This is regardng the below suggestion you gave earlier:
hi this is parveen smsc LPC47M172 IC near ddr ram slots count pins and short pin no 92 and 93 both and the motherboard power on and start giving display this method working 98% only 2% change the smsc PC47M172 ic . when mother not powering up than this smsc chip is faulty .
Instead of shorting these pins on SMSC, can we short the green and black wires in ATX 20/24 pin power connector.
solutiom for d845gvsr not poweringup only led flashing--
short pin 92 and 93 of smsc LPC47M172 with fine tip soldering iron .
pin 92 is nrsmrst signal that is 3.3v at time of working m/b when this signal is low than motherboard not powering up so we short pin 93 that is standby (3.3v) and motherboard powering up again and working properly this problem doesn,t come again in future. this solution is 98% working 2% chances to change the chip.

Here is the procedure, but you will need to call your carrier for the correct SMS center #. I will list a few below for you. Also, if entering the number doesn't solve the issue, you will probably want to get yourself a new SIM card, Here is the procedure:
1.go to your message settings and check the message center number to see if it is correct 2. call to your network operator customer care (if your number is not one of the ones below) 3. request the message center number... 4. note it down 5. go to message settings>message center number 6. insert the number which is noted by you and save it
Here is the SMSC # if you have AT&T:
For other carriers, try this:
On your phone, you can maybe get to this setting by dialing *#*#4636#*#*. We also call this the SMSC.
Lastly, for all of your other phone settings you may want to visit http://motorolasetup.tarsin.com That site will send you all of the current settings that you need and it sends the settings directly to your phone!
Dialing *#*#4636#*#* AKA *#*#INFO#*#* brings up a troubleshooting/statistics menu page. Dial that and select Phone information and at the bottom you can enter the SMSC (Short Mail Service Center) number. If the phone can receive but not send SMS it could be a carrier outage or issue 90% of the time. Try to update the SMSC number and powercycle the phone and test sending SMS.
You can find it in 'messages' -> settings
Every provider has its own smsc number. You can aslo check the manual from your phone how to change it. And check your telecom provider website for the smsc number.
See if the latest drivers are installed for the device, by going to Acer's website. If it is an old laptop and the same was working on the earlier installed operating systems, and now it is not working with new os .. check for the drivers. And if all of a sudden this happened check for a cable connector which might be right below the keyboard of the laptop. be carefull when you open the keyboard, and just follow the cable from the speakers and you will be able to locate the connector , check whether the connector is loosened of disconnected. Hope your problem will be solved, Cheers-parveen
I tried Parveens solution for this problem on 2 absolutely dead D845GVSR mother boards and it fixed the problem for me on both. On mine you had to permanantly short pins 92 & 93 of the LPC47M172 IC near the ddr ram slots.
There must be a reason for why the motherboard went dead in the first place because from the factory, pins 92 & 93 of this IC are not meant to be shorted. Albeit the motherboards work perfectly the shorting of pins on this IC get over the problem but the original fault is still really there but has been bypassed! Still having said that, what a result!
