its actually my dad's lappy..n he want me to install windows 7 in his acer aspire 4736..but when im done installing, it didnt detect the DVD-RW driver at My Computer.. in bios setup also didnt detect..i really dont know how to solve it coz it is PnP rite? someone could help me..
The fact the Bios doesn't see it, means it's not a win7 problem.
From your story I must assume you didn't install windows from a DVD.
A laptop's DVD drive can be taken out easily.
Try if you can push it further into the laptop.
If that doesn't help, one of several components might be broken.
The DVD drive itself.
The connector at the end of the drive.
The onboard ide controller.
On the bottom of the laptop remove the screw that keeps the DVD drive in place, and take the drive out and push it in again.
If that doesn't help, you would have to buy a new one and hope it's not the onboard controller.
They are not expensive, about 35 euro's, or $ 45.
Good luck
actually i am facing to the same problem also... i am using acer aspire 4736... after i upgrade my laptop from vista, by using DVD, the windows 7 cant event detect my dvd drive... and hence i cant install my laptop component from the acer software dvd.... any idea fot this? wat can i do nw is only transfer the data from dvd to my prndrive and copy into laptop...this need to use my frenz computer to read the dvd data....aiz..
HI,
I faced similar problem with my dvd-rw on 7.
Here is the solution:
After you install Windows 7 on your computer, you cannot access the DVD drive, or you can only intermittently access the DVD drive.
This problem may occur if you use one of the following DVD drives on the computer:
Work Around:
- Sony BC-5100S DVD
- Sony BC-5600S DVD
- TSST TS-L633B DVD+/-RW
To work around this problem, try the following methods in the order in which they are presented. Method 1: Check for a firmware update
To check for an applicable firmware update, contact the manufacturor of the DVD drive. Method 2: Disable the Adaptive Link Power Management (ALPM) feature
If you cannot find a firmware update, disable the Adaptive Link Power Management (ALPM) feature on the computer. To do this, follow these steps. Note ALPM is a feature that puts a hardware device into sleep state after 100 ms of idle time. This is a power-saving feature. After you disable ALPM, you can still configure the drive to run in any one of three power plans: Performance, Balanced, and Power Saver. However, you cannot still benefit from the additional power saving that is provided by ALPM.
- Click Start , click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
- At the command prompt, type the following six commands in the order in which they are presented. Press ENTER after each command.
- powercfg.exe -setacvalueindex 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c 0012ee47-9041-4b5d-9b77-535fba8b1442 DAB60367-53FE-4fbc-825E-521D069D2456 0

FIRST OF ALL A BIG THANK YOU TO...
Microsoft for all the wasted hours/days and for messing up my computer - yet again!
ACER for ignoring the problem and forcing me to buy an external DVD drive, nice machines but your customer service is rubbish - I certainly won't be buying ACER again.
PROBLEMS
- Drive disappears in Windows Explorer;
- Drive reappears when tray opens or closes;
- Have to reboot computer to see drive.
CAUSE
This problem occurs because the SATA driver (Msahci.sys) implements new power management functionality that is known as Adaptive Link Power Management (ALPM). ALPM is a feature that puts a hardware device into sleep state after 100 ms of idle time. This is a power-saving feature. Some optical drives do not behave correctly with ALPM enabled, and therefore these drives may not be recognised by the computer. The following is a list of some DVD drive models that are known to exhibit this problem:
TSST TS-L633B DVD+/-RW [SAMSUNG]
SONY BC-5100S DVD
SONY BC-5600S DVD
PLDS DS-8A3S [DELL]
FIXES
METHOD 1. Update the DVD firmware;
METHOD 2. Manually turn off ALPM.
========================================================================
Method 1: Check for a DVD firmware update.
========================================================================
NOTE: I take no responsibility for any none working drives or damage cause by the flashing process - you flash your drive at you own risk!
All I can say is flashing the drive with the SAMSUNG firmware on my ACER TS-L633B DVD drive worked for me. I was without a DVD drive for months and had already bought an external replacement DVD drive, so I had nothing to lose anyway.
After the flashing process my ACER DVD drive was recognised by Windows 7 as a SAMSUNG DVD drive, because the flashing process changes the OEM CODE to from AC01 [ACER] to SC01 [SAMSUNG].
After a reboot, Windows 7 loaded the SAMSUNG driver. I now have a fully functional working DVD drive, that doesn't disappear in Windows Explorer and will burn and read discs. I haven't burned a DL disc yet but it can read them, I don't foresee any problems though, fingers crossed.
CHECKING THE DRIVE TYPE
You need the drive to show up in Windows Explorer. Open and close the DVD tray if you DVD drive disappears, you may have to reboot.
Check drive type in Device Manager: Start > run > devmgmt.msc
THIS EXAMPLE IS A TESTED AND WORKING FIX FOR AN ACER TSST TS-L633B DVD+/-RW DRIVE [MANUFACTURER: SAMSUNG]
1. DOWNLOAD THE SAMSUNG WIN INQUIRY UTILITY [WININQUIRY.exe]
This is a program to check the drive name, firmware name, and vendor name while upgrading the firmware of a model that is not supported by firmware live update system.
DOWNLOAD: SAMSUNG ODD SERVICE
----------------------------------------------------
SAMSUNG TSSE WIN INQUIRY (ORIGINAL FIRMWARE):
DRIVE: TSSTCorp CDDVDW TS-L633B AC01
MODEL NAME: TSSTCorp CDDVDW TS-L633B
VERSION: AC01
OEM CODE: AC [ACER COMPUTER]
----------------------------------------------------
2. DOWNLOAD THE LATEST SAMSUNG FIRMWARE
TSDNWIN.exe is a program that supports the downloads of SAMSUNG firmware in all Window Operation/Systems ( O/S environment).
DOWNLOAD: SAMSUNG ODD SERVICE
- Firmware file: TS-L633B_SC01.exe
- Extract the files from the compressed archive (TS-L633B_SC01.exe) using 7zip.
TS-L633B_SC01.exe consists of two packed files:
- TSDNWIN.exe
- TS-L633B_SC01.bin (the firmware file)
TSDNWIN.exe will not update the firmware on an ACER DVD drive because it is meant for SAMSUNG drives. You have to stop it checking the OEM CODE using the command from a DOS window.
NOTE: Close all programs and if it's a laptop make sure the computer won't power off, make sure it's connected to AC mains power.
1. Start > type cmd
2. Right click on cmd.exe
3. Select > Run as administrator
4. Change to directory where TSDNWIN.exe is located [cd (dir)]
3. Type: TSDNWIN.exe -NOCHECK
5. Hit enter > should now flash drive, fingers crossed
6. Reboot.
7. Windows 7 will probably install a new DVD driver for your 'new' SAMSUNG [OEM: SC01] DVD drive.
8. Run SAMSUNG WIN INQUIRY UTILITY [WININQUIRY.exe] again to check.
-----------------------------------------------
SAMSUNG TSSE WIN INQUIRY (NEW FIRMWARE):
DRIVE: TSSTCorp CDDVDW TS-L633B AC01
MODEL NAME: TSSTCorp CDDVDW TS-L633B
VERSION: SC01
OEM CODE: SC [SAMSUNG COMPUTER]
-----------------------------------------------
SAMSUNG FIRMWARE UPGRADE INFORMATION: Firmware upgrade method
========================================================================
Method 2: Disable the Adaptive Link Power Management (ALPM) feature.
========================================================================
In order to disable ALPM users will need to first open a command prompt.
1. Start > type cmd
2. Right click on cmd.exe
3. Select > Run as administrator
4. There are a total of six commands, commands must be executed in the order below.
MANUAL WORKAROUND: FIX: The DVD drive is not recognized after you install Windows 7 or Windows Server 2008 R2 (MS Hotfix information)
