Question about Panasonic (UJ-825-B) DVD±RW Burner

Four Beeps on startup on a Panasonic uj-810b

My Uj-810b in my sony Viao Notebook beeps four times when I turn on the computer. I can not get it to read any CD or DVD in windows or have it boot to CD. The Bios boot order is the CD then C drive. I am thinking that the problem is the drive is dead and not windows or the system, Dose anybody know what the four Beeps along with the flashing of the access LED mean?

Sounds like it's trying to boot to the dead drive- pay attention to the screen when you power on F12 or F1 whatever get's you to boot menu- change the order to exclude the broken drive- it should stop beeping.

At start up, before windows loads, a consistent series of annoying beeping occurs....

If they're occurring right as you turn the computer on, it's your Power On Self Test (aka POST) letting you know. Since I can't be more specific, here's a synopsis of POST beeps:

One single beep followed by three, four, or five beeps -- System-board problems, possibly with DMA, CMOS setup chip, timer, or system bus. The computer usually won't boot when this is the problem.

Two beeps -- The POST numeric code is displayed on the monitor, usually nothing to be concerned about, but you might google the code on another computer and see what you get.

Two beeps followed be three, four, or five beeps -- First 64K of RAM has errors. Solution is to replace RAM.

Three beeps followed by three, four, or five beeps -- Keyboard controller failed or video controller failed. Either you won't be able to see or type with this error.

Four beeps followed by three, four, or five beeps -- Problem with serial or parallel ports, system timer, or time of day. Check your BIOS settings (usually F2 at start up) to make sure everything is correct.

Continuous beeps - problem with power supply. Probably won't do much with this error. At the very best, your computer will boot and run very, very slowly.

Hope that helped.
