New processor, having major issues.

post #1 of 5
Thread Starter 
Hello all, I just snagged a better processor for my laptop for cheap off eBay, but I'm having issues with it. The laptop is a HP Pavilion g4-1117dx, and it came with an AMD a4-3300m dual core clocked at 1.9 GHz. I purchased the AMD a6-3400m (which is compatible with the motherboard and all; many others have done this upgrade successfully) which is a quad core clocked at 1.4 GHz. Same socket, same thermal rating, should work just fine. Running latest bios which is F.6A from 5/2013. However, when I install it and power on, the fan runs EXTREMELY fast, and nothing comes on screen, no other sounds/indications of any sort. However, when it's installed in the socket but not locked in place, the computer sounds like it's turning on normally, but still the screen doesn't even light up or show anything. I tested my old processor; everything works as it should with that. When I place the original processor in the socket and don't lock it, nothing comes on the screen either. So it seems like it would work if I didn't have to lock it in, but I don't get display that way.

Is it defective, or is there something else I need to do? There doesn't seem to be a way to reset CMOS on this laptop, otherwise I would've tried that.

As a side question, should I go for the A8-3500m instead?

This happened to me once with an AMD chip. Might be defective, as mine turned out to be in the end... frown.gif

Then again, are you sure you plugged in everything upon reassembly? That can be a frustrating thing.

Thanks for the reply. That's very well possible, it was from a wholesale retailer on eBay and marked as refurbished.

I'm positive I reassembled correctly, since I can drop the old CPU in and all works fine.

I'm probably going to return this one and get the A8-3520m which doesn't cost much more while performing better.

I ended up getting an A8-3520M, and again, no dice. Except this one doesn't spin the fan like crazy, which is a bit encouraging. When I try booting with this one, the screen is black, the wifi light turns orange, and the caps lock light blinks once between every pause. This means "CPU not functional" according to HP's blink codes. This suggests that it has nothing to do with the BIOS at all.

Any hardware-related suggestions?

It might actually still be BIOS related. I know it's already on the most current BIOS but if you can, I would try reflashing that version and then try reinstalling the new CPU. From what I've found on the internet, it really should not be doing that, especially with two different CPU's. Or post here and see if anyone can doublecheck the microcodes in the BIOS to make sure your BIOS actually can support those CPU's:

And if it can't, they can hook you up with a modified BIOS to get it working.
