Laptop won't run on battery

Hey gang,
I got a used HP zt1150 laptop as a gift from a friend.

It runs fine on AC power but it will not turn on or run from the battery. The laptop will not charge the batteries either.

A guy at work has a HP zt1150. I tested my batteries on his. They work just fine! I also bought a brand new one from HP and it still will not run. Both batteries will hold a charge. The laptop will not charge the batteries and as a test, I drained one battery down to 36%, stuck it in mine and ran it under AC power. It does not charge it. It just stays at 36% on the lcd screen built into the laptop model.

I am pretty handy and can fix almost anything. I have soldered, etc.

Can I fix this myself? What is wrong? Where can I get a replacement part?

Thanks in advance for any and all help!

check the conection to the batterie

I spoke with 2 different laptop technicians that said it was probably the "charging circuit" but neither would not tell me about it, how to fix it, where to buy the part, etc. lol I know they wanted to get some business but I told them upfront I don't want to spend any money on this if I cannot do it myself.


If anyone knows where to get this part or a great source of hard to find parts for laptops...please let me know.


I checked the battery contacts and the contacts on the mobo. I took it apart and checked for broken solder connections...I did not see any. This might even be the mobo since the pc acknowledges a battery exists and shows the level of charge correctly.


Thanks in advance,

Does it still have Windows XP installed, if so does it have SP2 installed ?

I know it sounds odd but I've seen a few cases of people getting "charging circuit error" after installing SP2.
here's a compaq, http://forums1.itrc.hp.com/service/foru ... dId=683954

Hmmmmmmmmmmm interesting theory!!!!I wiped the HD clean and did a fresh install of WinXP with SP2.

I just disassembled my laptop to look for broken solders, etc and found nothing.
I will try reassembling and seeing if it resets.

I know I did run it without the battery in it but I did not set it to run on the minimum settings under MSCONFIG and I did not try booting into safemode.

Let me try it and see. I will post my findings tomorrow.

Thanks joebert for this interesting post!!!!

Hi to all

I had a HP Pavillion Laptop that was working good until I found that the battery can be not charged.

One of my friend told me this:

" I left the laptop unplugged with the battery removed all day while I was at work. Then when I came home I held the power button (still with everything removed) for 30 sec. I read this on the HP web site, it's to discharge the capacitors. Finally, I put the battery back in and plugged in the adaptor and everything worked! "

What can I do my father will make my life same as living in hell .

Why can you not re-charge the battery ?

Hi Enigma

I am happy to hear from you.

Here are the story:
My brother was working on the laptop when suddenly a massage about the battery appeared into him, then the system is off. He said that he plugged the laptop with power supply, put there was no response.

- Why can you not re-charge the battery ?

I want your help to re-charge the battery. I do not know exactly how to charge the battery because I connected the laptop to the power supply to charge the battery but the charging light was off like there was no charging process taking place.

Abdullah

I take it the rest of the Laptop functions fine, if thats so, it sounds like it might be the battery itself.

Have you got another battery or a friend with a similar battery that you could put into your Laptop & try to rechage that battery to see if it is the battery that is the problem ?

Hello

I did not try another battery, but I am going to test it tomorrow.

If there is something new I will tell you.

Thanks

Hello

I am going to test the battery, but in my way one of my friend told me that the laptop should be working without the battery just by the power supply which is not happen my case can you help me .

Abdullah

Oh right. Alot of the laptops I use connect to the mains via the battery.

It sound like either your power cord, or the connector within your laptop may be faulty then rather than your battery.

We have 2 laptops that both use the same batterys and the batterys both died a year since we had them. What my parents did was remove the batteries and put them back in and somehow that jacked up the batterys to where they only run on plugged in power sources but not a battery.

Hello

How are Enigma ?

My father knew about the Laptop. We took it for the maintenance. They said they will figure out. Moreover, they added it probably related to the mother board.

Enigma,

I would be happy to know your comment.

Thanks

I`m not sure how it could be a mobo issue, I may be wrong but this is how I see it.

Your laptop was working fine off the battery, therefore the power from the battery MUST be travelling around your mobo [ unless it gets to your components some other way ].

The problem arises when you try to recharge your battery or power your laptop using the main power supply [ both of which envolve your battery, power must travel through your battery to get to your mobo and to your components ].

Thats how I see the problem anyway.
