1987 BMW 325e goes into "limp home mode" in snow and rain

(this was written some time ago but placing it here for posterity)




I had acquired a 1987 325e in the summer of 1999 with 73k miles, fairly low mileage for a car of that vintage. It had been fairly well maintained with a few outstanding issues.

The first indication of this problem was the first snowstorm of the winter of 1999-2000.While driving home during a late night snowstorm, the car went into a strange mode where it would not stall, but it would only produce 1000 rpm even if the accelerator pedal was pressed to the floor. The car would make progress at 5 to 10 mph, even going up gentle hills.I parked the car just glad to have made it home.

The next morning it started up and drove fine. The problem was quite unusual and I planned to speak to my mechanic about it. When I did have the conversation,the mechanic was not able to shed any light on the problem.

Over the next 3 years the situation repeated itself, something like 10 or so times. Most dramatically, it would happen during sno…

Fedora 14 Hangs - PS2 Mouse is Bad Mmmkay - SOLVED

PS2 Mouse and Keyboard Things would work great for about 5 or 10 minutes and then the system would lock up.

The various Linux message boards are full of descriptions of this sort of thing and most folks thing that this is a mixed bag of problems - similar symptoms but perhaps a large variety of causes. Hard to say without having a definitive analysis of each instance.

There are lots of "home remedies" - changing kernel versions, changing video drivers, changing the boot parameters for the kernel, changing xorg.conf, etc. but again, these are hard to evaluate for sev…

Dogtra 3500NCP SuperX - backing out case screws is a bear!

I have a Dogtra 3500NCP SuperX shock collar. Without it my Dobie would not get any exercise because he'd play "keep away" whenever I threw his favorite ball for him to fetch. With a little "gentle reminder" he comes back and the cycle can begin again.

The collar worked well for about a year and a half but then the transmitter part wouldn't hold a charge any longer. A replacement battery can be purchased and they offer to do the replacement for you but that would entail a service charge not to mention shipping it there and back. So I ordered a new battery? How hard could it be to change a battery?

Answer? Very hard. Very hard indeed.

The 6 screws that attach the back of the case to the case itself are CEMENTED into the plastic. Or might as well be. With a screwdriver that was just the right size I was able to back out four out of the six with a fair amount of difficulty. The other two (i.e. the bottom left two in the picture) were n…

Awkward! (Realtek RTL8111/8168B PCI Express Gigabit Ethernet controller in "awkward" mode)

We hear new expressions from teens and twenty-somethings all the time - and they usually get real old real fast. But there is one semi(?) current expression that I like a lot - it's where kids say - often as a sing-song chorus - "AWKWARD" - in response to someone else describing a situation that is, well, awkward.

Well, even though I basically do networking for a living, I'd never heard of "awkward" mode as applied to a Network Interface device like an Ethernet adapter. Promiscuous mode, yes. But awkward mode no. That is until yesterday.

Here's what happened.

My dual boot machine (Win7, Fedora Core 14) was running Windows 7 and there were some Win 7 OS updates that I said yes to. I was later able to verify that one of these updates did include a driver update for the Realtek PCI Gigabit Ethernet onboard NIC. Things were working fine, I left and I guess the updates installed themselves.

When I returned there was no network connectivity. Not in Windows…

HP Photosmart C8100 All-in-One won't print (Printer says "out of paper" but need to pull back the blue photo tray).

Mine's a C8180. Everything looks fine. You print a test page and the rollers spin for ten seconds or so and then a non-helpful message appears on the printer saying you're out of paper. Except you're not.

You RTFM. No help.

You go online to HP's troubleshooting guide for this exact problem and they have a detailed list of things to try except none of them fix the problem.

I figured this one out myself but if you look here somebody else did too

yoofahsays: 30/08/2010 at 04:43 Another possible issue not identified in the video:
these printers are equipped with a blue “photo tray” in the main paper tray area. If this is pushed in, it’ll try to draw from that instead of the main train tray, causing this same type of error. The solution is to reach your head in, and pull out that blue tray until it is flush with the main tray.
Yeah, you need to pull that little blue photo tray back a few inches and - voila - the printer prints again. (I don't think yoofah meant to reach…
