Answer 1

yes..
your numbers indicate 19Vdc at 90 watts

===========================
it's usually around 18vdc..
17-19VDC is the usual range and is ok for universals.. (10% tolerance built into all circuits :) )
If you get a universal replacement you should be ok.. ALL you need to know is the VDC needed by laptop. usually written on a label on the bottom...
====================================
My wife's compaq power supply runs my gateway perfectly... There's only one catch..my gateway adapter WOULD run my wife's compaq IF the adapters output plug was longer....

looking up yer laptop......

heh! yep..that's you!!
Power Rating: 19.5 Volts 7.7 Amps.

$85 here sadly about right... you can find a better price...

If you need immediate gratification try staples or Bestbuy or circuit city.. MAYBE even walmart....(Yes Walmart's carrying laptops now...that should include universal adapters...)

In fact..there it is...

The HP laptop motherboard uses EXACTLY the same adapter as my wifes compaq.. and lloking at the images.. the plugs long as the one for you computer so you cold use that...$69 is a decent price....(that should be yer 90 watt model too!!)

Staples has a better price tho...$59 AND it comes with various adapter plugs to GUARENTEE connection...

BUT it's not 90 watt the 90 watt was discontinued and they are going withe the 75 watt...
I DO NOT RECOMMEND THE 75...IT WILL HEAT UP AND POSSIBLY BURN OUT ON YOU.

(but if you check with them they may have another 90 watt that's not listed online.)

Happy to help (Happy Computing!!!)

Just to clarify....if you get a 180watt or any watt higher than 90...then the adapter will run cooler as it's not being worked as hard.... but the VDC should be between 18.5 and 19.5... 90 or better for the WATTs

but..
too low a VDC and laptop will either ignore it or not charge up all the way... too high and... crispy fried laptop :)

So stay in the lines for the VDC...(Thankfully Sony didn't go with some WIERD voltage that FORCES you to use thier adapter only...like they do for some of thier stuff....)
