Sony VGN-SR540G Power Adapter
The Sony VGN-SR540G power adapter provides two functions, to charge the onboard battery while simultaneously providing power for the laptop. If buying off-brand, it is imperative to note both the voltage and amperage output. When purchasing a replacement AC adapter, selecting the Sony OEM charger is the best one to choose. A universal AC adapter can be used if you absolutely need to. Due to the fact that one Sony adapter is most likely used on other laptop models, double-check the part number or model number of the adapter.
Major indications your laptop charger is failing
- The unit will not work while just using AC power
- Your Sony battery refuses to charge all the time
- Most Sony adapters can get quite warm when plugged in for any length of time
