Not able to recognize the SAMSUNG HM100JC on my Lenovo Thinkpad

If you are not seeing the 3g modem in Device Manager (Start > Run devmgmt.msc and press Enter, or access via control panel) try installing the driver for your systems 3G modem , which I believe is available in the link below, but enter the serial # etc. on the page just to be sure you get the right one. If the modem is showing as an "Unknown Device" or has a Yellow Exclamation Point displayed to indicate it as a non-working device in the Windows Device Manger, try right clicking on it, select uninstall, and check the box to delete existing driver software and reboot. Once rebooted, it should re-detect the modem and install the needed drivers automatically.
Note that from Device Manager, you can from the View Menu select "Show Hidden Devices" and see devices not normally displayed., so see if anything shows up there too.

If the device is working, but you are having trouble with it recognizing the SIM Card, you might read through this older thread and see if that helps.

Good Luck.

amazon allows these questions on the page an will send emails to several to answer this, many go directly to those that purchased that model .

Here's a site to cross reference: http://www.thinkpad-parts.com/listing.asp?pl=ThinkPad&cl=LCD

Change the BIOS to reflect output through dock(external Monitor) first.

There are audio drives for this laptop, they will work for Windows, XP, Vista, & Windows 2000. They are on this site:

http://www-307.ibm.com/pc/support/site.wss/MIGR-67856.html#audio

Just install and the laptop should recognize them. It if doesn't then that means the onboard video is bad.

what kind of media are you loading? is this a DVD or a program disc? If this is a DVD disc, try loading a music CD or other type of disc to see if it is recognized. If so, its possible your PC DVD is unable to recognize that specifc type of DVD. Try other DVD's which you know worked before using Vista. Even though your machine says the device is working properly, check the Lenovo website for updated drivers for the DVD and the board chipset. Let me know if updating the drivers does not work. Meanwhile, I'll see if I can find out any more information from Lenovo.

While I was not able to find that specific model of laptop, I was able to locate the CDRW Bay and based on my research this bay only supports the following models. Though it may look the same and even have the same interface, if it is not in the supported model list, it will not properly function.
