I hope that someone may be able to advise. I spilled a small quantity of liquid on my T42 Thinkpad. I dried it off immediately and put the laptop in the sun to allow any remaining liquid to evaporate. It was still on and functioning throughout this procedure. I left it for about 10/15 minutes out on the balcony and when I came back to check on it, it had gone into black screen screen mode and was saying there was a fatal error and was performing a physical system dump or something on those lines. The machine at this point was extremely hot to touch which I presume is due to having been left under fairly strong sunlight for 10/15 minutes.
I switched the machine off with the on/off button and have since attempted several times to switch it back on but each time it reaches the same point and won't go any further. At this point it says "Intel(R) Boot Agent GE v1.2.17
