Suddenly the display went dead during a boot-up sequence. You could hear the fan start and the battery seemed to be charging but nothing else. Tried all the usual including checking the RAM but no luck – it remained dead. Whilst taking the laptop apart a problem with the backlight wiring was observed. This proved to be a diversion of little consequence. There the laptop lay for about a month or two whilst I built up enthusiasm to start looking at the motherboard. It was then powered up again, and not unusually, the fault had disappeared, (it happens more than one might think). Basically, all it needed was a CMOS RESET. It apparently did this by itself. The battery had been left out whilst partially dissembled during those months and coupled with the CMOS back-up battery being effectively – dead – the system reset. Had the main battery been left in the fault would have still been there. Somehow the boot-up sequence had got scrambled at start up! There is a moral there somewhere.

Perhaps the video maybe of use to anyone messing around with a 1525 but let’s face it. “ Who in this day and age is going to be taking one of these apart?”

If I haven’t said this before, an apology for repeating myself (It’s an age thing, ones mind wanders when doing the boring bits like replacing screws).
