HP/Compaq :: HP Pavilion Dv6428ca Won't Boot

Oct 6, 2009

I am trying to diagnose a friends laptop.

At first I thought perhaps the backlight went on it, but since then i've noticed a few other issues.

When I power on the laptop everything lights up and I can hear the DVD drive and HDD startup normally. But I get no HP splash screen and the monitor doesn't seem to power on either. Which I'm guessing means it's not posting, cause I even plugged it into an external monitor and it doesn't even pickup anything and goes to sleep mode.

After about 10-15 seconds it looks like the laptop reboots itself and starts up the DVD and HDD again but nothing...it just loops.

Is there something wrong with the motherboard ? I checked the monitor for a loose connection and the laptop in general for any internal loose connections and everything seemed fine.

My guess is the motherboard went and maybe the backlight at the same time...I have no idea...

HP/Compaq :: Vista: CPU 100% On Every Boot (HP Pavilion Dv2200)

May 26, 2010

I've had my HP dv2200 notebook since Vista came out and yes I've had problems with it, but I've never had this one.

Since two days ago, every time I boot up, my CPU is running at 100%. This is from a full start-up or even out of hibernation mode. After 10-15 it dies down to 5-15% but occasionally goes back up to 100% even when idle.

Besides going to the usual sites I go to, I didn't download anything or visit any sites I'm not used to going to. There was a Windows Update I had in my task bar for several days that I finally installed, but it didn't require a restart.

My anti-virus software is avast! free version (latest version w/ definitions updated).

Under task manager there are two svshost.exe's that jump around from 30 to 50, and Firefox is at 50 or so when I try to run it (which takes 30 seconds to open during the 100% cpu). And when the CPU does die down to 5-15% it says that 'System Idle Process' is jumping up to 95 which doesn't add up.

HP/Compaq :: HP Pavilion Dv9750ep And Windows 7 In Dual Boot

Jan 22, 2009

I own a HP Pavilion Laptop.

It says "HP Pavilion dv9000" on the screen frame, and says "HP Pavilion dv9700" and "dv9750ep" on the labels in the back. Guess it makes it a HP Pavilion dv9750ep?

It has 2 Hard Disks, each of 150GB; I believe it's 2 physical disks and not just partitions as in the device manager shows 2 ...
- WDC WD1600BEVS-60RST0
- WDC WD1600BEVS-60RST0

It came with Windows Vista Home Premium 32bit.

My issue is:

I'd like to try the beta of Windows 7, using the 2nd Hard Disk for that. I've been using it mainly for data backup, but as I have an external drive I guess I could make the 2nd dirsk free for trying Windows 7.

My reason for wanting to try Windows 7 is Microsoft Flight Simulator X. Some of my buddies tried it in Windows 7 and are reporting a noticeable performance increase.

When it comes to Laptops, and since this is my first one, I'm very reluctant to these moves - mainly because of the proprietary drivers... for instance, if I want to update my NVidia card drivers that must be made through HP and not through the regular channels - or so I think.

Questions:

Would it be possible to install Windows 7 on the 2nd Hard Disk and make it a Dual Boot system?

Would I have problems with HP-specific drivers?

HP/Compaq :: HP Pavilion Dv6000 Intel Motherboard 434723-001 Will Not Boot

Oct 10, 2009

I know that the dv6000 is one of the worst laptops but I still tried to repair it and got a new motherboard.

Initial problem: fried motherboard.

Got a refurb one off ebay now my issues is as following:

Press the on power button, fan spins for 2 seconds and computer remains on with no boot posting. Hard drive light is OFF and I can't hear the harddrive but I don't think it is the hd because I should still be able to access the bios and monitor should still light on. screen doesn't display anything. cd drive works and when I put a cd such as a windows disc you will hear it work for a couple minutes.

I tried everything from resetting the power cycle, removed the memory, harddrive, connected an external monitor, changed the little battery inside the motherboard. all power cables and ribbons are connected. keyboard won't respond though (fn light wont light on and ctrl alt delete produces nothing) ! I hate HP. after opening the computer I realzied what a piece of junk.

HP Pavilion 15-n003sq OS/Software :: Can't Boot From CD

Sep 14, 2014

why my laptop don't show me the CD option in (F9) Boot Menu.
 
I have to reinstal my windows (8) and I really don't have time to find an USB (I don't have one anyway..), so I have to make it to boot the windows from CD. I don't really understand why it doesn't work, after all, it worked first time when I instaled windows 8.

I search online for solution, but i find only the USB solution. This is not a solution for me I need to instal it from CD.. What if I will format all my partition disk ('till local disk C will delete a part of windows and it will colapse...) -> then will probably boot from CD?.. 
 
Safe Boot it's disabled in BIOS (anyway, it don't let me to enable it). Legacy Boot, i tryed with it enable and disable, I didn't saw a chage.

HP Pavilion 17-f114dx Display :: No Desktop After Boot Up And Log In

Jan 22, 2015

I have owned my new HP Pavilion 17 17-f114dx for only a month and it has worked great up to today.  When I start it, it now takes slightly longer to boot up and log in.  When I log in, I should see my desktop, but instead, I get a blank screen.  I am able to see my cursor.  I pressed control alt delete to see if anything looked abnormal and I am able to get to my task manager.  Things looked fine to me.  I am also able to right click a process and select "show location in folder" by doing this, it does bring up the folder.  I can navigate to my internet browser from there, and still get online to post this, but my desktop is not there. 

I have not installed any new hardware.  The only software changes that I made were an installation of a game and I tried to update my version of Adobe Flash Player which was unsuccessful for some reason. I have tried doing a hard reset twice with no luck and also tried plugging it into my TV and nothing has worked.

HP Pavilion DV6 :: Laptop Will Not Always Boot Up If Battery Fitted

Jan 26, 2015

Daughter's Pavilion dv6 Notebook will not always boot up beyond the HP screen if battery if fitted

Product number: WR498EA#ABUSerial number: [Personal Information Removed]

Operating system: Windows 7

Symptoms are that with a battery installed, the laptop does not always progress on start-up beyond the initial HP screen, which can be fuzzy at the top.  A solution is then to remove the battery and restart on mains, which is fine, but not convenient to always only rely  just on mains power. conducting battery test indicates requires calibration

HP OS/Software :: Boot Device Not Found On Pavilion 11-h013dx X2 Pc

Oct 28, 2014

  I have an HP Pavilion 11-h013dx x2 pc running windows 8 and this weekend all of a sudden my computer shut down. When I restarted it I was given a blue screen which gave me the option to restore and refresh. I tried both options but the computer shut down when it got to 15% of restoring. Then when I turned on the computer it gives me a black screen saying boot device not found. I hit F10, enter, F9, enter, then exited and saved, that did nothing. I ran the hard disk check which passed. I ran the memory check and that failed with the code RQDATS-6T079C-MFPWWK-002103. I can't remember what other screen I was on when I got a different error code, but this one came up as well at some point and I wrote it down RQDATS-6T079B-MFPWWK-001H03.

HP Pavilion Dv7 1451NR OS/Software :: Can't Boot From 2nd Drive By Default

Oct 1, 2014

My Problem: Can't boot from second drive by default

I have an HP Pavillion dv7 1451NR, product number NV204UA#ABA.

I have two drives installed. I have Windows 7 64-bit installed on drive 0 and Ubuntu 32-bit installed on drive 1.
 
I can successfully boot either operating system by the following procedure:

Power up
Press escape-key to get to BIOS
Press F9-key to get to boot menu
Boot menu shows two drives named “Internal Hard Drive”
If I select the first entry named “Internal Hard Drive” I boot to Windows 7.
If I select the 2nd entry named “Internal Hard Drive” I boot to Ubuntu.
 
I power up if I do NOT press escape, the machine boots to Windows after the timeout. My Problem: I want to boot to Ubuntu by default.
 
I've checked the HP bios and I don't believe there is any way to do this by changing the boot priority in BIOS. The BIOS doesn't seem to differentiate between the two hard drives. I only has one entry for “Internal Hard Drive”.
 
I believe an approach that should work is:

Use bcdedit or easybcd to create a BCD record that points to GRUB.
Create a GRUB config file that “chain” loads Ubuntu.
Use bcdedit to move the GRUB entry as the default.
I've tried various permutations but can't get it to work.

How do I discover where the initial boot image is for GRUB?

HP Pavilion Dv6700 Lockups :: Laptop Won't Boot Without Battery Attached

Sep 22, 2011

I have a Hp pavilion dv6700 series (dv6840el) and it just won't boot without the battery attached.
 
If i plug the AC adapter, i get some computer activity (fan, dvd drive noise and HD drive spins) for about 5 seconds and then shuts down.
 
Once i plug the battery (which is dying, needing a replacement), the laptop boots fine.
 
So, my question is: is this a motherboard or an AC adapter issue?
 
The AC adapter seems ok, though. But if i'm considering to buy a spare battery, i must make sure that i don't need a new AC adapter as well.
