I have a compaq presario v3000 that simply won't start. I press the on button and the top row of lights (on switch light, vloume control, mute and DVD player light) comes on but thats it. Occasionally i hear some faint 'boot sounds' from inside but thats it.

Have you tried connecting to an external monitor? Some times, there will be external video when there is no internal display. If there is still no post, check the memory to see that it is seated properly. If no Joy, remove user removable parts and try rebooting. If that works, replace them one at a time until the bad part is found. This is generic troubleshooting so it should work on any notebook.
Mine has just started doing the same. The HDD light eluminates, the DVD drive spins then the system stalls.
I have managed to get it to boot by pressing the 'esc' button continuously after pressing the power button until it starts 'maybe' but this only works while it is plugged in, if it starts on battery it will not boot at all.
I have tried changing the boot order but that made no difference.
The very first thing I would do is remove the laptop hard drive HDD and make a backup copy using another system. I use the freeware programs DriveImageXML or xxclone. You will need either a connector adapter to connect to the internal IDE cable of the host computer, or and USB2IDE+SATA adapter (this lets you connect either an IDE or SATA (3.5" or 2.5") disk drive to a USB port on a host computer.
A basic diagnostic is if you try to make a backup image and you can't even read the laptop HDD, then you know you've got a bad HDD or corrupted HDD data.
The second reason for making the backup is that in case during diagnosing the problem you accidently cause even more problems. This way, you have a way to at least get back to your current disk state if something goes wrong. This will be critical if you have no installation or recovery disks/media to restore your system if the HDD gets corrupted during diagnostics. Unfortunately, not all retailers provide a good set of recovery media.
The backup will also be very important if on the HDD you have unique and important personal data that have not been yet backed-up.
Also, with the HDD removed, the POST (power-on self-test) may respond differently and you may be able to get farther into the diagnostics.
Are you saying that at NO point, does anything show on the display?
Can you tell if your display backlight is turning on? Turning on very briefly, then going out, etc? Look particularly around the very edge of the display screen. You may see some level of backlighting even if the entire display remains dark.
On some laptops you still can just barely make out that something is actually shown on the display screen when the backlight doesn't turn on. It can help to have a source of bright light to move about and shine off the screen as you look for any images/text.
Also, while you're doing this, try pressing the key combination that cycles through the display choices (LCD/external/LCD+external) For example, on my Presario I think it's the F3 key. Yours may be something different. Check your manual. As was mentioned earlier, attaching an external display (including a TV to the sVHS port if you have one) could help diagnose this as well.
Something else one can try is to boot a bootable diagnostic/repair diskette or CD/DVD. With and without the HDD installed in the laptop.
You can try booting any one of the many diagnostic/repair/benchmark downloads. A download that provides repair/recovery tools is freeware Knoppix. It comes in CD or DVD flavors. The DVD contains more tools than the CD version. Knoppix boots your system in Linux, and the user-interface is graphical...like Windows. and helps bypass any problems caused by your HDD or a corrupted OS.
You can also try any bootable 'rescue' CD that came with the system.
...The HDD light eluminates, the DVD drive spins then the system stalls.
I have managed to get it to boot by pressing the 'esc' button continuously after pressing the power button until it starts 'maybe'...
I think you may want to open a separate problem, since you are able to boot (even if intermittently), your display is working, and you are able to get into BIOS setup (apparently).
I believe you're looking at a different problem...especially if you can try booting from a bootable diskette or CD/DVD and that boot reliably works even when booting off the HDD fails.
I have exactly the same problem on Presario v3149AU. One of these times WinXP actually sent an error report to Microsoft that responded with the message that I may need to minimize my hardware acceleration or find updates for the nVidia GeForce drivers.
Tried both but problem still persists. Planning to take it to the repair/service centre in the next coupla days.... still in the one year warranty period.
Mine is having the same problem, it began slowly... sometimes locking up blank-screenedly, and requiring a hard boot with battery removal, or a full drain and restart of the battery. This worked for a week or two, and then the battery removal / cold boot from full drain failed to work. Occasionally it will boot up and run XP, only to lock up and go blank. I only use it when overnights get boring at work, however it is so unreliable now that it's useless. It will go for only 10-15 minutes when it does boot. Never dropped, never mishandled, this laptop is now a useless chunk of plastic. I have tried to connect it to an external monitor, yet I have not delved into dissection. As it is, it is 3 weeks over the 1 year warranty. Any advice? I have seen in other threads very similar symptoms with other Compaq lines, with the ultimate fix being re-engineering the laptop to fix various problems.
Same company, same flaw?
It would appear the Compaq/HP have been using the same people to build this one as Dell did with the 1150. We'll have to see how HP handles this as compared to Dell having to have legal action brought against them. One step in the right direction is extending the warranty. What do you think?
Hi. Reviewed this thread for a possible solution to my problem. Compaq Presario V3000 was working fine until last night, March 14th. I know this was International 'pi' Day (3.14...) but that is a coincidence. Display shows JUST white. Boot sounds normal, DVD will play audio when inserted, same with audio CD. Keyboard shutdown works (MS button, u, u) and unit turns off normally. Computer had been dropped by previous owner and left side display hinge is loose. This is where the display cable runs. I replaced the top cover a while back and as I said, everything was fine. My question is, assuming the display has not failed (backlight works) can the display cable alone be the problem and can it be replaced.
Yes it can. Two things to check. Both ends of the cable. Make sure that they are seated into their connectors. If these are connected properly, you eather have a bad cable or a bad display(LCD). If you can connect an external monitor, you can complete any work that is on the laptop.
i had the same problem, but i fixed it. first you must take battery out of your computer and waight a 15 minutes. than take battery ang give it back to computer. press buton for start. when you press start than just keep pressing buton f8 all time. in five minutes will computer started runing. when it come to...winodws xp nalaganje... you can stop presiing f8... fist time tried to go...start windows normaly. if windows will not working than trie to go on safe mode....if you will come in windows look for virus and look startup if you close some program...
really sorry for my bad english
Since my laptop was still under warranty, I went to the HP authorized service centre in my city. They had to replace the motherboard; would have cost me around $500 but the warranty saved me!
It saved you this time.
I have had a chance to delve into this model and have found that it suffers from the same problems that many others do. The video chips are BGA (Ball Grid Array) chips. These chips work fine until the motherboard is flexed by heat or by the owner applying to much force when picking them up. The chip then pops one or more solder joints and the damage is done. This type chip has no leads and is soldered to the board by the smallest bead of solder. In the manufacturing process if the board fails testing, it is sent to an xray machine to see if the beads have shorted. if not, the board is reheated to re-flow the solder beads. When the board passes, it is sent to whom ever for making the computer. The problem with the xray unit is it can only see if a bead is shorted, not if it is not soldered properly. That is why many BGA chips "fail" in your computer. Some rework plants are using a bonding agent to try and bond the chips to the board to reduce the flexing of these boards. To correct this problem at the start, requires a thicker main/mother board to reduce flexing of the board. This requires forethought and attention to quality before the first chip is soldered. I'm done preaching now.
Hello Pratish, Your English is excellent! I will try the F8 trick once more but as I said, the machine acts and sounds like it boots normally. I just have a totally white screen. Thank you for your input!
And thanks to Willie for the insights, definitely wasn't preaching! Maybe it's because I am based in India (in a particularly hot city, Hyderabad) that this problem has occurred. I have been quite careful in handling the laptop; however, I did notice that the laptop tends to 'heat up' a lot while in usage. I don't exactly use an airconditioner to cool things down (my bit for global warming ) and maybe the heat's aggravated the problem.
Like you said, I'm saved this time. I am seriously considering buying an extended warranty so I don't have to shell out a humongous amount of money to get it up & running again!
By the way, Windows Update shows an 'update' to the nVidia GeForce driver; it's an optional hardware update but I am not quite sure if I should be going ahead and installing it. Any thoughts?
P.S. The new motherboard pops up an HP display logo now; it used be the COMPAQ one before the replacement. I am not sure it will make much of a difference though
