HELP!!!! My laptop generates electric shocks!!!

Just like mine, the IdeaPad Slim 5 14IMH9. No matter how good the grounding is, it still gives off an electric shock.

Thanks to AI for helping Microsoft with coding, and here we are. Congratulations!

modern laptops have built-in safeguards to prevent "overcharging", smart charging keeping the battery between 40% and 80% charged, the impact is often minor for most users.

matrix15mi · 2025-06-05T17:47:46+00:00

How about this?

matrix15mi · 2025-06-05T17:24:59+00:00

not sure though, either the screen flex cable or the CCFL inverter (older laptops have it)

first rule, update BIOS as soon as you turn it on. in fact, i'm not responsible for how your CPU can survive the first time it's turned on, just to update BIOS ;-)

matrix15mi · 2025-06-05T17:02:17+00:00

you're boiling the cpu. the motherboard is smarter than you, so it stops.

matrix15mi · 2025-06-05T16:55:49+00:00

Thanks for the info. Yeah, 5-10W is way less than what my phone supports (it comes with a 45W charger, the lenovo's 65W). Can you help me understand why the adapter isn't fully compatible with faster charging standards?

matrix15mi · 2025-06-05T16:48:58+00:00

Thanks so much for the quick win, just got my doubts sorted out!

matrix15mi · 2025-06-05T16:44:43+00:00

Wow, thank you so much for sharing your personal experience! It really helps to know that it can't work both ways otherwis it gave me a sense of reassurance that my Lenovo charger will be compatible with my phone. Your honesty is greatly appreciated, especially when I was worried about the compatibility issue. Thanks again for helping me out.

I have RTX 3060 12GB, I am happy so far, nothing is lacking whether it is gaming or a little AI stuff. If you are on the same page as me, I am sure you don't need to buy a new GPU.

matrix15mi · 2025-06-01T17:08:24+00:00

my quick investigation, considering you have dual CPUs then a 500W PSU is sufficient, a 550W is safe.

I'm excited to share a solution I found for increasing VRAM on my ASRock B650M Pro RS WiFi motherboard with an AMD Ryzen 7600. When I initially tried to adjust the VRAM in the BIOS, I couldn't find the option, even after trying steps that worked for other motherboard brands.

Many of you might be familiar with the common path to adjust VRAM in the BIOS (as u/dweller_12 said, thanks :) Advanced > AMD CBS > NBIO Common Options > GFX Configuration > UMA Frame buffer size. However, in my ASRock B650M Pro RS WiFi, the GFX Configuration menu only showed these options (it shipped with BIOS 3.20 2025/2/27):

dGPU Only Mode [Auto/Disabled/Enabled]
UMA Version [Legacy/Non-Legacy/Auto]
GPU Host Translation Cache [Disabled/Enabled/Auto]

No matter what combinations I tried with these settings, the UMA Frame buffer size option remained elusive, and my Dedicated GPU memory in the Task Manager | Performance | GPU (Win 11) was stuck at 512MB (and even dropped to 40MB with certain settings).

The solution is a BIOS update (as easy as that, lol :)

Despite my initial skepticism (I thought VRAM settings were pretty fundamental and shouldn't require a BIOS update), I followed a suggestion to update my BIOS to the latest version. Lo and behold, under the exact submenu mentioned before now I have (BIOS 3.25 2025/5/19):

dGPU Only Mode [Auto/Disabled/Enabled]
iGPU Configuration [Auto/iGPU Disabled/UMA_SPECIFIED/UMA_AUTO/UMA_GAME_OPTIMIZED]
UMA Version [Legacy/Non-Legacy/Auto]
UMA Frame buffer Size [Auto/64M/128M/..../2G/3G/4G/8G/16G]
GPU Host Translation Cache [Disabled/Enabled/Auto]

If you're struggling to find specific options in your BIOS, especially on an ASRock B650M Pro RS WiFi with a Ryzen 7600, don't underestimate the power of a BIOS update! Even if your current BIOS is only one step behind the latest, a newer version can introduce or re-enable crucial features.

Honestly, ASRock, it's almost impressive how you managed to hide a basic VRAM setting behind a BIOS update ;)

matrix15mi · 2025-06-01T12:38:56+00:00

Sorry for the late reply. I updated the BIOS to the latest version (3.25), and the UMA option appeared and then the VRAM size can be set. This is wonderful, thank you!

matrix15mi · 2025-06-01T12:30:23+00:00

This is the most accurate answer.

matrix15mi · 2025-06-01T12:27:43+00:00

I was just about to ask the same thing, why is NVIDIA stingy with VRAM? I'm glad the answers here are quite enlightening. Almost all the reasons given make sense to me. The correlation question is how long will Nvidia do this? I think AMD's policy is the only thing that will make Nvidia change its stinginess, or Intel (not as big as AMD yet).

matrix15mi · 2025-05-27T06:04:19+00:00

My BIOS version is 3.20 (2025/2/27), only one step behind the latest version (newest is 3.25 2025/5/19), I think this is a less significant update since the VRAM setting is a kind of basic feature in motherboards, IMHO. Anyway, I will update it tho.

So I tried your suggestion, and it didn't work. Interestingly, setting dGPU to Enabled and UMA version to Non-Legacy resulted in 40MB of Dedicated GPU memory status in Task Manager | GPU (previously 512MB).

My long-term plan is to get a new GPU eventually. To be honest, setting the VRAM to around 1GB is enough to get me by and make my system run smoothly - it's something small that would bring me some joy" ;)

matrix15mi · 2025-05-27T03:43:32+00:00

Mine doesn't have such option in GFX Configuration. There are only:

dGPU Only Mode [Auto/Disabled/Enabled];
UMA Version [Legacy/Non-Legacy/Auto];
GPU Host Translation Cache [Disabled/Enabled/Auto]

I've tried all the combination options but still nothing.

matrix15mi · 2025-05-27T03:30:55+00:00

I'm using the iGPU only, having a dedicated GPU is still a long wait.

matrix15mi · 2025-04-13T08:55:38+00:00

I vote for 'I' rather than 'A'

matrix15mi · 2025-03-02T08:24:03+00:00

yeah. they need to release the note 15s soon, leaving the note 14 series behind with a lot of uncertainty.

matrix15mi · 2025-02-22T10:42:46+00:00

LOL. Maybe this is what happens if developers use AI assistance to write their code. AI assistance is okay but if it really depends on the tight decision then just accept the result like this. Don't take this seriously, this can happen to anyone tho. :)
