HP NC8000 Power / Battery Problem

Hi Guys,

Got a NC8000 Laptop that runs fine on ac power, will run off battery (currently a 18%) but wont charge.  I pull the battery and power out, then put the ac power back and the charging light comes on for a moment then goes away.

Same when I take power off and pull battery out, then put just the battery back, it blinks for a second then goes away.  Have tried different charger, the result is the same.

Ive got a friend with a similar model and will borrow their battery in the next couple of days to rule out a dud battery........

Otherwise, I guess I am right to conclude that its the power charging circuit.  Is this built on to the mother board on this model laptop.....

Is it repairable ??? (without replacing the entire motherboard).  I love the laptop........i get 4 - 5 hours on wireless out of the battery normally, but It might be better to just cut my losses and buy a new one.....

Any advise ideas ?

Are you saying the charging circuit is integrated into the motherboard on this model.......

I have been informed some laptops are not......

This might be the more historic laptops though.....

I havent pulled apart the laptop, and the service manual does not say..

Im not showing a charger board as being an available replacement part, which usually indicates its integrated onto the motherboard.

>> Typically a laptop battery will last 2 or 3 years.
>> (They will 'get old' in about the same amount of time even if not used due to chemical breakdown.)
>> - So if you do get a new battery get a NEW new one.
>> One that's been on a shelf somewhere for two years might not last very long.

Got no problems spending the money getting a brand new battery.....just need to make sure it is definately the battery.


>> Laptop batteries aren't just battery packs.
>> They have circuits inside that have to do with monitoring battery condition and charging.
>> The blinking light you see is (for lack of better words) the system 'talking' to the battery.
>> (Checking condition/status.)

Yer i know, the HP battery condition program doesnt work on my model tho.....


>> Odds are you just need a new battery.

Im hoping so.......will find out tomorrow morning when the person with a nc6000 comes in......

anxious wait tho....  I can run it on battery most of the time.....but its just such a hinderance and defeats the purpose of a laptop.

Cheers for putting my mind at a little ease.....will let you know how it goes.......

just thought i would let you know, pulled a battery from a NC6000.  It worked in my laptop (had to pull the clip off for it to fit), i was also able to charge it.  Then once I stuck my old battery in it started to charge ?!?

I have read about this in forums elsewhere, but it was only concerning Toshibas.

So.......I will purchase a new battery regardless........

Thanks guys....
