the power system has been interfered with,i won't use a complicated language but i need you to try and use an adapter,if it doesn't work it means the transformer has a problem or it has failed completely and it needs replacement
If the rechargeable battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.Since you did not supply details of your device and the type of battery I cannot advise where to purchase the battery. I suggest you Google the Internet for the rechargeable battery you require.
After a while even rechargeable batteries loose the ability to hold a charge. This process accelerates when the battery is allowed to lie completely discharged for long periods of time. NiCad batteries especially have this issue. If you left the battery sitting for long periods without occasionally charging it, it losses the ability to hold a charge. It appears you are going to have to either do without the battery or replace the pack. I would take out the old one, it will eventually start to corrode and leak and if its still in your machine it will cause damage.
If you get a new battery pack make sure you charge it fully and then depleat it completely before recharging it.
hope this helps.
