Re: 8930g lcd bklt issue
Hi jasko_jacker
I have an 8920g that was almost destroyed and I changed with patience GPU chip (reball), NEC Tokin, GPU pipe strangled by another thecnician and 19v DC intake cable welding
But I did not knew the backlight problem of these units and is the only thing that remains unresolved
Like more people I discovered that pressing Fn + F6 several times the backlight keeps on when CCFL reaches working temp. Also discovered that using a 120 watt DC adapter the problem reduces a lot even desapearing when bright is at...

Re: About DM4-1155 and ATI 216-0774009
I dont know answers to your "what about" but I know that if there were more laptops with dual graphics working without chip ATI could be an easy and convenient way to repair themLeave a comment:

Works ALL of it.
ALL other drivers can installate ok and a new clean installation of Win7x64 run free of problems.Leave a comment:

Re: About DM4-1155 and ATI 216-0774009
It works I swear
The ATI chip doesn't even appear of course in the hardware administrator. I can't guarantee the same procedure works in some other machine with dual graphics but for reballers could be a good idea creating a list of machines tested for it.Leave a comment:

Re: About HP DM4-1155 and ATI 216-0774009
Yes, the CPU was totally cleaned and applied Arctic MX4. For the GPU I applied a thermal pad of 7 w/mk (you know, the white one). The fan turns ok, totally loose, the axis is in perfect condition and of course the motor works.
I'll enter the motherboard in the reballing machine today.
My doubt aobut buy a new chip or try it wihout any chip persists.Leave a comment:

About DM4-1155 and ATI 216-0774009
Hello
I have on my hands a Pavilion dm4-1155 with an i5 and graphics ati5450 chip 216-0774009
It overheat a lot. I have try all even disabling ati in windows but none seems to resolve the issue.
Of course like most of the devices with a switchable GPU a have installed drives from HP to make right the switching
It have not reballed yet (I know because in this case the DM4 is mine)
I really can live without the Ati GPU and leave only the intel, that's I'm gonna extract the GPU 216-0774009 and try the DM4 without the chip.

Re: New Members - please post your introductions here
Hello.
We are an IT service from Spain.
We make reballing and are also programmers starting from a single ZX Spectrum years ago
To be modest, I know about IT from the little electron to the high level programming languages. Or at least want to know
Are pleased to be hereLeave a comment:
