won't run on battery

**undergroundryan** · May 1st, 2004, 09:22 PM

I have a HP Pavilion N5470 and windows ME took a dump. So I then installed windows XP and everything works good now except it will not run off the battery anymore. It says it has a good charge, but if I unplug the ac it turns off, and will not turn back on without the ac power. Thanks for any inputs, I hope I can solve this problem.

Welcome to Windrivers underman. When you depend on software to "gauge" hardware temps or charges, you are seeing through "rose colored glasses" sort of speak. If the battery was actually working and holding a charge, it would work and keep the system on. But, also, go into Control Panel/Power Options, and make sure the XP service is running before giving up.

I'm confused....could you clarify yourself a little bit? I didn't see any XP service thing?

Like I said: Control Panel/Power Options. Then click on the UPS tab and see it the service is running.

Have you checked at www.hp.com for the battery utilities?

**FatalException0E** · May 2nd, 2004, 08:58 AM

Sounds to me like your battery is toast. Will the system start from powered off on just the battery? If so, how long does it last?

No, unfortunately without the ac power cord the laptop is currently useless. When it is plugged into ac, it recognizes when I plug and unplug the battery with the little amber battery comming on....which shortly goes back off. I do not think the battery is toast because it worked before I upgraded to XP, but I am not going to rule that out. I will check out the battery service thing and get back to you. Thanks guys, I really appreciate the help. Could I check the battery with a multi-meter?

Under control panel/power options I only see, Power Schemes, Alarms, Power Meter, Advanced and Hibernate...No UPS tab? Maybe I am missing something, but I went through all of that. Maybe I have to download extra software? BTW, I was also all over www.hp.com looking for help but have yet fixed the problem.

did you find this?

how about running the diagnostics listed here?

**freddy** · May 2nd, 2004, 11:41 AM

the obvious thing to do , is check the battery,,,,m unplug the mains lead boot it up ,,,,press f* whatever ,,and just leave it on a bios screen ,,,,or even use a win 9x 2k xp cd and boot it up ,,,and see how long the battery lasts,

sounds like you NOW have a knackered battery ,,,

repord on the above ,,,if u can eliminate the battery ,,,,then ppl can assist.

I just went through and installed all of those with no luck yet. I tried to instal the HP display utility and it failed. It said that the HPCI driver provides access to important configuration interfaces of the system BIOS...do you think this is important? All of the other ones though were all installed. The only thing that works now that didn't is some shortcut buttons above the keyboard. I really don't want to buy another battery cause I don't think that is the problem. This really sucks...

No, forgive me on that UPS advice, obviously when first posted I thought you were talking about , well, a UPS and pointed to that windows service. Just confused, sorry.
A laptop battery has the same attributes, however. And, it indeed does sound like yours has bit the dust. But, have you adjusted the setting in Bios and then within Windows, Try as Freddy says and F2 (?) into Bios and check the power settings and leave it there. You should also see a gauge there for power. You can then unplug it from within Bios to see if it stays on. What we are looking at is a probable coincidence: the upgrade to XP that is.

**undergroundryan** · May 2nd, 2004, 08:42 PM

Well, I did as freddy did and booted into the BIOS using F2. I was messing around in there...not changing any options... and did not see any options/anything about a battery. Then I crossed my fingers, reached back and unpluged the cord and goodbye BIOS. Of course it turns off...and no it would not turn back on....without plugging i back in...I have really bad luck with this ****.

No power options in Bios? I'll go check NooNoo's links, but listen. The battery no longer works!!!! OK? Just to be sure, take it to a Radio Shack to check, or some other Battery place. Down here we a place called Batteries Plus which sells even laptop batteries cheaper than the mfg. They will test the battery for you. Where do you live?
