You should find it makes it into a new current gen fast laptop. 6GB is enough and from 6 to 8 or even 16GB might not give you the feels.
The Series 7537 BTX was purchased in 2014. It was slow at the time but adequate given use. Times change, use changes, speed now totally unacceptable.
Pertinent machine info:
1. 750GB 5400RPM SATA HD
2. 4th Generation Intel Core i5-4200U Processor (3M Cache, up to 2.6 GHz), UMA, C1
3. 6GB Dual Channel DDR3L 1600MHz (4GBx1 + 2GBx1)
Assuming I can do so, my thinking is to switch out the HD for an SSD for the best speed/model the BIOS will allow.
I do not know the max RAM for this machine. If it's 8 I'd toss what's there and replace with similar Crucial 8GB.
If I'm wasting my time/money--please say so.
If the idea is sound but what I'm doing needs altering--please tell me.
