The 4894s on my T23 motherboard look to be power MOSFET transistors. I had one like it turn into an LED a couple of weeks back.

thanks "ray ?"

they could be i looked/ searched through rs but no luck ,i bet there very generic it terms of type like bc108 these are on the underside
i do think there power devicessome of the legs are gone and zero power on the board , i reckon these or similar are the suckers that go awol on t20,21.

thanks ian

Hrm... if power was applied then the corrosion is probably too extensive to reclaim them.

Any way you can get us a picture of the little buggers?

sorry about delay replying

the legs have gone i will try to get a picture though i have been distracted by another t30 ,got this onerunning with a 4200 hd i have to say all round as much as i love my t23 (1.2g cpu,fully maxed ram and 7200 hd ) i prefere the t30 this is 2.0g and even with the slow hd and lesser ram it is pacey although very slow loading up xp .
i have to clear the sitting room floor of laptops by sat night before wife comes back from france , so will take pic before i clear up.

i bought a dvd rewiter with dual layer but the scally wag failed to mention it was region 1 i need reg 2 it has no changes left anyone have some software to reset this

thanks ian
