Now you can set custom _PSV, _HOT and _CRIT. Worked well for me on my previous HP Pavilion dv6 series laptop. More complex resolution of overheating problem - consider to sell HP asap and get any other laptop. HP totaly failed on cooling on almost all models, they are all hothothot. -- () ascii ribbon campaign - against html mail /\ - against microsoft attachments
