hello all - I bought a semi late model Sony Vaio laptop from a local
individual here with a broken DC input jack. Nice unit, thin, PIII 800, etc
but after installing a new DC jack, it appears the board is dead. My tech
says that the unit is getting power thru the new DC input all the way to the
switching circuitry. He doesnt have schematics for this model but he
believes the switching circuitry receives some sort of signal before it will
allow power-up to the rest of the board. Been doing some net research on
this line and it looks like this is a common problem with these units.
Several for sale on Ebay with similar symptoms.
The seller believes this unit will power up thru a dock station and I have
read one account of a unit with similar damage would only power up thru the
dock.. Is this possible although the unit will not power up thru the
external power inlet? Also, the battery appears to have an open circuit. Do
the Sony Vaio batteries have complex design such that a working unit would
appear to have an open circuit?
Appreciate any help or commentary.
