SOURCE: battery or ac adapter problems?

The power jack on the system board may be loose or disconnect. The only way to check it is to plug in the AC adapter and wiggle the connector , if it feels loose then that is the problem. The other way to find out, is taking out the motherboard and checking it.

The fact that the battery was charged when you receive it tells me that the seller knew about the problem. He probably held the adapter plug in such a way that the battery got charged.

Worked off the battery but it wont charge or run off power cord adaptor


Check and make sure the power adapter doesn't have a fuse somewhere in it. Then chk the wattage output of the adapter. Watts should be marked on the adapter.. Now see what the computer requires. Computer info is on the sticker on underside of computer.To determine how many watts the computer needs, Note the amps the computer draws(on label) and multiply the volts(on computer again) x the amps. Answer will be your needed wattage.
Use only the adapter that came with the computer. They may look alike, but there is a difference. Make sure the computer is powered off. A full charge is needed now since the battery was dead. Allow time and don't use the machine prematurely.
Make sure the adapter output matches or betters the requirements of the computer.- Good Luck-Ned

Laptop Battery Won T Charge on a laptop dell inspiron 1525


Battery could be dead and won't hold another charge. Batteries only last for so long until you have to replace them. If you laptop is ok with the AC Adapter & Power Cord meaning it boots and allows you to work in windows, then the battery is definitely dead.

Acer Aspire 5610Z dead battery & malfunctioning power adapter


But before you buy a new battery, You need to again repair the power plug where your adaptor's plug is inserted so that it will not create any problem later. There might be loose connection or sort wiring.. Good luck..

Will the aspire 5735 start up with a dead battery


A dead battery will usually stop a laptop from starting up. Remove the battery and try running from the power adaptor alone. If this works you can be sure the battery is dead.

Dell 1525 won't run on ac but will on generic battery


Dell systems will not charge the battery without a Dell Branded AC adapter connected to the system (The BIOS looks for the adapter ID and disables the battery charger if not ID'd)
It appears, that since the system will not power on with either AC adapter, that there is a problem with the power connection of the system. You can replace the power board

if that fails to resolve next is the motherboard

Laptop is not switching on..no leds turning on ..dead!


There could be a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.

If this did not work, try also disassembling the laptop & make sure that all main components are seated properly. Also make sure that all ribbon cables interconnecting the various components of the laptop are tightly connected.
