The drive from Palm Springs to LAX on a weekday afternoon avoids some of the rush hour traffic flow, but still would make me cautious enough to give myself ample time to get there - 90 min might be a little optimistic. I'd probably be on the road no later than sometime between 12 Noon to 1 p.m.
If you take a look at a road map, here's the routing I think might work best.
HWY 111 out of Palm Springs to Interstate 10.
I-10 West to Interstate 605
I-605 South to Interstate 105 (there is an HOV lane on the 605 that you can use, but you'll need to exit it to transition to the 105)
I-105 West (HOV lane on the 105) to LAX.
