I have a G70-129EA Laptop and wanted to put more memory in it. I know that the orginal specs said the max memory it can use is 4GB but is that because its running 32 bit windows?
If I upgrade to 64 bit can I put more memory in it ? Say 8gb or 16gb ?
(I know it has dual memory slots so can put 2 x 4gb etc in)

It is an older machine using an older type of memory, DDR2. Quoted from the service manual:
Supports up to 4 GB of system memory
Supports PC2-6400, 800-MHz, DDR2 and PC2-5300, 667-MHz, DDR2
So the 4 gigs is a hardware limitation, not caused by 32 bit Windows. Some other similar HP laptops from that era will run 8 gigs of DDR2 using the same processor and chipset combination. When the laptop was made 4 gig modules of DDR2 were pretty rare so the Manual just may not consider that possibility. However, 4 gig modules of DDR2, while available, are very expensive. An 8 gig kit (2 x 4gb) of any reputable brand is going to cost well over $100. 16 gigs of DDR2 is not possible as there are no 8 gig chips. It is not worth it for that laptop to go beyond 4 gigs in my opinion. Run 4 gigs of memory on 64 bit Windows, and spend that same $100 or even less on a 240 gig solid state drive and you will get the speed you are missing from it.
