ACER 5720 T520 DVD Drive

You probably need a new CD or DVD drive. Search eBay for your model # and DVD drive. They are fairly cheap and easy to replace. Almost any drive will work from other laptops, you may just have to transfer the bracket and connector from your old one (you just need a small screwdriver). Good luck!

Hi,

Load a disc and listen.Does the player make squealing noises or is it totally quiet? Squealing noises may indicate that the player is trying to synchronize with the disc but can't due to an obstruction on the lens or in the laser path inside the pickup or a defect in the pickup. This can also be caused by an intermittent signal problem due to a faulty ribbon cable.

Totally silent means that the photo sensor is not getting any usable input from the laser at all, meaning that the pickup is "blind" for lack of a better word.
This can be caused by an obstruction of the beam by foreign matter on the lens or inside the pickup all the way to a marginal or failed laser diode and/or photosensor array. This can also be caused by a bad ribbon cable with one or more severed traces.

You could try to clean the optics. This is the most common malfunction as far as i know in all disc players. It would involve taking the cover off and finding a way to expose the lense, and then cleaning it with a very gentle brush. some players have a cover for the lense that swings to the side during playing, this greatly reduces the chance of dust accumulating, but its still worth the try.

If you actually see dust on the lense, then its just that simple. clean, close, play.

It may also be worth your while to check on the small shafting that guides the carriage of the laser pickup. Dirt, grome, dust and solidified lubricant can cause stoppage of the carriage and the laser eye then fails to read the next track.

If the problem does not get solved then you have to get it repaired.

Goodluck..
Please don't forget to rate the solution.

there should be just one screw directly behind the dvd drive in the centre of it. you might have to remove the cover for the memory/cpu to get to it. remove that screw, start the laptop, eject the dvd, turn the laptop off and then gently pull the whole drive and it will slide out.

Is it really a DVD drive? DVD drives can pick both with ease but a CD drive cannot pick DVD's.

well the only disadvantage there would be moving them together..whereas if u have one fitted in it will reduce that.

Is the laptop still under manufacturer's warranty?
Was it purchased on a credit-card that offers an "extended" warranty?
If not, then purchase an external CD/DVD unit, because that will be less expensive than buying a replacement from the manufacturer, and paying a qualified computer-technician to disassemble your laptop, remove the "dead" drive, and connect the "new" drive.

No Sir, Acer Aspire 4330 comes with different Optical Media Loadings, ( You can see a pdf file here )
Like;

• DVD/CD-RW combo drive
• 8X DVD-Super Multi double-layer drive.

But you have the first one, The Combo drive not the super so you can READ both CD's DVD's but can write only CD's.

Hope this removes your dilemma.

Hello:

If you want to restore your laptop to factory setting: You should insert your "recovery disk to the CD/DVD ROM. and then shutdown the laptop.

Now; boot your laptop using the recovery disk(boot the laptop from CD/DVD rom) This will no need to input the password: its either you have to restore the system without deleting the existing files or you have to partition and format the hard drive. formatting hard drive you will end up with fresh copy of system files. same as first day when you purchase the laptop.

be sure to install the driver if there's any.

However; if you tend to do by supplying the password. iguess all factory installation has no password. you have to strike the enter without supplying any password.

may this help,

Yes, this is probably due to a CD/DVD drive that has gone bad. You can purchase a replacement drive from the manufacturer - ACER or you might also want to try looking on Ebay.
