Laptop problem (HP nx5000)

[Cajun]

Okay i have an HP nx5000 laptop about 18 months old (only came with 1 year warrenty) 1.5 intel centrino, 512megs ram cdrw/dvdrom

Problem i have having is the battery is not charging. First tried my battery in another laptop fine, there battery in my laptop(does not charge). Tried different power cords, no change

It has two replacement system boards(HP have said this is the only part that has anything to do with charging), and a replacement cpu.

Either of these fixed the problem.

Anyone got any other idea what could do.

Has your electricity been cut off?

i GOT A BIT CONfused reading that one but from waht it seems you have a dead mainboard.. mabey fuse blown in it? Is your powercord really twisted? You get internal wire breakages that could have changed resistance of the electricity coming in to the laptop and then changed the amount of amps... then that pops a mainboard fuse according to the hardware techhie for laptops here at work.

I'll think of some other possible problem after I take a dump.

Batterys are classed as consumable items as they deteroiate over time.

The laptops we sell come with a 3 year warrenty but the battery only has a 1 year warrenty anyway due to that fact.

the reason the battery deteroiates is because people run it of the ac power all the time, hence trickle charging the battery and never actually letting it run flat then chanrging it all the time. then they expect it just work when they need it, despite the abuse.

If the battery isnt detected at all (battery light/charge light) doesnt come on then thats either a faulty mainboard or a connection problem.

My solution: BUY A TOSHIBA

So does the laptop run ok on power only?

[The_Dover]

Have you checked the kill switch? Has it got gas in it?

Has it got gas in it?

Or maybe you just need to flick it to reserve Dover.

IT IS NOT A POWER, OR BATTERY PROBLEM

Hmmmm Power is pluged in

This as been taken over past 2 weeks

In pasted two weeks hp local dealer as put two different(new) system boards in, since this is what hp told them was the only part that as only thing to do with charging(or so they say).

Also tried replacing the cpu, just on an off chance that might work.

PS - my work does ibm desktops and hp laptops, so i have no choice in what i get

[N4CR]

Yeah what wasp said. We have an in house portables plus techie.. and we are only tosshiba too. 1 year warranty is fair enough but they should have some massive sticker explaining not to rape batteries. Sigh.

there battery in my laptop(does not charge). Tried different power cords, no change

Ahh... it is a power problem on your mainboard not the powerpack itself. A fuse has most probably blown and I have seen this behaviour before about 3-4 times myself.

[Wasp]

not to rape batteries.
I rape my battery :o when the time comes that I need it to actually be portable and not a desktop ill just grab one of the many spares on the shelves here.... :shifty:

Interesting Cajun, more often than not changing the mainboard fixes alot of things with laptops, if its not the mainboard or cpu then what else is it???..... THE BATTERY!.....

most toshs have power pcbs that plug into the mainboard - ive seen a few faulty ones before so its not impossible.


IT IS NOT A POWER, OR BATTERY PROBLEM
Are you trying to tell me its a user fault?? :bleh: :rofl: :bleh: :rofl: :bleh: :rofl:

Based on many years of bitter personal experience, laptops are crap. You can guarantee that they'll fail when you really need them to do what they are supposed to -- provide self-contained and remote computing power. And they are largely status symbols rather than sensible or credible business tools. But if you want to look cool at the airport and enjoy fannying around with touchpad mouses or those stupid green sticks that protrude from the keyboard, and enjoy typing on a non-ergonomic keyboard, then buy one.

Oh God - there's a spare Dover? I thought one was enough

[Cajun]

Have you guys read what i said. I am a system admin for one of largest ports in the country, and been working hands on with computers for excess of 15 years.

I was hopeing someone would have something insiteful which might helpful was one thing by wasp, but with the system board being replace, already voided is comment(thanks anyway man)

NEW BATTERYS DO NOT CHARGE IN THIS SYSTEM
MY CURRENT BATTERY CHARGES IN OTHER LAPTOPS

[The_Dover]

Maybe you need to drill some holes in the battery like Cibby did?

Problem i have having is the battery is not charging. First tried my battery in another laptop fine, there battery in my laptop(does not charge). Tried different power cords, no change

Does the laptop run at all ? if it does it won't be the cables fault ... unless the voltage/current from the adapter was too low I suppose...


It has two replacement system boards(HP have said this is the only part that has anything to do with charging), and a replacement cpu.

Either of these fixed the problem.

... did you mean neither ?
Once the battery is charged can the laptop run from it ?
Is the correct battey level shown in the laptop ?

I would check all the cables/wiring between the power plug and the battery. Follow the path the power takes to the battery. I wouldn't be surprised if there was a second path that connects the battery almost directly to the power socket.

of course this requires a bit of time/dissection but its out of warranty isn't it :(

Make sure you have some reasonable jewellers screwdrivers (I got a great stanley set from DSE for $10-$15) http://www.dse.co.nz/cgi-bin/dse.storefront/44b72b6f09aaaf1e273fc0a87f990718/Product/View/T4381

service manual should be in here some where:

FFS. This is going to be my last post in here probably.

We have had computers blowing multiple mainboards because the power adaptor is fucked BUT STILL WORKING MOST OF THE TIME WITHIN TOLERANCES. THE POWER ADAPTOR BLOWS THE FUSES ON THE MAINBOARD DEPENDING ON HOW TWISTED THE WIRES AND HOW MUCH CURRENT GOES THROUGH THE COMPUTER WHEN IT IS PLUGGED IN, RESISTANCE CHANGES SO CURRENT DOES ALSO (DUE TO TWISTED/FRAYED WIRES IN PSU BUT IT STILL GOES). YOU REPLACE THE MAINBOARD THEN GIVE IT BACK AND IT COMES BACK SAME PROBLEM, LOOK AT THE POWER ADAPTOR AND IT HAS TWISTED/FRAYED WIRES. OR ELSE YOU HAVE A SHORTING PROBLEM UNDER THE MAINBOARD BUT THEY WOULD HAVE PICKED UP THE BURN MARKS ETC WITH SERVICING/REPLACEMENT.

IF YOUR BATTERY STILL WORKS IN OTHER COMPUTERS IT CAN BE DISCOUNTED, SAME WITH THE POWER SUPPLY (BUT WITHIN REASON APPLIED ABOVE). SO OTHER THAN THAT WHAT ELSE CAN CAUSE YOUR COMPTUER TO STOP POWER FLOW? FUSES ON THE MAINBOARD OR LOOSE CONNECTIONS, PICK ONE I'M GOING FUSES.

THE REASON ANOTHER PSU DOES NOT FIX THE PROBLEM IS THAT FUSES ARE ALREADY BLOWN BY THE USUAL ONE YOU WOULD HAVE PLUGGED IN FIRST TIME YOU GOT IT BACK. GET WHERE I AM COMING FROM? MAINBOARD #3 FOR YOU DEAR SIR.

"since this is what hp told them was the only part that as only thing to do with charging(or so they say)." THAT CONFIRMS MY ARGUEMENT. TAKE THIS TO THEM AND PRINT IT OUT OR SOMETHING. POWER SUPPLY IS WORKING BUT CAUSING THE MAINBOARD TO BLOW ITS FUSES.

On a different note, despite the manufacturer giving only a one year warranty you may still be covered. This is fact under the consumer guarantees act, that at a fair price (ie market price) a good should be expected to last a reasonable time (ie longer than one yr!). An appliance company got taken to task after a product (washing machine in this case) failed around 6 months after the one year warranty expired. It was deemed that the product was not up to spec as it should've lasted at least 5yrs, and the company had to repair the faulty product, despite the warranty being expired.
