Windows not loading, unable to start laptop
Dell Vostro 1520 notebook running Windows 7, worked fine around 2 years, but today got problem: when tried power on, it not load windows, stay black screen, and three active(On) indicators: numeric keypad icon(flashing), caps lock and keylock symbols. I tried unlock keyboard by by pressing keylock key, but this not help. Laptop not load Windows, nor allow shut down it via pressing "Power" button. I only can shut it down by unplugging power adapter jack. Notebook was powered from AC power supply, as internal battery was removed. I tried with installed battery, but as soon I swith the Power on, it just shut down after second or so. Is this hard disk problem, showing hard disk failure? |

I cannot say definitively what your problem is, but here is what I would do if the laptop were mine: Remove the RAM and clean the contacts before reinstalling it. It is not uncommon for the contacts to fail in contacting the connectors, and if they do, the computer will not start. Use either a pencil eraser or a cotton swap and alcohol to clean the RAM contacts. |

Check the codes shown he- http://www.bay-wolf.com/portpostcodes.htm It'll be a starting point, anyway. It looks like either a bad CPU or motherboard, unfortunately, from your description. -- Tciao for Now! John. |

My first look into a problem like you are describing is to grab one of the Live Linux boot CD's and see if the system will come up using that. If you are not able to make the system boot from the CD due to the system not allowing you to use the right function key or gain access to the BIOS then just plain unplug the hard drive and then try booting the CD. Either way if the CD boots and the system comes up then the problem is either just a plain corrupted version of Windows or the hard drive itself. If the system does boot using the Live Linux CD of your choice I would then download and burn a copy of the hard drive manufacturers bootable drive tester/fixer program and have a go with it. Should the drive testing software report no problem then it's probably time to bite the bullet and re-install windows. You can download an ISO file of many versions of bootable Linux at: http://livecdlist.com/ I'd suggest Puppy Linux as your first try since the download is small and it usually can figure out the hardware enough to bring up most laptops. |

Notebook power on then off, just after a few seconds. No blue device status lights shown anymore, no post. But at first time, when this failure happens, the device status lights showed LED error Codes in a no-POST situation, which was FLASH-ON-ON, which defined as possibly System board error, according to pic.2 Service manual: http://support.dell.com/support/edoc...iags.htm?~file =/systems/vos1520/en/sm/diags.htm Is there chance that this can be CPU failure, not motherboard? How to determine exact Motherboard model Part number? Is it possible find it without dissasembling laptop? I am wondering how much cost new motherboard? Notebook was very light used, only at home.

It's not completing the BIOS Power On Self Test. Check to see if it's still under warranty first. Use the Service Tag on the bottom of the laptop http://support.dell.com/support/topi...s_info/details Is the fan starting when ypu press the power on? If yes, skip to #2 . It probably overheated. If you're capable, disassemble and clean out the cooling system. Check for 5v on the fan plug when you start it up. No fan voltage? Motherboard is probably damaged. #2 Remove the AC adapter, all memory, main battery, Hard drive, CD-ROM, wireless card and CMOS battery. (Everything removeable that could be shorted out preventing the BIOS POST) Hold the Power-on switch for 60 seconds. Plug in one stick of ram and the AC adapter and try to start. Sometimes one of the memory BANKS go bad, not the memory. Put the stick of RAM in the other bank and try again.. Still no? Remove the RAM and put the second one in and repeat test. If it starts, replace another removed peripheral and retry until you find the bad one. If you get this far and it still won't start, you'll need a repair shop. Unk |
