    My EP121 has recently developed a sporadic fault which makes it spontaneously close down. This started after I replaced the battery, but this might be a coincidence.

    Although the close-down can happen without any obvious trigger, it quite often seems to be triggered by flexing or squeezing the lower (long) side.

    I also wonder if it is heat-related. SpeedFan tells me the disk and cores are running a bit hot: typically 60C and 53C respectively.

    Thanks for any input.

    What if you use the old battery again tocheck if it shut down..
    that temp is not the above the intel spec..

    Thanks CF77, I'll try next week when I'm back home. The reason I changed the battery was that I was getting "You should change your battery soon" messages.

    I've now had the chance to try the old battery, and the behaviour is no different (except that
    the charge runs down very quickly).
    It's odd, because the machine will run with no problem for several days and then have a period
    of constant shutdowns, sometimes even before it has properly (re)started. I still think it is
    heat-related: what is the operating range for the processors? SpeedFan also reports a "Temp 1"
    which is consistently about 10° C above the core temperatures. I've not been able to find out
    what this relates to.

    can you measure the temp on top of cpu?

    Do you mean externally, or sensed internally? SpeedFan gives 3 readings, which at the moment are Temp1: 56C; Core0: 50C and Core1: 48C. Problems are more common with readings 5 to 10 degrees C higher

    Microsoft Security Essentials tells me there are no problems. Is this good enough?
