Re: HP DV2945SE POST failure

Thanks a lot for the suggestion!

I gave a reflow a shot (this is the second time for this laptop), and it worked like a charm!

Re: HP DV2945SE POST failure

I tested with an external display, and I didn't get an image on the laptop monitor or the external monitor.

Would a faulty GPU cause a failure to POST?

Re: HP DV2945SE POST failure

You're right, there could be a problem with the GPU. I think I've tried the external display approach before. I'll give it another go when I get home.

I don't think the GPU is the problem here, though. I would still expect an audible alert if I tried to boot without RAM, and I'm not getting that.

Hey, everyone!

I'm researching to troubleshoot my old laptop.

Model: HP DV2945SE
Motherboard markings: TIBET MB 06241-3M

[B]Current State:[/B]

When I power the unit on, the power button LED and motherboard LEDs light up. The CPU fan turns on. LCD screen does not give display. I removed RAM modules to see if I get a POST error beep. The unit does not beep.

[B]History:[/B]

I replaced the motherboard button battery, and afterward the unit wouldn't boot. I tried removing and replacing the RAM modules,...

Hi, everyone! I had an iMac that wouldn't turn on after I moved back from Hawaii, and I decided to get stubborn with it.

Apparently I'm not the only one with a dead iMac. I consider that a good thing.

Anyway, I'm in school now for nuclear engineering, and I think taking electronics repair as a hobby could be of value to me.

I've already done a few electronics fixes, but right now I'm at the stage where I look for a component that is physically damaged. It's worked surprisingly well...
