Hey all.
Posted this in the L300 thread but it seems pretty dead in there, and I have two of them waiting for a repair job. So gonna crosspost here if that's okay.
Anyway - for those not aware, these, along with many other Toshiba models, suffer from a failing proadilizer capacitor.
The cap in these two laptops is an OE907 - 2.5v/900uF/1.5mOhm ESR.
The usual procedure is to replace both these caps and the OE128s with 4x 2.5v/330uF/<10mOhm ESR.
I cannot find a single one matching on any of my scrap boards - all either have a too high ESR or 2v. I could always buy them but I cannot fathom why 4 tantalum caps cost £13 (~$19).
I do however have some 2.5v/220uF/9mOhm tantalums, quite a few.
Tl;dr: Surely a capacitance of 20uf lower isn't a major issue? Especially when there are people using a total of 680uF without an issue?
Cheers!
