I recently found a Lenovo Ideapad y510p at a Pawn Shop for $250, which isn't bad at all considering the specs for an older laptop:
CPU: Intel Core i5 4200m
Ram: 8GB DDR3 1600
Hard Drive: 500GB
Graphics: NVIDIA GeForce GT 755m SLI
OS: Windows 10
After purchasing I decided to go ahead and upgrade the CPU to an i7 4800mq. I've been able to play games without issue as long as SLI was disabled, but when games use both cards, after a few minutes frames start dropping and game either freezes or crashes. I noticed that when the frames drop, the laptop is temporarily switching to battery and back to AC. The laptop came with the "170 watt" power adapter (which is the maximum size adapter for this laptop). I know there were versions of this model that came with an i7 and same video cards so I didn't think it would be lack of power. Would simply replacing the power adapter fix the issue?
If I do replace it I've seen that there are 180watt universals out there that would increase the wattage threshold a little bit, but they only come as 19volt or 19.5 volt. The laptop states on the back that it needs 20volts and that is what the stock adapter is. Would undervolting it by 1 volt hurt it?
