Yes, the laptop is running well now, just as it was...
RJ, great to hear, I knew you'd get more opinions in the Hardware section & you have.
Glad that your notebook is now running normally again, however the issue we discussed prior, in regards to cleaning up the heatsink well & reapplying of thermal paste, will make it run cooler & last longer. You've stated in 2 other Topics other than this one, you want the notebook to run as long as possible (basically until the wheels fall off). If this is true, you'll have to do the repasting job, since 2007 when I began doing my own work, I've never left thermal paste on for more than 5 years & now use Arctic MX-4.
My main PC is just two years old & I'm already considering repasting mine because the i7-4770 CPU used to run between 28-30C, now runs at 32-36C after hours of use. Since the stock thermal paste (or pre-applied pad) is lower quality than the MX-4, probably needs replacement. I catch these deals when on promo for at least 50% off, so it's not a huge expense. Since I'm going to be upgrading to a 512GB Samsung 850 Pro SSD & removing the two smaller ones listed in my Speccy specs & placing these elsewhere, this is a perfect time to do it all. Will clean up the CPU & fan surface with 91% alcohol that I use for these things, and take the CPU fan outdoors & use an air duster to blow the fins out good in all directions. By then, all will be dry, but will check anyway, and apply a small bead, about the size of a pea or rolled oat, and when placing the CPU cooler back on, once aligned, will give a gentle twist to spread the paste & tighten the 4 screws, in a rotating pattern, in about 4-5 stages.
While it needs to be good & snug, at the same time, doesn't need to be torqued like a set of rims on a vehicle, this is how a lot of components becomes unintentionally damaged. I have some of the thread material (a tiny drop per screw is plenty), this holds these snugly in place to prevent vibration and eventually needed attention, and you likely noticed some on the ends of your screws.
If you're going to be working on a computer, having the things you need are good, and why I always buy when on promo. Have part of an open tube of MX-4, and not realizing that I already had an extra, now have 2 unopened tubes. Yet it won't go wasted, as there's two notebooks that likely needs cleaning in front of me, in addition to the main PC.
Good Luck with the computer!
