Name three common power supply issues in laptops.
***Not holding charge
***Leaking
***Overheating
Additional information is below:
***Check the power LED:
Check the power light on the AC adapter, if this if off the laptop won’t get power and battery won’t charge.
***Check Connections: Verify that the laptop is firmly connected to the AC adapter and that the AC adapter is firmly connected to the AC outlet.
***Make sure you are using the right power adapter.
***Check the battery and voltage: Make sure battery is fully inserted into battery compartment. Lastly, test the batteries voltage - They have a shelf life and can only be recharged for so many cycles before failure.

There are two different types of twisted-pair:
Shielded twisted-pair (STP) and unshielded twisted-pair (UTP).
Additional Information:
Both types of cable have two or four pairs of twisted wires going through them. The difference is that STP has an extra layer of braided foil shielding surrounding the wires to decrease electrical interference. UTP has a PVC or plenum coating but no foil shield to protect it from interference.
