Precision 7550 & 7750 Owners' Thread

Directly from Dell?
Next to none spare parts ob 3rdcparty websites as all of those machines are still on warranty.
Replacing keyboard its a breeze.
First time I removed it one of flex tapes was stuck on a foILll protecting PCB, andcI was forced to remove motherboard to free it so be careful and RTFM.

 

You can contact your local Dell spare parts department and they should be able to sell you a keyboard. Otherwise, they're also available on eBay. Specific steps to replace the keyboard can be found in the online manual for the system.

Thanks to both of you! I'll contact Dell and go from there.

 

Hi ov_Darkness!

I bought these ones for my 7750 and they worked very well:

Hi there.
Does anyone know if the 7750 with the intel gpu only comes with the dgff adapter to connect for example an nvidia dgff card?
Thanks

 

No...
If you have the HDMI/DP pass-through card (which is what you get if you buy a system without a dGPU), it will only have one DGFF connector, you'll have to source a few more of them to install an actual dGPU card. (You'll also need to come up with the DGFF power connector, and replace the system heatsink as well.)

 

Sorry ,what I meant was the DGFF power connector.
Any idea on the part number?
Thanks

 

Yes, the pass-through card would not include the power cable.
There was some discussion about this part earlier in the thread, I think. The part is system-specific. (You can't use a 7550 power cable in a 7750, nor can you use a 7730/7740 power cable in a 7750.) Even though the actual connector end seems to be the same between systems, the length and orientation is different.

 

Thanks for the info.

 

Hello everyone. I'd like to share solution for the Modern Standby (aka Connected Standby) problem I had with my 7550 (with Windows 10). After couple of times when the machine heated up to the point I literally could not touch it with bare hand (and had to use a towel) when it should have been sleeping, I started digging and found out that my 7550 by default uses S0 (connected standby) state for standby instead of normal S3, and that's a problem many Dell (and not only Dell) users encounter. Happily Win 10 20H2 has registry hack to switch back to S3, which worked for me: add PlatformAoAcOverride value of 0 to HKLM\System\CurrentControlSet\Control\Power and reboot ( reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0 ), and S3 state returns, as can be confirmed by "powercfg /a" command. Also all normal power plan settings like PCI Express Link State Power Management reappeared in control panel.
Interestingly (and happily), my 7530 did not have S0 standby issue and initially used S3 (don't know about 7540).
Hope this information may help someone.
