The on off power switch...lights up for about 3 seconds, then it cuts off for 3 seconds. It repeats this cycle of on/off until I have to disconnect the AC plug or battery! Also These events occurred after installing a new 160 GB hard drive for this unit.

Mother board failure in Compaq Presario C770TU Notebook PC

Dear,
My
Compaq Presario C770TU Notebook PC has an problem during windows installation. it hangs out during the installation process. when the step of 39 minutes is going on. earlier i have changed my battry from hp care centre. i have shown to IT person without opening the laptop he seems might issue of mother board.
please suggest me what shall i do.

Hello khadkemm,
You mention you are performing an installation of Windows. Is this an upgrade situation? What operating system is currently installed and what are you upgrading to? You may want to take a look at this page, and see if it helps.
You can replace the motherboard by looking at your Maintenance and Service Guide, but the software hanging up does not necessarily mean the motherboard is defective. Are you experiencing other issues and error messages? If so, what are they?
Please reply with more specifics and let me know if the info above helps.
Good luck!

My employer acquired a Compaq Presario C500 Notebook

My employer acquired a Compaq Presario C500 Notebook, PN: RQ337UA that is out of warranty. The hard drive has been damaged beyond repair and was not returned with the laptop. I need to purchase a hard drive & OS. How can I find out what drivers i need? I thought I could go to HP's website and input the PN and SN to bring up the laptop configuration, no such luck. What sort of problems will I run into?

Hi:
You should be able to get the exact model C500 series notebook your ER has by entering the product number in the applicable box at the link below to access the support and driver page for the notebook.

Audio driver doesn't work for my compaq presario r4000 notebook XP system

Hello,
I just reinstall Window XP on my compaq presario r4000 notebook, and I download
all the drivers from HpCompaq offical website. But the audio driver
does't work for my "Conexant AC-Link Audio
(PCI\VEN_1002&DEV_4370&SUBSYS_3085103C&REV_01\3&13C0B0C5&0&A5)".
Please help me to figure it out.
Thanks!!

OK...
Now we have to get creative!
Download and install the free 7-Zip utility.
http://7-zip.en.softonic.com/
Download this driver:
http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=US&swItem=ob-317...
Decompress driver audio Conexant CX20468-31 AC97 and Equalizer with the 7-Zip software.
Once installed, do a right click on the file sp30578.exe, select 7-Zip/extract the files and then click OK.
Force the installation of the driver manually:
In the device manager, right click on the audio controller, and select Update driver.
Select install from a list or specific location Do not search. I will choose the driver to install.
Click on next, Have Disk, and browse.
Select the cpl3085a.inf file in the uncompressed folder sp30578, and then click Open.
Click on OK, next and finish.
Restart the computer.

My Pavillion dv9700 notebook won't boot unless I first...

My Pavillion notebook won't boot unless I first boot to a cd. Here's the problem:
I have a dv9700 notebook. It wouldn't power up. A local shop said I needed a new motherboard. I ordered one and installed it. Now when I try to boot it gets to the part where the hard drive starts to spin and suddenly shuts down only to power up again and endlessly continue this loop. I have found that if I first boot to a bootable cd and then at the cd menu choose "Start Windows" instead of "Boot to cd" the computer will start Widows Vista and run normally.
I have reseated the RAM and tried only one card at a time and switched slots. The BIOS is up to date. I have booted on ac adapter only. Battery only. Tried another ac adapter.
The BIOS hard drive diagnostic fails, showing no hard drive installed. I have tried the hard drive in a USB enclosure. It read fine. I have tried another hard drive in this computer, still reboots over and over.
I can't figure out why I need to boot to a CD first then switch to Windows Vista on the hard drive.
Any ideas? Thanks

2nd HDD bay with HDD = notebook won't boot with HDD in 2nd HDD bay

I recently came into a Pavilion DV9308 Notebook. It was in decent shape, well looked new and since I like tinkering with laptops and the motherboard had the dreaded NVIDIA GPU failure going on, I sent the motherboard out to my motherboard dude and he put a newer NVIDIA video chip in, made some adjustments and modifications to the heatsink cooler etc. Along with my modifications including vent holes and sealing up the fan blowing assembly so when the fan turned on the hot air would leave the laptop it now runs Windows 7 64 bit with a 64GB Kingston OS SSHD and 4GB DDR2 800mhz ram. It runs like lightning and impresses people when they see it boot up in 15 seconds.
The problem is and the whole reason I picked this notebook to restore is because it has two acutal hard drive bays. Well ever since I've gotten the notebook It will not boot with a hard drive in both bays or a hard drive in Bay #2. I had to send the repaired motherboard back once because one of the ram slots wasn't working so this is happening on two different motherboards. I cannot find a reason why this is happening and have yet to find anyone that can help me with this. Can anyone explain to me what I'm doing wrong? I have all the correct drivers I think and the laptop runs at 130"F when pushed to the max! That is amazing compared to what it originally ran. It would be awesome if someone could please help me with this. Thanks.

Hello jason9922. I understand your notebook won't boot with a hard drive in the second bay.
When you say that the notebook won't boot with a drive in the second bay what exactly do you mean? Does the CAPS LOCK key flash or do you get an error?
When you have the hard drive installed can you access the BIOS? If so, is the hard drive detected within the BIOS?
I'll keep an eye out for your response. Have a great day!

Arch on Compaq Presario CQ-320LA doesn't boot

Hi, recently i got a new compaq presario CQ-320LA, pretty looking machine and doesnt get too hot
but sadly i cant boot the "CORE DUMP" release iso on it getting this freeze (no error, no panic, just freeze)
here is the snapshot of the the freeze
http://img512.imageshack.us/img512/7475/imagen048i.jpg
Looking at the point where loding freezes i traced the same kernel on my desktop pc and i supposed it is
calibrating the proccesor (the part where it displays the BogoMips of processor) so i tried supplying the kernel
with the mips detected with the 2.6.20 kernel with this parameter lpj=n ( Sets loops_per_jiffy to given constant, t)
but even it gets just 3 o 4 more printk kernel-messages to reach the freeze again;
on the other side i could boot and install arch DUKE iso with a 2.6.21 kernel. And from the installed system i tried to update to the
core dump kernel in the iso... so everything installs fine, the initrd generation too but when i try to boot with the 2.6.24 kernel
the same freeze
I've tried all the tips in the wiki (line kernel params acpi=off .. ) but nothing
I also tried checkng the dmesg output of sane system and i cant see anything suspicious. Just the clasic hardware detection and a ton of
ata driver errors saying the disc is resetting itself but in the end the SATA disc gets loaded with no problems
I've tried all other distros with same results (all of them dated to 2008 too)
So now i have a duke arch on laptop with a kernel linux 26.21 and xorg with embarassing 800x600 vesa resolution and
it worrks fine but to use the catalyst or the radeonhd xorg driver i need
at least a 2.6.25 kernel (the one in the CORE DUMP iso). The problem is that i dont have a network conection available, just my old, undated
but trusty archlinux reposiitory last syncd on june of the last year. I use the same packages (in a custom made dvd) on the desktop pc and everythin ok
Anyways, if someone does what could be the thing that freezes the load , please help me
The laptop specs are:
AMD Sempron™ para PC notebooks SI-42
Gráficos ATI Radeon™ HD 3200
SATA drive ( a SAMSUNG 160gb)
and 1g MB

does anyone uses presario anyway ?

Compaq presario cq 56 172 sr - booting from USB

Hi everybody!
I have a problem in my notebook(named as in topic) & I have not solved it yet. Maybe here somobody can help me?
The problem is : BIOS can't see and boot from USB flash as from USB hard drive but it can see the USB flash as a "USB floppy drive" - and can't boot from it.
In BIOS booting device order there are a few variants of USB devices to boot from - USB floppy and a USB hard drive.
I have a USB flash drive (Transcend, 4 Gb) with ISO image on it. Trying to boot from it on other computers and notebook was successful but impossible on compaq presario CQ 56 172 SR (I'd like my notebook to boot from USB flash)
I set the boot devices priority like this:
1. USB hard drive
2. CD\DvD
3. Notebook's hard drive
when I putting in USB flash and reboot the notebook nothing is changing - I can see only Operation system of my notebook hard drive but NOT the operation system on my USB.
when I changing the boot device setting:
1. USB floppy drive
2.CD
3. NOtebook's HDD
My notebook can recognize the MBR on USB flash (it is GRUB) - but everytime hangs and only rebooting helps.
How do You think, what is the reason that notebook can see the USB booting device only as USB floppy but not as USB HDD??
P,s: thanks for you answering. I hope somebody already had solved this problem before me

Recovery Manager could not restore Presario CQ56 & system won't boot, gives error BOOTMGR is missing

1. Product Name and Number

2. Operating System installed (if applicable)
Windows 7
3. Error message (if any)

4. Any changes made to your system before the issue occurred
There were no changes made to the computer, prior to the restore the computer would boot up, however, it would freeze after the system was up and running. Restarting the computer did not help and when I tried to restore it to an earlier point it said that it was unable to complete the restore. I then tried to the factory reset, however, it gave me an error message: "Recovery Manager could not restore your computer using the factory image. Please contact HP support. Error code: 0xe0ef0003. When I tried to restart the computer afterwards, it gave an error message: "BOOTMGR is missing, Press Ctrl+Alt+Del to restart". How do I fix this?
This question was solved.

Hello crossurmind.
What sorts of issues led up to the computer originally not booting? Were you getting a lot of blue screen errors?
The two items you posted from the error log seem to indicate that it is having trouble reading the hard drive and possibly the memory. After trying the restore it seems that it failed causing the boot section of the install to "not be found."
I think you should begin by using the built in tests for the hard drive and memory located in the BIOS. Follow this document to perform the hard drive test. All you'll have to do is repeat the process and select "memory" in order to perform the memory test. Make sure to post the result of both of these tests.
I will await the results; have a great day!

Notebook won't boot with usb device plugged

Hi,
Voila, I have a Satellite Pro Sp6100, when i try to boot it whith an usb printer plugged in, the notebook won't start at all. i have latest bios version 1.90.
Thx,
Barzot @+

Hello
It will be interesting to know if the printer is ON or OFF when you start the unit. I have tested my Tecra M1 with USB stick and the boot up procedure needs about 5 min. If I put the USB stick out the unit starts as usual.

Touchsmart tx2 notebook ,won't boot.

won't boot with repair disc or windows 7 upgrade disc,lights blink and can hear fan. any solutions?
This question was solved.
View Solution.

Yes, the 1 blink means your CPU has gone bad.
Unfortunately it needs to be replaced.
Either, if it's in warranty, by HP, or, if it's out of warranty by you or a friend/family member with some computer knowledge or if you don't have any computer savvy people in your immediate vicinity, you can try taking it to a local computer shop.
If your unit is indeed out of warranty, then depending on your location and how you'll be able to switch it (by a friend/family member or pay for it by the local computer store), the better option might be to replace it with a new unit if possible.
Hope I've been able to give you a bit of info that is of use to you.
