Lenovo ThinkPad T495: Laptop does not charge, clicking noise when the charger is on

Sun, 24 Aug 2025 09:52:01 -0700

Hello,

This has been happening for some time now: it started with "sometimes my laptop does not charges its battery and I hear a clicking noise" and now it simply does not charge and I can't figure out what is the problem.

I have opened the laptop to try and understand where the clicking noise is coming from, but couldn't find the origin.

Have anyone experienced something like this before?

Thank you.

Hello all,

I have a similar problem.

Lenovo T495,

Display renewed

Switched on everything great,

Then display was dark, I think I have killed by trying fuse.

Dark display, but you can recognize Lenovo's logo when starting the device

Lenovo ThinkPad T495: T495 3300U refuses to switch over to battery when unplugged

Tue, 15 Jul 2025 01:23:32 -0700

This was a headache since I got the laptop used at a pretty cheap price 2 years ago, I thought, "hey 70 bucks Canadian for a mint T495 with a dead battery? This is a simple fix!"

Anyways when plugged into a good USB c 100W PD charger, I see the laptop actually charges up the battery. Windows 11 shows the battery charging to 100% and the battery health is good.

I can see on my charger that the watts consumed thorough the USB C port goes down once the battery completes charging fully.

BUT when I unplug the laptop from USB C, the laptop shuts down completely. It refuses to use the fully charged battery.

Its not an OS issue as the device will switch off immediately when there is no OS loaded as well.

The lenovo vantage app doesnt help at all, if I remember correctly the system even correctly limits the battery charge to x% when requested in the app, so most of the battery management features still work.

When I first bought the laptop I thought "oh its just a dead battery" I bought a new 3rd party battery from Amazon, replacing the OEM battery, and the device behaves the exact same showing the same symptoms. ⏎

I've disconnected and reconnected the battery connectors, and all other motherboard connectors, cleaned the connectors out with 90% rubbing alcohol, I;ve used the "battery disable for servicing setting" in BIOS, Ive removed the CMOS battery, the main battery and USB C power and left it sitting for a week, and no change. I've reset all BIOS settings, and upgraded the BIOS and downgraded the BIOS, I've pressed that one small SMD button on the motherboard that I thought was some sort of servicing button while the power was on, while it was unplugged, while there was no sources of power connected to the mobo, no change.

I think theres some sort of switching circuitry on the mobo thats defective, besides the refusal to use the fully charged battery, the laptop performs completely fine in every other aspect.

Edit:

Ironic as soon as I posted this, I saw a post on Kijiji for a T14 Gen 1 Motherboard with the Ryzen 4650U CPU and 16gb of ram for 50 bucks, and it was a perfect drop in replacement :)

Had to wait 2 years for it lol

I am going to repurpose the 3300U T495 motherboard as a Desktop mini PC since the battery circuit is flawed

Lenovo ThinkPad T495: Installing WWAN card on WiFi (only) T495

Mon, 03 Oct 2022 07:51:10 -0700

I got a T495 for work, but it didn’t come preconfigured with cell connection. I opened up the bottom case and saw that it has the SIM port soldered to the board. Would I be able to install LENOVO’s WWAN card and antennas and be able to use the cellular connection? Or is this BIOS locked to not accept the WWAN connection?

It worked just fine and still turning on. After i want to charge my laptop, the led just blinking and not charging. Both usb c is not detecting the power and not recognizing a phone(not trying a usb c drive cause i dont have it). I tried diagnosing but no issue. And im afraid it’ll turn off completely
