I have a HP Pavilion ZE 4522EA laptop here of which the power supply
crapped out. The power supply of this unit is rated at 90W.
Now I have another (universal) power supply laying around with a max.
output of 77VA.
If I remember correctly from school, VA=W, right?
Will this power supply work with the laptop? Can I expect any problems?
Re: a 77VA PSU on a laptop that needs 90W. Will this work?
anyway. How lucky do you feel today? The chances of doing any damage
to the laptop are relatively small (however, they are not zero). The
chances of doing damage to the power supply are somewhat greater. If
you do elect to proceed, monitor how hot the power supply gets.
VA = watts for DC (which this is). For AC, however, VA may be
[considerably] different than watts. For AC the relationship is complex
and difficult to explain to a non-engineer.
