Hi,


It's more like graphic chip has gone bad.

What happens when both HDD and RAM is removed and notebook powered on?

Hi Visruth,

Thank for your help and your reply, when I remove both HDD and RAM Caps lock blinks four times (it seems that motherboard detekts that Ram memory is missing).

I also remove HDD only the issue remains (with the difference that when I hit any key on keyboard the HDD led doesn't blink) also I try to test it with (new RAM nd new HDD pulled out from a workong machine) the result is the same white screen only and nothing else .

Thank you again for your help and your response.

Friendly regards,

Jim

P.S. I also made Bios reset (bios battery is near the RAM slot so it is accessible very easy)

Hi,


It seems like graphic chip/controller issue.

Definitely a hardware issue. You've to get it checked by board level technician and confirm.

If you have integrated graphics or discrete graphics, then only solution would be to either replace processor or change motherboard. It depends on the exact model name, product number of your laptop.

Hi Visruth,

Thank you again for your help, yes that is that I was afraid from the beginning that my graphic chip is off.

The version of my G62 HP it contains intel i5 cpu and Vga ATi Radeon ith directx 11 (with seperated memory not shared) so I need to replace my motherboard or my Cpu depends from my VGA if it is integrated or discrete? right? how can I check that? 

Thank you again for your time, your help and your response!

Hi Jim,


Manual: http://h10032.www1.hp.com/ctg/Manual/c02542102

Specs: https://support.hp.com/us-en/document/c02502930

Your laptop came with i5 460M with integrated Intel HD Graphics Media Accelerator and switchable ATI Mobility Radeon HD5470 graphics of 512MB dedicated video memory�

Page 19, 20:
As I suspected, if integrated graphics is gone bad you have to just replace the processor but if dedicated ATI graphics is burned out, your only option is to get a new motherboard.

You've to get it checked by technician to decide which is burned out

Board replacement would be expensive affair. Even getting a new processor might be difficult. Nevertheless think wisely about how you should spend money and proceed. You can get better machine with that money sometimes.

Hi Visruth,

Thank you very much for your help and your respond , I will check it and I will decide if i fix it, you are absolutelly right if ati vga if burned out i will not fix it because changing the motherboard is similar to buy a new laptop in cost and other methods repairing the vga like reballing/reflow are not reliable. 

So any way thank you again for your help

Best regards,

Jim
