dv9000t power issues? Maybe?

OK, I'll admit I'm a little trigger-happy after my false start with the dv9000t (overheating/shutdown issues on first one; exchanged for new). I've been using my replacement for about a week now, exclusively on AC power, with the battery plugged in. It's been fine, but last night I went to turn it on, and nothing. I plugged in the AC, and the blue LED light around the power jack lit up, but it wouldn't power on. I then unplugged the AC, removed the battery, reinstalled it, plugged the power back in, and it powered up fine, and was OK the rest of the night.

I called HP, and they told me to remove the battery, unplug the AC, and press and hold the power button for 30 seconds to 1 minute to drain the capacitors. She also sent me a link to a BIOS update, but this appears to be the version that I'm already running (I'll try to run the "update" anyway). My question is, could this be from running the thing on AC all the time with the battery installed? Is it better to run from the battery and only on AC when necessary? I've run it on the battery a couple of times, mostly just for the fun of it, so it has never dropped below 96% capacity. Should I let it drain down and fully recharge a couple of times? I read that someone with a dv8000t had the identical problem, but I never saw the resolution.

Any thoughts?

 

I have this same issue with my dv9000z. See my post on it:

Update - It did start up that day after I removed the battery and plugged the charger in. After it started up I put the battery back in and unplugged the charger. Unlike you, I use it a lot on just battery power. The next day it started up just fine. The day after that it wouldn't start up again (no lights, etc). It seems to not want to power up every couple of days unless I take the battery out. It's annoying but I haven't called hp yet.

 

For what it's worth, I'll tell you what they told me to do:

1. Disconnect the AC adapter.
2. Remove the battery.
3. Press and hold the power button for 30 seconds to 1 minute.
4. Reinstall the battery.
5. Reconnect the AC adapter.
6. Download and install the latest BIOS version for your model.

I haven't done any of that yet, but I know the BIOS version she referred me to is the same version I have now. I saw another, more recent version floating around on the FTP site she gave me, but I'm nervous about trying to install it without their "permission," and without knowing for certain that it's for the dv9000t.

At any rate, thanks for the info.

 

Thanks for sharing the info you got from hp. I'll try the first 5 steps later tonight but I'm kind of nervous about updating the bios too, especially without calling hp myself.

 

I actually have the same problem with my dv9000z, but I didn't call HP about it. Also, the battery life without the AC is NOTHING compared to my old
dv8000t. I wish my dv8000t didn't have a sucky keyboard, because I liked it so much better!!! The screen also sucks compared to the dv8000t, in my opinion.

 

Howdy..

I've also experienced this issue with the dv9000t. Just happened for the first time today.

Best,

Benjamin

I hope I'm not breaking some sort of rule or anything, but for what it's worth, here's the link to the latest BIOS update for the dv9000t. Note that this is for the Intel version only! I installed this and have had no troubles since: ftp://ftp.hp.com/pub/softpaq/sp33501-34000/sp33832.exe

 

Good info to know.

Mine has been very stable since I've had it (about 3 weeks now).

I have a 6 year old compaq 1800 that did that every so often (and yes, we are still using it ). We updated the bios and never saw the problem again.
