, Sep 20, 2012 at 7:11 PM, E Johnson <iris.gates(a)gmail.com> wrote: > Umm. Non-happy camper.

Re: [Wlug] Need recommendation on UPs for small home network.

Thank you. That helps. For quite some time I had been trying to find good answers online about whether or not I need a UPS that has "pure sine wave" output, or not. The newer "active PFC" power supplies supposedly require this. That's what I have here in the latest build. I found one on sale & free shipping at newegg for a price that won't hurt too much. CyberPower CP1000PFCLCD UPS This has only 20 reviews now, but most of the owners seem to be happy. I think this should keep the periodic brownouts from unexpectedly corrupting data. Thanks again!

Re: [Wlug] Need recommendation on UPs for small home network.

by kstratton＠fastmail.us

If this is too verbose or vague, I apologize in advance. There is no easy selection process for a UPS. Everybody seems to have different opinions on UPSs and depending on who you talk to, all may be right,all may be wrong. I have a strong preference for APC UPSs, although all brands have their lemons. The unit I have and all the units at my work all beep on and off when there is a power outage. Most UPSs have a USB cable that provides status information for a automatic shutdown. I have not used it and although I have not looked in a long time, I have not seen anything written about Linux support with APC. I have a backup XS 900 for about 5 years with no problems. The only issue for me is that it has a small fan that runs all the time. I generally only hear it when things are very quiet . I intentionally went big to extend the life of the UPS by reducing stress on the battery and maintaining an acceptable power up time on outages when the battery degrades. Yes, the battery will degrade. One thing to keep in mind when shopping for a UPS is that VA (volt amps) is not the same as watts. My personal view is that when comparing UPSs of a good brand, compare them based on watts, not VA. Where I work, we use an APC 450 for just about every PC in the place (mostly office machines). Untill recently, the building would loose power about 3 times a year. I think the battery typicaly lasts about 3 years before they need replacement. If you want to check the power usage of your computer, you may want to use a "kill a watt" or similiar device to measure the power usage, both steady state and possibly when turning the PC on. I will assume the actual power usage will be in the ballpark of 200W for the computer and reasonable monitor (light to moderate loaded cpu). For myself and limiting myself to APC and newegg, I would consider the "APC BE750G 750 VA 450 Watts 10 Outlets Power Saving Back-UPS ES". The power save feature would get in my way, but I run my computer off from a power strip so I would not use those power outlets anaway. Anything smaller, I would not be confortable assuming 5 minutes of run time for one machine. Of course, it is almost 2X the cost of an APC 450 :( Whatever you choose to use, I wish you best of luck.

Re: [Wlug] Need recommendation on UPs for small home network.

Thanks, Eric. That would work for the modem, but the computer(s) are across the room. I'm worried about the computers. Recenely had some invisible power event that seemed to crunch something in my most-important software. Had to do various softeware reinstalls, or re-specify preferences every time the power went out here, and sometimes have to do that anyway. I think I need a UPC that will deliver even voltage to the PCs here. I think I need to get one with active pfc (power factor corrected), but wanted to know if that was appropriate for my power supply, plus would run the AMD FX4100 processor & motherboard. And the router, so that doesn't need to suffer from power dips any more. I think I need something like this http://www.newegg.com/Product/Product.aspx?Item=N82E16842102139 But there are no reviews on it here yet.

I have a power strip style ups you can have, it just needs a new battery. For a similar project, I went with a smart ups 750 or 1000, and you could even go with a back-ups (both by apc, the smart one can shutdown your pc). sent from my mobile Eric On Sep 22, 2012 12:03 AM, "E Johnson" <iris.gates(a)gmail.com> wrote: > Today and the other day we discussed my issues with a modem declared-dead > by twin techs from my ISP.

Need recommendation on UPs for small home network.

by E Johnson

Today and the other day we discussed my issues with a modem declared-dead by twin techs from my ISP. Part of that problem may have been caused by bad elex service here. I need a recommendation for a UPS to use here. We have dirty elex here in this 112 year-old central Worcester house, & inadequate amperage to my floor (top floor garret). Refrig runs on same circuit as my computers do. Lights dim when something downstairs also turns on, probably a microwave oven and/or a TV. This won't be fixed any time soon unless the landlady suddenly becomes a benefactress of the Gate$ Foundation, which will never happen. I could sometime get an electrician in here to add a suitable circuit for my floor, but it would be faster & better just to get an UPS, whether or not the elex here is ever upgraded. UPS here would only need to run max 2 PCs plus their monitors, one modem and router & a light bulb or two. Really needs to run only one. The primary PC here is mine, which has a 450W power supply running a 95W AMD FX4100 quad (bulldozer) no vid card. Antec Sonata II case has 2 fans.
