Question about Compaq Presario R3000 Notebook

1 Answer

Battery won't charge

I have a Compaq R3000 that is typically plugged in to the AC adapter, but occasionally I run it off the battery. A couple of weeks ago when I unplugged the AC adapter the computer immediately died, as if the battery had no charge. I ordered a replacement battery, but this one behaves the same. When I check the power monitor the battery appears to be stuck at 0% or 1%, even when it has charged over night. The charge light is on when the computer is plugged in, but it appears to go out after 30 minutes or so. The computer runs fine on AC power, but dies immediately if unplugged. Any thoughts?

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

Compaq R3000 new battery but does not work


Make sure you have the right AC Adapter hooked up to charge the battery with.

If you do then its a problem with the motherboard. If your using an offbrand ac adapter then that could be the culprit.

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.

Battery won't charge


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

My Compaq R3000 does not charge up


The problem might be the battery itself. Four years is a long time for rechargeables. Also, check if the error ocurs when the battery is not in the slot.
