I have an HP HDX16-1155CA from April 2009. I was using it last night, and it was completely fine, and I did not do anything abnormal (I was reading my book for English class before I shut it down).
Today at school, I booted it. The screen was black and did not show anything at all, the DVD drive spun twice (Usually it spins a LOT more). Don't think I heard my hdd spin but I could be wrong. HDD light wasn't on. Num lock and Caps lock lights were on. There was nothing else. No response from pressing any keys, or waiting. All I could do is force it to shut off.
The same thing happens when I run it with the power cable. I also tried taking out the battery, power cable, and holding then power button for 30-60s. Nothing works.
Last Friday (Today is Jul 18, 2012, and that was Jul 13, 2012), I took it apart to remove the sticky dust from the fans, and to replace the dried up thermal paste. It worked very well for this time until today.
I don't know if anything has been fried. I live in southern Ontario, and it's very humid and hot right now. Idling temperatures are about 48-50 C for the GPU, and about 45 for the CPU when I use it. It sits on top of a cooler, and I turn it on sometimes but it doesn't do a lot.
Is my laptop done? Did anything get fried? A classmate told me that her brothers had a couple HPs and they all failed in 3 years. Is there anything I could do to fix this?
