I think that's RAM. 3 beeps is usually RAM. Pull a sodimm and see what happens. P30 usually had two sodimms. Try it with one, then the other, then none. Let us know if the beep codes change.
Yes no more Bip problem One is solved now.
But a new problem apeared.
I start computer, I see the starting Toshiba Logo with the command (f2setup and f12 boot) for less than 1-2 sec. After computer shut-down...
I tried to go in setup or boot none work (f2 and f12)
It's realy strange never had a problem like that before.
I have only one 512mb sodimm I tried it on both slot .. same result each time.
