Hello all, I'm first time there, hope it's right place to write.
I got for reparation an ASUS EEE PC 901 XP notebook. Simptoms: connecting AC adapter causes battey LED blinking instantly about 2 times on a second, laptop (motherboard's speaker?) makes short clicks with a quiet high tone in the rhythm of LED blinking. http://cdn1.eeepc.it/wp-content/gallery/eee-pc-901/eee-...
(it's second on the left, pic taken from google, on my laptop all other leds are blank)
I found POST signals explaination on ASUS site, but they don't fit. Pressing power button makes no reaction. Blank screen, fans dead. When battery powered, laptop doesn't react at all. I remember it did have the same LED blinking effect on battery when pressed power button, but not sure now. Battery probably got discharged long time ago and I saw this only once.
AC adapter has 12,24V, as it's supposed to. I found over the net solution telling me to disconnect CMOS battery - I did for the whole night, didn't help.
Inside the laptop I found such thing: http://pliki.netau.net/images/img017dhd.jpg
sticked on the glue of CMOS battery. I remember there was something floating inside since it was new, don't know what it is and if it could make there problems, though.
