Sony PCG-TR Power Adapter
Due to the fact that one Sony adapter powers multiple other machines, be certain you select the correct one for the PCG-TR model. If you decide to buy an non-Sony adapter, it is imperative to note both the voltage and amperage output. A universal power adapter can be used if you absolutely need to. The Sony PCG-TR AC adapter is needed for two reasons, to charge the onboard battery while simultaneously providing power for the laptop. When purchasing a replacement charger, selecting the Sony OEM charger is always going to be the safest and easiest way to go.
Subtle hints the power charger is dead
- The laptop does not run while solely using the AC adapter
- Battery does not charge up every time
- Most Sony AC adapters can get quite warm when they are plugged in for a period of time
