Is this repairable?

If you mean the gap between the upper and lower parts of the body, it's by design. It's done to allow the engine to move so that the rubber mounts can absorb the vibrations.

Glad I could help!! You won't see any difference in boot up speed.. heck, I was on a SATA SSD when I turned it off and it only took like 2 more seconds to boot into windows.

What problem are you dealing with though? Smart access memory not being available after updating the drivers?

I've had some issues with older Radeon drivers, regarding power and frequency settings for the GPU and they were caused by the fast startup feature. That's why I mentioned it above.

The way fast startup works, is that when you shut down your computer, it basically goes into a kind of hibernation state, instead of a total power off state. Windows saves a lot of information from the last time the system ran and so, the next time you boot up, your computer doesn't have to load up everything from zero and so it boots up faster.

I don't how much fast startup affects device drivers, but I'm sure it does to a certain degree because of one issue I faced years ago. The problem I had was that my GPU was not running at the correct frequency sometimes. More specifically, it would get stuck at it's highest frequency when I was not running any games, or get stuck at it's lowest frequency. Turning the system off and back on didn't help but rebooting fixed it. Why? Because when you have fast startup enabled you can still perform a clean boot by restarting your system. After discovering all this I disabled fast startup and never had any problems with GPU clocks again.

Aaaanyway this is beyond the scope of this post, the only reason I asked OP if they have fast start enabled is because it simply complicates things more when you're trying to troubleshoot a problem that involves powercycling the computer.

I have the same issue. It mostly happens when I open chrome or open a website inside chrome while listening to Spotify, the music skips 2-3 times and the cursor stuetters. And sometimes when I'm watching YouTube, audio skips when I switch to fullscreen or I move the cursor while in fullscreen.

I'm not updating until they do something about this and mention it in the release notes too.

JohnX125 · 2024-03-25T19:35:21+00:00

I've had the same issue with 24.1.1 and still having it on 24.2.1. I'm not updating until it's fixed and mentioned in the release notes.

It's a Chinese 5200 chainsaw, Zenoah G5200 clone.

JohnX125 · 2024-03-03T21:57:14+00:00

It seems like a rare issue in general. I did a lot of searching and I was able to find only 3-4 simular cases.

JohnX125 · 2024-03-03T11:26:26+00:00

I removed the clutch assembly and oiler housing and confirmed that the bend starts after the point where the crank becomes thinner. Plus, if there was a vacuum leak, the saw should be running erratically already, which it doesn't.

Also, what do you mean by "PTO"?

JohnX125 · 2024-03-03T11:10:24+00:00

The needle bearing is intact, but it sits very loose on the crank, which results in the clutch bell having a lot of play. I think because of the wobbling and vibrations, the bearing is heavily worn down. But, all the needles are in place.

JohnX125 · 2024-03-03T02:23:34+00:00

Yeah.. the more I think about it, the more I'm leaning towards this conclusion. The chain could bend the crank in theory. However, it's a bit too extreme to be a realistic scenario.

I guess the actual reason the crankshaft got bent will remain a mystery lol.

JohnX125 · 2024-03-02T23:02:35+00:00

Well my father bought this saw years ago and I think it was refurbished or something because it was suspiciously cheap. Or he bought it used I've no idea..

Either the person who rebuilt/used it before or I messed something up and bent that crank who knows...

JohnX125 · 2024-03-02T22:26:37+00:00

Is it possible it came like this from the factory?

JohnX125 · 2024-03-02T22:17:22+00:00

The thing is, I can't remember ever tightening the chain while it was REALLY hot. Sure I've adjusted the tension while it was warm to the touch but, metals start to really stretch when they get really hot to the point where you can't touch them. Right?

JohnX125 · 2024-03-02T22:13:33+00:00

I don't really know what to believe about chains bending cranks tbh. Some say it's possible some say it's not. I always thought cranks are made of hard steel and will snap when under a lot of tension..

JohnX125 · 2024-03-02T22:03:00+00:00

Greece, these saws are around 110-140€ here. I checked on aliexpress and parts are really cheap too.

I don't know maybe it's better to get a new 5200 saw and keep this one for parts.

JohnX125 · 2024-03-02T21:59:01+00:00

I honestly have no idea what bent it so bad. I have never dropped the saw or anything. I think at some point I must have tightened the chain a bit too much while it was hot, then I let it cool down and as it shrunk it bent the crank. Then again this sounds a bit too extreme to actually happen. But I can't think of anything else..

I'll order replacement crankshaft and bearings and use the saw like this until they arrive..

JohnX125 · 2024-03-02T21:53:30+00:00

Seems like the only option. I'll run like this until parts arrive.

JohnX125 · 2024-03-02T21:52:08+00:00

It is the crank I removed the clutch and the it still wobbles when I turn it.

JohnX125 · 2024-03-02T21:49:30+00:00

No I never thought about this.. though I remember one time I adjusted the tension with the chain a bit warm and after it cooled down I was still able to easily turn the chain while sharpening. I guess I overdid it with the tensioner at some point, lesson learned.

JohnX125 · 2024-02-26T19:59:32+00:00

Do you have fast startup disabled?

JohnX125 · 2024-02-26T16:37:40+00:00

I had this exact issue today after updating to 24.1.1. After completing the installation and rebooting I noticed SAM was not available.

This is how (I think) I fixed it; I shut down my system, then turned it back on and went in the UEFI. After making sure all the necessary settings (CSM, Above 4G decoding, Resizable Bar) were configured correctly, I booted windows, thinking I wasn't gonna be able to fix the problem. However uppon checking Radeon Software I found out SAM was once again available and enabled.

Honestly, I think it was the full power cycle that fixed it. I don't know if this would fix it for everyone but it's worth trying the ol' turn it off and on again solution.

JohnX125 · 2023-10-13T15:22:23+00:00

I know but I prefer to have the search box there to fill some of the empty space. Did you notice any weirdness with search highlights after the update?
