I just bought an HP refurbished laptop mostly because of the quad-core processor and option to upgrade to 16GB RAM.
Is HP known for having heating issues with their laptops? My mom has an old HP laptop, the Pavilion dv2000. That and the dv9000 had a known heatsink issue. Other than that, I kept getting CPU warnings (not heat warnings) while browsing yesterday on Pale Moon with two tabs open. I suppose it was because it was on my lap with no flat surface underneath, but that has never been an issue for me with other brands.
