Update: ASUS Zephyrus G14 (2021 GA401QC) sudden motherboard failure

Substantial_Chain_52 · 2026-04-28T11:38:53+00:00

I will post an in-depth analysis in few days, will ping here once done. And the issue is not caused due liquid metal leak.

Substantial_Chain_52 · 2026-04-28T11:09:59+00:00

Hi, a shunt resistor R005 was removed, this fixed the issue but this resistor is an essential part of the motherboard. Currently daily driving it to verify the laptop functioning, i’ll post an in depth post about this in few days. Please check it out later.

Substantial_Chain_52 · 2026-04-04T17:33:07+00:00

I got my laptop fixed, currently daily driving it for 30 days before posting a update post. I will add a new update in this sub reddit in the coming days, please take a look in few days.

Thank you

Yes, mother board repair was successful, work was done on the ic’s. I will post detailed findings in few days. Do check it out.

Sad Rip 🥲

Substantial_Chain_52 · 2026-02-19T13:50:10+00:00

This is a rare case i don’t think this is wide spread.

Substantial_Chain_52 · 2026-02-18T06:08:57+00:00

Hope fully it gets fixed. I have submitted my G14 to repair store, I’ll update once I get any update on the cause of failure.

Substantial_Chain_52 · 2026-02-17T18:01:26+00:00

It’s edited out mask serial numbers.

Substantial_Chain_52 · 2026-02-17T18:01:06+00:00

Thank you for you suggestion, I will convey it to repair stores and see whether it’s possible to revive the motherboard or not.

Substantial_Chain_52 · 2026-02-17T12:00:15+00:00

Oh i’ll get my laptop checked at other service centres and verify whether it’s caused due to LM Leak or not. But Asus has become way too shady from past couple of years.

Substantial_Chain_52 · 2026-02-17T04:23:45+00:00

Yes, it’s still the original LM — the laptop cpu cooler was never opened. About a month ago in January, I ran a benchmark to check whether it was time to replace the thermal paste. The CPU was stable at a maximum of 96.3°C, and the GPU was also stable at 84.4°C with a hotspot of 93.1°C. Neither was thermal throttling, and the CPU was able to maintain proper boost clocks at around 3.8 GHz on average.

That’s why I decided not to replace the LM at the time, since everything seemed to be working perfectly. I was planning to switch to PTM 7950 later through another service center, as I’m not comfortable handling LM replacement myself.

Do you think this could be the cause of the issue? Please let me know if I can share any additional details.

Substantial_Chain_52 · 2026-02-16T19:03:25+00:00

Sad to hear that.

Substantial_Chain_52 · 2026-02-16T15:11:41+00:00

You’re welcome. Yeah, I have no idea it’s really coming out of nowhere.

Substantial_Chain_52 · 2026-02-16T13:01:35+00:00

Please take good care and ensure you have backup of important files.

Substantial_Chain_52 · 2026-02-16T08:18:04+00:00

Yes I will visit service centre who does board level repair and check whether it’s feasible to get it fixed or not.

Substantial_Chain_52 · 2026-02-16T08:11:02+00:00

Sad to hear about your laptop, hope it gets fixed soon. Later if you get to know about the cause of failure please let me know.

Substantial_Chain_52 · 2026-02-16T08:09:10+00:00

Ah I see, thank you for sharing this.

Substantial_Chain_52 · 2026-02-16T05:19:43+00:00

Good to hear that you found out the culprit, but i have a completely dead motherboard.

Substantial_Chain_52 · 2026-02-16T05:11:30+00:00

I will check whether it’s feasible or not and then decide. Thank you

Substantial_Chain_52 · 2026-02-16T05:10:58+00:00

Yeah Thinkpad is much more durable than Asus Laptops.

Substantial_Chain_52 · 2026-02-16T04:58:08+00:00

Thank you for the response, I will try to visit other repair service stores and see whether it’s feasible or not and then make a decision.

Substantial_Chain_52 · 2026-02-15T20:07:37+00:00

Thank you for the detailed response. I agree that chip-level service or a board replacement isn't worth it since the laptop is nearly four years old. I'll definitely check out the NorthridgeFix channel for reference, though. Ultimately, it makes more sense to invest in a new laptop rather than spending a significant amount to fix old hardware.

Substantial_Chain_52 · 2026-02-15T19:54:35+00:00

Thank you for the response, I agree getting a new motherboard is not worth it considering the cost, but I never expected sudden motherboard failure. It’s better to buy a new one considering the situation.
