Recently a client asked me to help them buy a new laptop. I set them up with an HP ProBook 4530. I knew it was a nice unit but was really surprised when I got it on hand. There was a really neat design surprise.
First remove the battery
But then there's no obvious way in. But a quick push of the battery latches past the battery release point and surprise!
The entire bottom cover pops forward and lifts off. Nearly all the most frequently serviced parts were right there in the open: hard drive, memory, wireless nic, etc.
Very simple. It made me wish that this kind of design had been around 8 years ago when I was disassembling dozens of laptops each month.
