If you really want to continue mining with your laptop, you can buy a laptop fan pad. I use one for my laptop because, like others have said, the dust builds up and suddenly your laptop can't cool itself unless you take it apart to clean out the dust.
Taking apart a laptop to clean the dust is not easy in the slightest. Google any youtube video... it requires taking apart the laptop piece by piece until everything is in pieces. That's how far away the GPU is from the most accessible slots. Then you have to apply thermal paste and a lot of hard work.
If you try to get a guy to clean it for you, it costs as much as a new laptop: $120.
But a laptop pad actually keeps the temperature down by 10 to 20 degrees. I've been able to mine with my laptop using it.
You can also just go full CPU mining with your laptop, which doesn't stress it out as much. Claymore has CPU mining that works with the newer alts out there. There's also an option that does low intensity cpu mining so that it doesn't cause as much heat.
if you mining using your laptop, I have a bit questions:
1. how long have you been doing mining using a laptop?
2. how much your profit?
3. is your profit greater than your electricity cost?. if you have free electricity or your parent paying you the electricity bill.(skip this question).
1. Only been mining with my laptop for a month.
2. Depends. If you're talking about current value, I'd say I'm slightly in the negative from electricity costs (and of course, this doesn't assume any wear and tear from the machinery). But we're in a bear market. If Bitcoin was 2x what it is now, mining with my laptop covers electricity costs and a little profit.
3. See 2. But then again, if i had solar panels or water power, then it would be pure profit. I'm pretty sure my laptop can last years if all it did was mine CPU.
