thanks for sharing. will monitor the heat for these ryzen chip.
no prob. he also mentioned overheating can damage mobo so need to be wary indeed. ryzen does outperform intel chips though, so some consolation there i guess.

Just want to share my lenovo svc support experience for those interested.

My E585 was overheating under load and sometimes BSOD, so i used online chat to contact support. I was 1st in queue and discussed with the rep, showing her screenshot of 70C temp alongside only 20% cpu usage. She said engineer will be sent and I received sms confirmation about an hour later. Appointment date was next day.

Engineer called before arriving. He was very friendly and gave frank advice. He said AMD will run hotter than intel, so may want to consider laptop fan pad if I'll be using laptop for 8+ hours a day. After warranty, I can also consider replacing the thermal grease on my own. He checked then replaced the heatsink fan assembly (easy, 4 screws and a plug), and said to call him directly if problem returns.

The entire flawless support process took less than 24 hours. I'm so glad I got their on-site 3-yr support.



Background of my overheating problem:
My 1 yr old e585 was reaching 85C while just performing backup or installing large software, sometimes resulting in BSOD. (disks temp were just 44C, 54C) A previous large windows update BSOD midway and corrupted my windows. This never happened before.

Took me a while to come to conclusion it was heat related. I ran lenovo's windows diagnostics software but fan test passed. Fortunately I found the problem after I monitored using HWMonitor. (the engineer mentioned lenovo has a temperature software for download too)

After the replacement, I ran backup and max temp immediately reduced to 75C. The old fan looked very clean and perfect, so it should be that the thermal grease lost effectiveness over time.
I have used several gen of AMD laptop, temp have not reach that high before.

AMD Turion, Phenom II and A series, highest I recall was about 70.
Average was about 50 or so.
Maybe you have to do maintenance like:
- Update BIOS (If you haven't)
- Fresh install OS/Reset OS
Especially if your OS was updated from 1809 to 1903.
Best to do a fresh install.
- Try installing the graphic driver from Lenovo than AMD.

Lenovo version maybe older but the chip will run at it's optimal
setting like clock speed.
- Update AMD Chipset Driver

i followed this link - https://support.lenovo.com/sg/en/solutions/ht103653 - to create a USB recovery disk for my T480
Thanks for the link.

I wasn’t able to select most of my USB disk as recovery during the process. Not sure the reason despite all my USB drives satisfy the requirements. Windows 10 is able to detect all of them.

Manage to create the recovery when I tried the last one.

You can try use Command prompt diskpart to partition the
USB disk suitable to create recovery media.

Yes my first instinct was check the software, so updated via vantage and windows updates. But didnt solve anything. I'm also using lenovo's graphics driver.

what's the size of your drives?
I vaguely remember i was only successful after i pop in a 16GB/32GB stick, not sure which one i popped in.

Was concurrently doing another recovery drive for my HP Envy

I'm using 32GB drive but it fails.

Resort to using a MicroSD card inserted into the USB card reader and the creation cam proceed.

Does your thumb drive have other files?

Usually I use a freshly formatted flash drive

I think it's more likely to be poor thermal paste application from the factory or sub-optimal heatsink contact. That said, my E585 ranges from 42C to 88C during normal usage at room temp of about 29C.

It's possible that the newer BIOS have changes to the CPU throttling behaviour, cos I don't remember seeing temperatures of more than 82C a few BIOS versions back.
I have ran Intel i7 8650u on Thinkpad x280 beyond 90C under full load (there is a limit to how well a slim chassis can cool).

The notebook design & thermal/power limits set by the OEM in the bios make the biggest difference.
It's not true that AMD mobile CPUs run hotter than equivalent Intel CPUs, at least for CPUs fabbed under 12nm/14nm process & set to run at similar power limits (eg: 25W).

can share what is the lenovo temperature sw ?
Just use CPU Coretemp.

Hi all,

I am using a T495. My laptop has been lagging very badly ( eg open chrome, open jpg file) it spins for quite a while, even scrolling down a web page it lags.
I even have problem shutting down.
Could it be due to the windows upgrade to V1909 (2)?thnks

Do a clean install if you know how to.

It was formatted several times right before I start the process of creating the recovery.

Yesterday, I bought another thumbdrive, same brand USB 3 and capacity, and it works out of the box.

Just curious about the reason it fails to work on the older thumbdrive despite Windows 10 detects and read/write flawlessly with it.

glad to hear that it's working for you now.
Mind sharing which brand/model thumbdrive giving you the issue?

Now bad time to buy customized laptop. Likely to take over 1 month rather than 2 weeks (as shown on website) from payment to shipping.

Sandisk Extreme USB3 32GB has the issue. But I dont really think it is faulty since Windows 10 is able to detect and I can continue to read/write files to it during my testing. Probably it is due to disk partition as someone has pointed out.

Bought 2 Sandisk Ultra 32GB with no issue out of the box.
