Laptop gives bright flash on starting

by Jani J / March 30, 2013 6:34 AM PDT
Dell Studio 1555 Note Book gives bright flash on starting. No beeps, No fan moving, No display, nothing but bright flash for a second. Battery charging indicator glows.

Is it a motherboard problem or CPU problem or it is something else?

Please advice.

What happens after this bright flash?
by wpgwpg / March 30, 2013 6:42 AM PDT

Does the laptop boot after this bright flash? Does it do anything else? Do you get an error message? Have you tried booting to Safe Mode? What version of Windows do you have? Do you have a repair disc? Do you have backups?

No, Laptop doesn't boot after flash, No it doesn't do anything else, No error message, As there is no any activity there is no question of booting in safe mode, Windows Vista, I don't have repair disc...... and I don't need backup (of data).

Can you boot from a CD or DVD?

To determine if you have a software or hardware problem you should get hold of a bootable disc and see if you can boot from that. Examples are Windows install discs, repair discs, system recovery discs, backup/restore boot discs. If you can't boot from one of these, you have a hardware problem and should take the computer to a service technician for repair.

Good luck.

As there is no activity other than flash, there is no question / chance to boot the system from CD or DVD. IT IS a hardware problem.Question is WHERE ???

Usually a motherboard issue.

But you as the tech would remove anything not needed to see the BIOS screen. All these items are optional. HDD, ODD, memory sticks save 1, and nothing plugged into the USB or other ports except maybe the charger.

And always try the generic reset noted in the welcome post of the CNET Laptop Troubleshooting forum.
