OK … not quite, but close enough. \u00c2\u00a0I’ve now noticed that when running Chrome (in my typically abusive manner — with 15-30 tabs open for my queued up reading matter slash multi-tasking), my CPU temperature rises about 2-4\u00c2\u00b0 (C) due to the Chrome hammering of the CPU. \u00c2\u00a0Is that an essential design trade-off (separate processes per page = constant processing of javascript, Flash, etc.), or is this just an (incredibly annoying) implementation defect, and will a future version of Chrome hibernate the processes\/pages that aren’t currently active\/visible (if I can’t see it, either turn it off, or nice it down so far that it won’t substantially impact the CPU). \u00c2\u00a0As it is, if I leave Chrome running (again, with many tabs), I typically see CPU usage > 75%, and eventually approaching > 95%. \u00c2\u00a0Luckily, Chrome has automatic saving of current tabs … so it’s a breeze to just start and stop it at will (hint, Firefox: \u00c2\u00a0stop asking me if I want to save my current tabs … of course I do!).<\/p>\n
But why am I now monitoring the Chrome effect on my CPU temperature? \u00c2\u00a0Because earlier this week, in the midst of all sorts of irreproducible work (of course), my 3-year-old Lenovo T42P abruptly quit, and wouldn’t return to life. \u00c2\u00a0BIOS diagnosis: \u00c2\u00a0fan kaput — and to the point, the notebook would shut down immediately thereafter.<\/p>\n
Took the old fan out, which was very easy, following the instructions in the clean T42 Manual<\/a>. \u00c2\u00a0For finding the right part number (a cutely named FRU = “Field Replaceable Unit” … guess I’m in the field now<\/em>!), I used the Service Parts Diagram for the T42p<\/a>. \u00c2\u00a0Turns out that my part number –\u00c2\u00a013R2657– has been replaced by part number\u00c2\u00a041W5204\u00c2\u00a0(confirmed in the Thinkpad forums, and also by IBM NL). \u00c2\u00a0Since I’m in the Netherlands, I had to order from IBM NL … they were pleasant and efficient, and I received the fan overnight. \u00c2\u00a0Putting the new fan in was a breeze.<\/p>\n Disturbingly, though, the Thinkpad booted up, but then would quit after 10-20 minutes … and by “quit”, I mean: \u00c2\u00a0turn off abruptly, with no traces left in the event logs. \u00c2\u00a0Not so cool. \u00c2\u00a0So I installed “Emeritus'” Windows Thinkpad fan management app<\/a> (if you’re running Linux on a Thinkpad, there’s a whole host of app support for you … Google it), as discussed in this thread<\/a>, set it to be a bit more aggressive about kicking the fan up in response to temperature steps … and … so far, so good. \u00c2\u00a0I’m holding at about 53-54\u00c2\u00b0 C when on battery, even with my Chrome abuse.<\/p>\n","protected":false},"excerpt":{"rendered":" OK … not quite, but close enough. \u00c2\u00a0I’ve now noticed that when running Chrome (in my typically abusive manner — with 15-30 tabs open for my queued up reading matter slash multi-tasking), my CPU temperature rises about 2-4\u00c2\u00b0 (C) due to the Chrome hammering of the CPU. \u00c2\u00a0Is that an essential design trade-off (separate processes … Continue reading “Chrome ate my Thinkpad”<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[5],"tags":[],"_links":{"self":[{"href":"http:\/\/eggblog.invertedegg.com\/index.php?rest_route=\/wp\/v2\/posts\/8"}],"collection":[{"href":"http:\/\/eggblog.invertedegg.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/eggblog.invertedegg.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/eggblog.invertedegg.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/eggblog.invertedegg.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=8"}],"version-history":[{"count":1,"href":"http:\/\/eggblog.invertedegg.com\/index.php?rest_route=\/wp\/v2\/posts\/8\/revisions"}],"predecessor-version":[{"id":9,"href":"http:\/\/eggblog.invertedegg.com\/index.php?rest_route=\/wp\/v2\/posts\/8\/revisions\/9"}],"wp:attachment":[{"href":"http:\/\/eggblog.invertedegg.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=8"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/eggblog.invertedegg.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=8"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/eggblog.invertedegg.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=8"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
