Having problems with your HP Pavilion dv9000z Notebook ?

My laptop (HP Pavillion DV9000) startup issue.

\015 My laptop (HP Pavillion DV9000) has had startup issues for a long time now. It does what alot of others are complaining about. It tries to startup but there's nothing on the screen. After a few seconds it shuts down and restarts. It will do this over and over untill it finally works. I use to Do the static thing by holding down the power button for 30 seconds and it was hit and miss but would usually work. Of course now it won't fire up no matter what I do. I did some more searching around for solutions and read somewhere that it could be a CMOS battery related problem. I removed mine and tested it. It only has 1.3 volts. What I wanna know is, is this a big enough issue to cause the comp to not starup like it has been? In other words, if I replace the CMOS battery with a new one, would that clear up my startup issues?\015

Answers :

As you know CMOS is an on-board semiconductor chip (stores BIOS) powered by the CMOS battery you refer to, inside computers that stores information such as the system time and system settings for your computer.\015\012I have heard of issues when the CMOS battery is low (1.3 it should have failed normally by now), from boot inc other issues, so id say yes possible.\015\012The thing is any machine at POST boot is only as powerful and reliant as its Bios, which has given me another thought. Some companies when a system boots have the CMOS ROM copied to RAM as ram is faster, I cant honestly say if HP do this, was just a thought.\015\012

Hello. I have a hp pavillion DV9000, 17" screen. I am having an issue with the computer "freezing" on the windows xp loading screen. When i originally got the laptop (bought used) it worked fine. But now it stalls on the loading screen. It originally had vista, so at first i thought it was a vista problem. I tried some things, then eventually downgraded to XP. It will eventually load after 15-20 min or so, and once i am logged in, it runs very fast. Since i just reinstalled the os there is no st
