Question Cyberpower PC Fusion Pro 2000 no longer booting

[VermilionNeko]

Hi. I'm having a problem with an old laptop. I have a Cyberpower PC laptop that I bought sometime ago now. Back in 2016, in fact. It's a Fusion Pro 2000 model apparently. Model No. W650RC. I've since given it to my sister. She mentioned she was getting a blue box appear on startup, which turned out to be a message that the CMOS battery was running low or had possibly been changed. So I opened it up and replaced the battery. I'm not sure if, in my usual clumsy nature, I accidentally knocked something, but after fiddling with it further, the laptop now no longer powers on. It did at first. It booted to the desktop. But I powered it off with the power button, tried to do something else and couldn't, and then put it back together. After that, it won't power on.

I've taken off the battery and checked it over and then re-connected it, but nada. I've checked the inside, but I can't see anything out of the ordinary. The one thing I can see, which I've highlighted, is this chip. I'm not sure what it is though, so if anyone can shed some light on it...?

I did see these two connectors:

...but I'm not sure if they were connected to anything beforehand. I can't see anything they could have been though. Perhaps they're spares...?

I've not had any reply elsewhere, but I have my suspicions that the BIOS could be corrupted. I don't know how or why though. I've tried switching out the SSD with the one from my other laptop, but there was no change. I can't replace the RAM either. So if the BIOS has been corrupted, what could I do to fix it? I've already tried removing the CMOS battery and I can't see any switch on the motherboard. Hope someone can help.

Thanks

I accidentally knocked something,
You sure you didn't knock out and power delivery component on the laptop's motherboard? If that's the case you will need to inspect the entire board for anything you might've knocked off. Then solder it back on if all you did was knock it off a soldering point. If the trace on the board was knocked out, that's a longer job. Speaking of power, did you disconnect the power from the wall as well as the battery prior to handling the innards of said laptop?

You could also try and swap the ram slot on the laptop and see if that helps. You can also remove the stick of ram entirely and see if that gives you an error beep.

The one thing I can see, which I've highlighted, is this chip. I'm not sure what it is though, so if anyone can shed some light on it...?
That's the wireless adapter which grants you WiFi and BlueTooth functionality.

If the BIOS was corrupted, you can use a CH341A BIOS programming toolkit but that would mean that you locate the BIOS chip on the motherboard and you have access to the BIOS file from the factory for your particular laptop.

Hey, thanks for the reply. I’m not sure if I did knock anything off. Nothing unusual fell to the floor when I got up or fell onto the motherboard. Looking inside and in the photo, nothing appears out of the ordinary or missing.

As to your power question - that’s a very good question. I’m not 100% sure. I may have unplugged the power pack from the laptop, but it’s possible it may have been left in. 😬 It certainly wasn’t switched off at the mains.

I’ll try removing the RAM and seeing (hearing) what happens. Thanks for the suggestion. Unfortunately I don’t have any spare RAM I can try. This one uses DDR4 whereas my other one has DDR5.

Ahhh, so that’s what that is… Thanks. 😊

Can that toolkit be easily obtained or does it need to come from the manufacturer? I’m not sure where it is on this motherboard; I’d have to examine it again.

Thanks

Would something like this be a good purchase? Or is there a specific brand/make that's recommended?

I expect I’ve complicated matters further trying to get access to the motherboard properly. I’m guessing these are ribbon connectors that need to be attached…? A couple look to have come loose and I’m not 100% on where/how they should be connected. 😕

Also, I've got a horrible feeling this thick ribbon is supposed to be connected in here...? But it's incredibly awkward and next to impossible to insert it due to how short the length of it is and being on the back cover, and the slot on the motherboard being in the middle of it. 🙁

Laptop ribbons are the worst kind of ribbon I've ever had to deal with! They're so fiddly and stubborn.

 

[VermilionNeko]

Great. Now one of the ends of a ribbon connector has come off. This connects up the keyboard, I believe. Do I need to get an exact replacement for this model/keyboard or will any do?

The lack of replies certainly isn't helping. 🙁

I'm totally lost and unsure where to go from here. I don't even know if the BIOS is the problem. The system just doesn't boot. Nothing happens when pressing the power button. I ordered myself a multimeter and I've been playing around with that a bit. I tested the power pack connector and that's fine - I'm getting 19v. I've tested the power connector to the motherboard and that's fine. I've tested the prongs for where the battery goes and I get readings. I'm not able to test the actual battery as the prongs are too thick to go inside the grill.
When it's plugged in, there's an orange power light on the motherboard, so it's getting power. Though I don't know if it's getting power everywhere it needs. I can't seem to figure out how to test the separate board for the power button though. So I'm not 100% if that's the issue...?

EDIT: Oh. And I've found a similar manual for this motherboard. There doesn't appear to be one for this exact model anywhere, which sucks, so I've gone for the closest.

EDIT 2: I'm wondering if it's the small board for the power button that's broken. The connector from the motherboard is getting a reading of around 3v. The connector on the power button board is getting no readings whatsoever. I did have to get a replacement ribbon, though it's probably not 100%; it's not the same as the ribbon I had, but from a similar model. Not sure if that's a problem...?

EDIT 3: I don't know what happened, but the light changed from orange to green and the screen came on. It came up with the message about the CMOS, but then went off and back to orange again. Odd. But surely that means the motherboard is fine...? Pressing the power button still doesn't do anything though.

So it triggers on when I use the multimeter at the connection for the screen on the motherboard:
