How to maximize the performance of HP AC Adapter:
Prevent the Memory Effect -Keep the laptop adapter healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion adapters which do not suffer from the memory effect.
Keep the laptop Adapters Clean - It's a good idea to clean dirty adapter contacts with a cotton swab and alcohol. This helps maintain a good connection between the adapter and the portable device.
Exercise the Adapter - Do not leave the adapter dormant for long periods of time. We recommend using the adapter at least once every two to three weeks. If a laptop adapter has not been used for a long period of time.
If you don't plan on using the laptop adapter for a month or more, store it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion adapters will self-discharge during storage; remember to recharge the adapters before use.
