I also mentioned that after the spring cleanup, she went five days without a crash. That joy was short-lived, as the crashes returned.<\/p>\n<p>Some days, the machine wouldn&#8217;t boot. You could hear the drive spinning, but the Post (what the BIOS shows while it&#8217;s starting up) was blank. The only reliable fix was disconnecting the battery for a minute, or worse, disconnecting the hard drive cable, and reconnecting it. Clearly, both painful solutions, since I had to open the bottom of the case to get at those devices.<\/p>\n<p>On Monday this week, neither of the above tricks worked! Oh oh, I couldn&#8217;t get Lois&#8217; machine to boot, and this was not a happy situation. Then, I got a partial Post screen (it still hung), but I saw that the number for the amount of RAM in the machine was wrong. Lois has (or had) 1GB of RAM, two sticks of 512MB each.<\/p>\n<p>The machine was now showing 512MB. So, I assumed that one of the sticks went bad. I searched online for 1GB RAM prices, and the newer DDR2 chips are so much cheaper. I didn&#8217;t care if they would run <em>slower<\/em> than they are capable, as long as they ran as well as the more expensive <em>correct<\/em> memory would.<\/p>\n<p>I decided to write to the owner of the company that I bought the laptop from, <a title=\"PowerNotebooks.com\" href=\"http:\/\/www.powernotebooks.com\/\" target=\"_blank\">PowerNotebooks.com<\/a>. I have a ton to say about them, and have been procrastinating writing a long post for weeks. I&#8217;ll get that out at some point (probably next week). I asked him whether the PC5300 sticks would work in my PC3200 machine. He cautioned me that they might not and gave me a very good suggestion on how to find out.<\/p>\n<p>But, much more importantly, he told me that it could just as easily be a bad RAM <strong>slot<\/strong> (rather than a bad RAM stick). Honestly, that never occurred to me (I don&#8217;t know why!). At the end of the day, I removed one of the sticks from Lois&#8217; machine, and it still wouldn&#8217;t boot. I moved the stick from one slot to the other, and the machine booted instantly.<\/p>\n<p>I switched the chips and the machine booted instantly. I inserted the second chip (yes, I&#8217;m using chip and stick interchangeably here) and the machine refused to boot. Voila, Mr. PowerNotebooks was correct, the slot was bad, not the stick!.<\/p>\n<p>This morning, it occurred to me that when we ordered Macs for almost everyone here at Zope, we ordered the memory separately (<strong>way cheaper<\/strong> than from Apple!) so we had extra 1GB PC5300 memory chips that we pulled from the Macs. I tried one in the good slot, and it doesn&#8217;t fit. The small slit that fits around the small plastic protrusion (forcing you to put the stick in correctly) is a drop smaller than on the PC3200 sticks.<\/p>\n<p>Oh well, at least I now know all of the answers and mysteries of the universe (or at least of Lois&#8217; laptop!). We ordered a single 1GB PC3200 stick today to get Lois back to where she was on memory. She&#8217;s been running for the past two days with 512MB, with zero crashes. Of course, we&#8217;ve gone a few days in a row before without any BSODs, but I&#8217;m betting that this bad RAM slot was deteriorating all along, and was causing intermittent (irreproducible!) errors. At least I&#8217;m desperately hoping so!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In my Laptop Spring Cleaning post, I mentioned that Lois had been suffering from daily BSOD&#8217;s (the infamous Microsoft Blue Screen of Death crashes).
