Hi look I have been using computers for 15 years or so and am an old git (55) and have had the very same issues on my HP Pavillion Pavilion DV6000 (3.5 years old) from this morning.
Previously had the wirless card issues and had fan / bios thingy upgrade and been back to HP 3 times in 1st 2.5 years (extended warranty due to known issue)
Closed down fine 8 hours ago in early hours so assumed not hardwear failure as such, and spent 30 mins looking on forums from my desktop upstairs for an answer as I, like us all these days, needed the work on my laptop or I was screwed.
Well you will love this one, after trying the battery thing, you know:
unplug the power cable, remove the battery, hold down the on/off button for 30 seconds to dissipate electrical static = it still wouldnt power up!
My wife who incidentally cant find the on/off button on a computer and who keeps her 10 year old mobile cause its the only one she knows how to use said to me:
'Bob you use it on the arm of the sofa then put it on the carpet next to the sofa when you have finished so its probably all that dust inside'
Yea, I thought the same 'stupid female dont be daft'
Anyway just before getting a rope to hang myself I thought why not, so I got my can of Staples (or any) Air Duster, which if you hold it down for more than a few seconds the solvent carrier comes out as well and I removed the battery and sprayed all the air holes on my laptop, especially around the power connector and wow was I amazed at how much dust came out!
Wife says 'hey dont laugh, thats the same as altzheimer sufferers, they get some stuff on the brain that blocks the normal flow of electrical things'
RESULT = I AM TYPING THIS ON MY LAPTOP!
I am not a tech freak, I am old, read some real rubbish on forums, oh and I love my kids to bits and I swear on my kids lives that the above is all 110% true!!!!!!!
