Hi Buddy... I washaving trouble with my Gateway 4530 GZ. I took it to three repair shops and they all said the same thin - "it's the motherboard and would cost more than the laptop is worth to fix it". Well, I decided to buy a motherboard and replace it myself! Hell, it was already broken so Icouldn't do much damage.
I just went to www.ehow.com and asked "How to replace a motherboard on a Gateway 4530GZ. The instructions were very clear. It was a little complicated - but not impossible. And guess what??? I spent $49.00 for a motherboard on e-bay, made the repair myself - and IT WORKS LIKE NEW!
Give it a try - it's well worth it.
