Hi there folks, Long time lurker, decided to sign-up in order to be able to better tweak my 2570P. After reading this whole thread, I've installed a 3632qm which runs nice and temps are 60-65 Celcius under load. It has 2X8GB DDR1600 Kingston so-dimms which run fine. Some questions: 1) This came with an HP 19.5V PSU adapter although some use it with a 18.5V HP adapter? Which one is better? Can I damage the laptop if using the 19.5V one? Both are official. 2) If the laptop is left alone and unused for long periods of time (2-3 months), the keys on the keyboard don't register properly. You have to hit them hard a few times in order for them to start working again properly. Is this a known issue with these laptops? 3) This is a used laptop. It has some profiles in the bios and I always login as "guest" into the bios. Is there any workaround around this in order to remove the old profiles? Bios version is F65, no idea if there are better unofficial modded bios versions out there. Thanks
