Intel HD graphics and ATI Radeon graphics card, blackscreen issue

[RobinOfTheRings]

Hello there !

HP g62 a80sv
Intel core i3 cpu @ 2.13
Intel (R) HD graphics
4gb RAM
ATI Mobility Radeon HD 5470 (disabled)

I was given this laptop around 5-6 years ago, informed that the ATI Mobility Radeon HD 5470 graphics card was burnt. Trusting this info, i've been using the laptop ever since with the integrated HD graphics card and so far so good. When i formated my laptop and installed new OS, i accidentally installed the drivers for the ATI card, thus activating it, resulting in a black screen while the laptop still operating just fine. Using safe mode I disabled the ATI card and switched back to Intel HD graphics. So far so good.

I 've seen that quite a few people have had this blackscreen issue with their HP G62 laptops and searching online, i found many videos that suggest a "simple" repair procedure by an (expert, of course) application of heat on the card and so on. On the other hand, i found a bios update on the Intel page reading "Fixes an issue where installing a new ATI Driver over an existing driver or uninstalling an ATI Driver causes the display panel to go black. The only recovery is to restart (reboot) the notebook."

So my question here is : What's the deal with the ATI card ? Should i go to an expert and have it checked ? Is there some way to use the BIOS update to fix the blackscreen issue ? Is there any other kind of fix out there, unbeknownst to me ?

Any help would be much appreciated.

Unless you are a computer and hardware genius, you should take it to someone who knows what they're doing.

what you are referring to is a reflow or "re-balling" as its called the ati chipset is attached with many balls of solder they can come loose.. this MAY fix it but you have to find someone with the skills to do it.. of the laptops ive done it to myself maybe 1 in 5 become operational.. your local best buy/computer shop cannot do this for you.. i have a couple advanced electrical degrees. if you know an electrical engineer most have the skills and maybe tools to do this as well as someone with an electronics degree/proficient in soldering

edit: also the reason its not always effective is the chipset/motherboard can be faulty.. in your case just the chipset itself could be faulty/burned out in which case the above will not work

re-ball at home doing fraudsters to sell under the guise of a laptop working. and some geek-freaks. in reality, this procedure for the professional with special equipment, not very cheap:
drying (recommended for drying components)
soldering system with hot air convection oven or a conveyor furnace with blowing hot air
a cup for soaking (recommended for cleaning of stencils)
soldering station (or other tool to remove the BGA balls)
protected from static workplace
microscope (recommended for testing)
deionized water
fingerstall
and high-quality re-ball with a warranty can cost up to a quarter or more of the cost of a new laptop.
