How to fix flashing lock with A in it computer won't boot up vos

How old is your laptop? if it is over 5-6 months it could be because of a faulty battery. You may want to upgrade or change your battery.

The good news is that your laptop powers on and you have a display. The bad news is that you laptop is trying to boot up from an OS (operating system software) like XP, Vista, or Win 7. Ether your software is corrupted or you have a problem with the hard drive or hard drive controller.
Press and hold the <Fn> key while powering the system on. This will run the Dell Diagnostics. Another more intense diagnostic program is located on a Dell CD that you should have received with your laptop. Look for one that has "Diagnostics and utilities" listed under the "Contents". You will have to boot from that CD disk. To do this, power on your laptop and tap the <F12> key to bring you to the "One time boot menu". Insert the CD and then select CD/DVD drive and hit <Enter> key. Select the "Run the 32 Bit Dell Diagnostics".
If diagnostics pass then your software is corrupted and needs to be reinstalled.

Your motherboard is most likely broken. While you can replace this yourself, the easiest way to have it fixed is to bring it into a computer repair shop, or if you are still under warranty, just send it to dell and they will fix it for you.

It's probably the motherboard at that point. Especially if it doesn't give you RAM error beeps on start-up. The only other things I would attempt is to remove the hard drive and the optical drive individually and see if that works. If not then it's the motherboard.
Hope this helps and please rate.

this is most likely a startup(bcd boot)error. the only way to fix this is to run setup from your recovery partition (shift f10) when starting up the computer or use a windows 7 install disk and select repair my computer when it comes up instead of installing. let the program go through the first repair attempt to repair startup and then restart the computer without the disc in the drive. should repair the problem, but if not you can alway reinstall windows. heres a tip...stop downloading illegal movies/software because this happens when you download torrents and viruses.

it sounds like your ac adapter has burned out and won't charge anymore. That's very common... that's why they are so cheap on ebay. Either that or your power plug on the motherboard is cracked or loose at the motherboard (2nd most common) and last bad motherboard (don't assume this unless last resort.)

Reset/replace the Ram/memory. Sometimes faulty and failing ram can keep a computer from booting up. If you have 2 sticks, take one out and then try to boot, then try with just the other stick. The flashing caps lock icon means a general failure, though it is most commonly associated with the motherboard.

I think that you would have a hardrive issue find out if your laptop uses an ata drive or an sata drive and i would look into getting a new one. if you have any further questions you can email me at [email protected]

See if you can run the Pre-boot System Assessment (PSA) diagnostics. To run the PSA+ Diagnostics on this system, perform one of the following actions:

1) Hold down the <Fn> key while pressing the power button.

2) Turn on the system, press <F12> at the initial Dell™ logo screen, and select “Diagnostics” from the boot menu.

3) Disconnect the AC power and remove the battery. While holding down the power button, insert the AC connector into the back of the system. The system then starts and the message “Diagnostic boot selected” displays. The system then launches the PSA+ Diagnostics.

According to Dell specs, there is no error code listed that you described, (Flashing Caps LED). Also try reseating the memory modules, (you might want to try this first).
