Lenovo ThinkPad T450 Power Adapter
If buying off-brand, it is imperative to note both the voltage and amperage output. The Lenovo ThinkPad T450 AC adapter is responsible for two things, to charge any and all batteries and powering the laptop. A universal power adapter can be used if you are desperate. When purchasing a replacement AC adapter, selecting the Lenovo OEM charger is the best one to choose. Because Lenovo uses one power charger that can be used on other units, make sure you check the part number for the correct one.
Clues to watch for to know the Lenovo power adapter needs replacing
- The unit will not operate without the battery installed
- Battery does not charge at all
- Most Lenovo AC adapters get warm when plugged in for 10 minutes or more
