Lenovo Thinkpad T450: Laptop does not charge. No light indicator

Mon, 20 May 2024 21:54:16 -0700

The laptop does not charge, the power botton and red dot on "Thinkpad" usually blinks I plugged the charger. But now it does not do that and the laptop does not turn on. I tried removing the battery, unplugged the charger then pressing the power button for 30 seconds and plugging back the charger but it is still the same. No blinking lights, No charge, laptop does not turn on

Lenovo Thinkpad T450: No Power to Display

Sat, 11 Feb 2023 07:35:37 -0700

The computer powers on and I can hear the (very loud) chime when Windows is done loading but there’s no video on the built in display even after replacing the LCD assembly (it appeared to include the backlight board with the panel). It is usually used with an external monitor as the previous panel wasn’t working either. PC laptops are a little outside my knowledge, but I am very well-versed in Apple repairs. In Apple terms I want to reset the SMC (system management controller) but I don’t know how to do that on a Thinkpad. Does anyone know or have additional ideas? (I have tried the Microsoft troubleshooting steps for no video and they did not resolve the issue.)

Thanks!

Lenovo Thinkpad T450: How do I replace my 3.5mm headphone jack on my Lenovo T450?

Wed, 22 Jun 2022 18:42:22 -0700

Hi, I can't find any guides on how to fix the headphone jack of my laptop. I thought my headphones were dying and I decided to buy a new pair, only to have the same issue with the brand new pair I bought today. I can only hear audio out of the right side of both pairs of headphones, and I can hear from both sides on both headsets, when I hold the microphone plug into the jack. It stays, but I can then only hear out of the right side unless I move it in a weird position. Any guide/tips to this would help. Thanks.
