Help on Hp G62 for video issue...
Hi, i have a Hp G62 notebook since 2010 with Win7 installed but
lately the screen shows sometimes some lines and sometimes switchs off the screen even the system is working... Sometimes appears the blue screen with some errors about video card. Now i have scanned for possibly malwares but now i think that is cleaned. What do you think? Is hardware or software issue? Need i format the system to exclude if is a software/driver issue? If is a hardware issue how can i solve it? Can you help me? -- sent from Android system phone - Rome, Italy |

Need i format the system to exclude if is a software/driver issue? If is a hardware issue how can i solve it? Can you help me? This sounds like more than one hardware issue. 1) "Lines" on the screen, can be a failure of a driver in the LCD panel hardware. Typically vertical lines of one color show up. If the lines are of other description than that, they could be caused by a failing GPU. 2) "Screen switches off" could be the power source (inverter) for the CCFL backlight. The inverter board is a narrow strip. If the screen is brownish (off-color), that could be the CCFL itself which is worn out, but your laptop isn't old enough for that to have happened. So it could be an inverter board. 3) "Errors about video card", could be a GPU problem as well. A common element to all hardware problems, is internal power distribution. The battery provides a relatively high voltage (maybe 14V or so), and switching regulator circuits make power for other systems inside the laptop. But it's unlikely though, for the inverter to be switching off because of that, because other things would likely quit first. The nearest single problem, is GPU failure. But the GPU may be integrated into the processor, so it's not like in previous generations, where an NVidia GPU had a cracked solder ball. I've never heard of a GPU failing, of the type that is inside the processor itself. It could be, that even re-seating the processor in the processor socket, may be enough to temporarily fix it. So the symptoms are very puzzling. Paul |

Still, a "thanks" would be nice :O) -- Thank you both for precious info but the notebook issued is not mine but of friend of my friend...and is located about 200 Km by me. Paul has given many importants and detailed info. I had to wait their response on issue. Meanwhile i searched on web a possible fix and most accredited fix i think that could be upgrading the video driver downloading from Hp website. The lines were horizontal and only for one time were shown. But in another case the system gave us a precise message about driver failure. Then i think that issue could concern the video driver. But now the owner has thought to take the notebook at another his friend for repairing. Anyway i'll ask him how he will have possibly fixed even the issue. I'll post here possible right way to solve the issue. Meanwhile i thank both for your patience attention. -- sent from Android system phone - Rome, Italy ----Android NewsGroup Reader---- http://www.piaohong.tk/newsgroup |
