Question about HP Pavilion dv1000 Notebook

2 Answers


The MC was booting up - i left it for a moment and when I came back the screen was black & the MC seemed 'dead'. Prior to my leaving it a message came up bottom right hand corner which said something like '9 mins power' or something. I thought maybe that was to do with the battery but i rarely use it on battery. It was connected to mains power as usual. When i pressed the ON button nothing happened, it didn't even depress as normal and when i removed my finger the orange power light (? Looks a bit like a lightning bolt, second from right and next to the disc light - which wasn't on) flashed a few times then nothing. My husband thinks it might be the transformer which has a label on- it saying 'replace with HP spare and the numbers 33 (or it might be 38) 1090-001. I can't find the manual... will take it to PC world on Monday but thought I would try here first to see if anyone has any tips to save me the trip!

    Thank you for responding, pankaj - we did try that but the battery is still dead. I took it to PC World who informed me that the adaptor was the problem... so I bought a universal adaptor, set it correctly for my laptop (which is a HP nx6325) ... and it still doesn't work! So we now think the battery has gone beyond help and I may have to purchase a new one... and of course the HP website lists batteries, one of which looks almost exactly like mine with one small difference and my laptop model is not listed amongst the compatible products.... so I shall keep looking!

This was an odd one to fix. I found apon opening the machine that the heat sink was completly blocked with fluff (Picture Uploaded) so I removed it and cleaned it up.
I then removed the CPU, cleaned that of thermal paste and cleaned the pins with some universal lubricant (WD40 is fine, just make sure it's not wet when you put it back in!). I then applied new thermal paste (Get this at Maplin in UK) and re-assembled the unit.
Before powering on I removed the motherboard battery for 30 seconds with the mains power supply removed and the main laptop battery removed. The motherboard battery on this model was located under the WiFi card in the RAM bay and can be accessed by removing just the ram cover.
I then inserted the battery and the PSU power and switched it on. It booted to the CMOS screen where I updated the correct time and date, saved and rebooted it and it has been fine since.
I doubt this is a power supply error as the voltage output was correct when tested. Also this supply did not have the data pin (often found in Dell machines to tie you to replacing the PSU with Dell branded ones only) so it wasn't a data error.
Another odd thing is that when it had the flashing light error it would not turn on with just the battery installed even though the battery tested as fully charged. Apon repair the battery runs it just fine on its own.
You could just try removing the battery, PSU and motherboard battery (under the WiFi card) for 30 seconds to see if this fixes it, as it may do. I would then go to HP's website and see if there is a BIOS update under the 'Drivers & Downloads' section for your model. This could be a BIOS error that may have been corrected since your model was released or last updated. I am unable to perform this task at the moment as this is a customers machine and has a password. I shall however advise them to do this.
If you do need to strip it, I should warn that the plastic bezel above the keyboard is a bugger to remove. Make sure you have removed all of the screws under the battery as two of these secure it. Then prise up each end with a thin flat blade screwdriver or Stanley blade and push it up and towards the screen with some effort to unclip it.
Hope this helps some of you out, please rate and let me know.

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :-

It could possibly mean a faulty hard drive. But before we conclude, try to boot to safemode through advanced boot options. How to get there? tap on F8 as soon as your computer turns on. If you get the advanced boot option, then good. Try to choose the option that says Last known good configuration first. If it does not work, try it again but this time choose safemode. If all else fails then you might need to do a full re-installation of the operating system. If still trying to do a re-installation does not detect the hard drive, then you will need to have it replaced.

My HP Pavilion dv5 1125nr laptop won't boot up. The screen never lights up when the power is turned on, the little hard drive light next to the power light doesn't flash at all (normally it flashes...

check by removing the battery then put it back again power it on, or without battery power it on directly then check, if still the same problem, the fault is in the motherboard of the laptop, better take it the service center or consult some technician in your area

AMD Puma-based Asus M51Ta stalls at power up, screen is blank.

Have you tried booting and pressing F2 to get in the bios?
If that works you can check the boot devices and order of usage. Make sure the HDD is first.
Apart from that you can reboot and press F8 to get in the Windows boot menu, where you can try the Safe Mode.

If all this fails, the Windows configuration is somehow corrupt. You can try booting from a Windows CD and run the Repair option in the setup.

Try taking the battery out and use only the AC. If everything turned out fine, it could be a problem on the battery or on the port.
