When ordering batteries for your laptop the critical information to be concerned with is not your laptops model number, but rather the motherboard designation. For example the M-tech D9 F's HD has been M-tech's most powerful model for over 15 years obviously the motherboard and the power supply to that motherboard have changed drastically in 15 years. So the important thing to remember is that if you cannot find your laptops motherboard designation, which should be on the bottom of your laptop, then please feel free to email or call with your laptop serial number. This serial number should be on a barcode style label and almost always begins with PS2. Give this. Number to your technical advisor and he or she can confirm your motherboard model designation and thus assure you that you will get the right AC adapter. If you do not see the AC adapter listed after doing this kindly request that it be added to the list of AC adapters.
