Hi mates, in my dell lattitude laptop motherboard was gone, so i gave it to local service person, so he said he changed the motherboard and charged 15k. I wish to know whether he changed my motherboard or not. please tell me how to check whether motherboard was changed in my laptop or not.
You can check with Dell and possibly get a serial number for the MB. And you can ask for the defective part or parts back.
issue is they could have changed it and reflashed serial with dell asset tag util. or they reflowed the video chipset and called it a day and not changed board. look under memory door. usually has a sticker with numbers .. should have taken pic of it before repair. see if anything changed on that sticker.. position.. numbers.
Serial number can tel you but for that you should know it first, if you don't remember it then probably its tough to answer this.
Thanks for your response mates. the only thing which notified is he changed the windows 8.1 OS key and i have already disabled computrace software before i gave laptop to him for repair now its again in deactivation stage. And i have already asked for old motherboard what he replaced, but he said, Dell wont give the old motherboard, because for new motherboard he said we have to submit our old motherboard to dell then only they gave a new one when you are purchasing. I asked him why did they need the repaired motherboard, he just replied just to avoid refurbished, is it true.
This "local service person" - do they have a good reputation? Most small shops can't afford to stock every laptop motherboard, so they would have to order it. How long did the repair take? If it was 1 or 2 days, I'd say you have the same motherboard. If it was two weeks, it could well be a new motherboard. It should appear absolutely pristine - not a speck of dust anywhere. You state the "motherboard was gone". Was that your conclusion, or that of the local service person? Where you given a quote before the repairs? It's all pretty hard to say.
It is near the parallel port if your motherboard has parallel port. And a motherboard without parallel port check PCI slot at the center of the port. Serial number is in a combination of alpha numeric values.
You can check your warranty status using your Dell service number. It's an alphanumeric that is specific to that unit. It will list when you bought it and everything that shipped with it. It will also list the parts in the unit by part number. If your service guy says it was replaced under warranty and it is out of warranty, he's lying to you. And I'm fairly certain for it to be replaced under warranty, Dell would have to contact you if you bought it directly from Dell. If you bought it used and the previous owner didn't transfer anything to you, you are likely out of luck.
This eludes me why would someone say they did something they did not like change a motherboard .... Sheesh for 15k I will change 50 laptop motherboards. Enjoy! providing we are talking USD lol!
There is no possible way the "15k" the OP mentions can mean 15,000 United States Dollars. I don't believe it. Rubles, yes. Yen, yes. Pesos, yes. USD, no! Well, perhaps if it was gold plated and Steve Job's favorite laptop, then maybe.
Boards cost me $50 - $150 USD (usually lower end laptops - HP, Gateway, Dell etc,). I only charge $50 to remove/replace the board (takes about an hour to an hour 1/2). One can look for scratches around the seams where the upper and lower casings come together (look close all around & also round the edge of keyboard for possible signs of prying). Look closely at any visible screws for stripping and/or off-coloring (even missing screws). Look under battery as well. Those are the only non-invasive ways I know of without having exported any previous mobo info. Now ripping it apart would reveal.
