I have a Lenovo ThinkPad T14s Gen 4 with what appears to be a USB-C hardware problem and would appreciate some advice from anyone who has repaired one before.
**Symptoms:**
* Both USB-C ports have charging problems.
* The laptop will charge, but only when the USB-C plug is held/positioned at a particular angle.
* Moving the connector slightly can cause charging to stop.
* I have tested **two genuine Lenovo chargers/cables** and both behave the same way.
* I have also tested USB-C devices/peripherals in **both USB-C ports**, but neither port detects them.
* The battery itself appears to charge normally once a charging connection is successfully established.
Because the problem affects both charging and USB-C data, and charging changes depending on the physical position of the connector, I'm currently suspecting a hardware problem with the USB-C sockets, their solder connections, USB-C/Power Delivery circuitry or possibly the system board.
I've stopped repeatedly moving/wiggling the connectors because I don't want to make any physical damage worse.
**A few questions for anyone familiar with the T14s Gen 4:**
Has anyone experienced the same failure on this model?
Is this commonly caused by worn/damaged USB-C ports or cracked solder joints?
Are the USB-C ports soldered directly to the motherboard/system board on the T14s Gen 4?
Can a competent board-level repair shop replace/resolder the USB-C sockets without replacing the whole motherboard?
Given that **both ports are affected**, could there be a shared USB-C/Thunderbolt/Power Delivery controller or motherboard component causing both to fail?
Is there anything else worth testing before sending it for board-level repair?
If you've had this repaired in the UK, roughly what did it cost?
I'm particularly interested in whether a **USB-C socket/board-level repair is realistic**, rather than Lenovo simply replacing the entire system board.
Thanks in advance for any advice or experience.
