I cannot turn on the computer, and there are no indicator lights lit on the front. This is with the unit plugged in and not plugged in on battery power. Took the battery out and plugged it in and still nothing.

It is either the ac adapter or the ribbon/cable that connects from the power on button to the motherboard. I disassembled the same model with the same problem and found that the plastic cable/ribbon fastener on the mother board was broken. If that is the case you may be able to use some type of adhesive that is also an electrical insulator to repair the problem.

Go to the Toshiba site and make sure you have downloaded and installed the right drivers. Sometimes there are multiple drivers listed for the same laptop. Try another and see if works. If not, try another.

How do i replace a dvd rom drive in toshiba satellite a85 s1072?

There are one of 2 things that are happening. One, the reader on the CD drive is dusty, so carefully check the head, it is a luminescent bulbish thing in the middle of the open drive. Otherwise, your CD's (including past cd's) may have been dusty, and damaged the drive, in which you need to replace the drive. If your computer is under warranty then send it back and tell them this.
Good Luck

My Satellite A85 laptop will not turn on. There are no indicator lights lit anywhere. This is if I have it plugged in or on battery power. It is completely dead,.

The battery is flat and possibly the adapter or the power connector on the laptop is faulty and therefore could not charge the battery.
Get a multimeter and check the voltage on the plug that plugs into the laptop, it will let you know if the power adapter is faulty or not. If possible borrow one and connect it to your laptop, make sure the adapter is the same as your one.

Turn on

Have you checked your power adapter with a digital multimeter? Maybe run it by your local radioshack or computer super store if you dont have a DMM and see if someone can check the voltage on it. Maybe your adapter died, then the laptop was running on battery until it went dead.

Another quick check, remove the battery all together. Plug in the ac adapter... does it turn on? does it show any lit led's indicating it is plugged into the wall? try wiggling the connector at the jack on the laptop, does that light any led's or cause power to be restored?
