I tried all the power schemes available: home/office desk, always on, minimal power management, max battery, presentation, portable laptop... but none of them change anything. The only difference they make is that you can set how long to wait before turning off the monitor, hard disk, blah blah...
My zv6000 laptop is about 5 years old. when it was about three years old, the F8, 8, I ,K, comma, keys stopped working(they are all in one line.) It was probably because of some circuit or dust problem that the 5 keys (in a diagonal line) stopped working. Then a few months after that, all the keys stopped working suddenly, and at any random time, one key would continously be entered, like ttttttttttttttttttttttttttttt or kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk , etc.. I would have to sort of put a lot of pressure and sweep over the keyboard forcefully pushing all keys to stop the tttttttttttttttttttttttttt
and kkkkkkkkkkkkkkkkkkk... But the problems didn't go away. Then, I opened up the laptop and disconnected the keyboard cable from the motherboard. But ridiculously and ironically, the keyboard would still enter any random key repeated(usually ctrl), even though it was disconnected from the motherboard!!!. Then, after a few days, it suddenly stopped doing that. Now i have a totally useless and non functional keyboard (no response on pushing any key, sometimes starts entering repeated keys like before,then you have to restart to stop that.). (now it rarely does that.) other than that, there's not much to say about the keyboard. The warranty had been over before the troubles had started. (By the way, i upgraded my laptop's ram from 512MB to the 2GB max a few months ago, to be able to run my animation software well(flash CS4,photoshop,etc).. The keyboard's still disconnected, and hasn't shown any hope of working again. I'm almost an expert in computer hardware, [way ahead of my age(14)], and i tried my best to somehow revive the keyboard,when i opened it up for regular cleaning every few months, but nothing i do ever fixes it. I've tried cleaning it and the motherboard connector, and the cpu and heatsink unit and fans... Not a single key responds in any way, even the fn key, and i haven't been able to use the fn +F7/8 since the F8 failed. Now,even the touchpad doesn't work correctly, i have to use atleast 3 finger for the cursor to move, and it moves very erratically because i have to use 3 fingers with a lot of force. I know this laptop is nearing its end in a few years, but for know its pretty good for most games(2 GHz AMD Athlon 64 3200+, 2 GB RAM, 100 GB HDD, 128+128MB(shared from system ram) Ati XPress 200M (overclocked from 300mhz engine clock to 375mhz), and i'm stuck with it. By the way, if you know how to overclock hp laptops like mine, please tell me,i've tried almost everything.
Thanks for showing interest in my problem, i hope we'll be able to find a solution somehow. Please remember, this is the first forum i've participated in, so i don't have much knowledge about them (pretty obvious from my HUGE post). Sorry about that. But, please help!... Thanks!
