The female plug in my Compaq Presario (for AC adapter) is broken from the motherboard. Computer still runs, since the battery is about 90% charged. Cab this battery (it has 5 female terminals) be charged outside the computer, then reinstalled to run the computer? Is there a charger available for purchase that will do this? Eric

Yep, the power supply input to the laptop is gone - the external input shorted out. You may find that the Compaq repair charges almost equal a new one.

THE COMPUTER DOESN'T EXACTLY CHARGE THE BATTERY. MAYBE THE ADAPTER FOR THE C502US ISN'T COMPATIBLE WITH UR COMPUTER, OR THE ADAPTER CONNECTION AT THE COMPUTER/ MOTHERBOARD IS FAULTY.

Some laptops will not power up with a completely discharged or faulty battery. Remove the battery from the laptop, plug in the power cord and try to boot the system. If the system boots, your battery needs to be replaced. Replace your battery as soon as you can, it's not a good idea to run the laptop for extended periods with an open battery bay.

Hello,
This is true, you will not be able to charge the battery without the correct charger. For mostly all laptops, when the charger is not maintaining a charge, it is time for a new one. However, it does not have to be the manufacturer's adapter, but I recommend purchasing the battery made for the Compaq Presario M2000 Notebook.
NextTag.com has decent deals on these adapters. http://www.nextag.com/ac-adapter-compaq-presario-m2000/search-html

I hope this helps. Please let me know if you have any other questions.
Thank You, Raph30

1. The power-connector has broken-away from the motherboard. So, no power reaches the motherboard.
2. Dead motherboard.
3. Dead CPU

Good luck.

When you install a new battery and remove a battery always make sure the laptop is completely shut off and have the power cord removed so that you avoid any possible power surge.

Batteries generally don't last much longer than a year and I have found removing the power cord or battery when it is off to be a good practice.

Before you charge a battery make sure it is run most all the way down. Recharging a battery when it is not run down can give it a memory and you may only be able to charge it up to the point you started charging it.

Anyway, if the computer won't charge a new battery then you could have a bad motherboard. To be sure try another battery.

eather you have one or a couple of the following problems,

1. you have a bad battery
2. the power supply is defective
3. the charging circuit in the laptop is defective and the motherboard will require replacement or repaired.

If the battery is not charging, then the charging circuit of the motherboard is bad.

Page 3-22 lists the spare part number for the motherboard. (4 versions depending on options)

Chapter 5 covers disassembly and reassembly

dear N9YK

you can follow this

If you have a loose connection where you plug in the power on your laptop, or it works intermittently, you could have a bad dc jack. Symptoms

• Move the power plug and the laptop loses connection
• Broken or cracked dc jack
• Laptop won't charge but worked on battery
• Power LED and battery LED flicker when the adapter tip is moved
• Battery won't charge
• Sparks come out the back of the laptop

Why does this happen?

• Flaw in manufacturer designs
• Use of universal or non-original ac adapter
• Lots of plugging and unplugging of the ac adapter

• Tripping on or pulling the ac adapter cord

or you can check your dc amper in your adaptor

oke



thx

cropp

ok...try this without battery, only with ac power pack plugged in.

got backup?
