in July this year,I bought 2 units of HP Probook 4445s with an AMD A6-4400M APU processor with HD Radeon 7520G integrated, & 8Gb RAM and both of them auto shut down or hybernate.I've already tweaked in Power Options & on HP Power Assistant not to hybernate;searched thru HP website via product number,downloaded & installed correct drivers,Device Manager has no warnings & says drivers are up to date;ran HP Softpaq Download Manager for latest drivers=downloaded & installed;downloaded and installed updates via HP Support Assistant;downloaded & installed Windows updates; scanned with Avira with the latest updates;disabbled Virtualization inBIOS;reformatted & installed Win7 (Home Premium,Pro,& Ultimate both x64 & x86);tried also Win8 x64; tried CPUID Hardware Monitor=temp spiked to 127 Celsius max then it shuts down,sometimes records shows between 48 & 73 Celsius before it shuts down;stable GPU Clock is at 334MHz at 43 deg Celsius;fan & vents are clean;placed new thermal compound; used i8kfangui31_x32, RM CPU Performance Test, Advanced SystemCare Pro=cleaned & optimized,MemTestx86=passed; tried booting it on clean state under system config;aimed my room fan direct on the laptop = NOTHING WORKED!!
i sent the other one to HP Service Center & got it back after 3 months but this time it freezes after a couple of hours of use. I also noticed they replaced one of the memory cards w/a different one although it says on the sticker "Kingston" but says "Nanya" on the chips 4Gb still though,while the 4Gb Hynix still there. where I come from is a place full of corrupt people.So, I got paranoid & sent it back to the Service Center. I got a bitter taste in my mouth now when it comes to service centers. So i kept the other one,continued working on it & landed here. What must I do?please help me....
