I found it on a Russian website but I don't know how to buy it, I still need that boardview model and Schematic appears like this Compal GDB55 LA-K621P Rev 0.2 BoardView
I have a Dell Precision T1650 MT workstation (of the following spec.) that was bricked yesterday when attempting to update the BIOS from A27 to A28 per:
- https://www.dell.com/support/home/en...-t1650/drivers > Dell Precision T1650 System BIOS
I received a device that requires BIOS maintenance. The problem with the device is: when powering on the laptop, sometimes it works normally, and sometimes it shows "no data",
and sometimes it displays 3 orange blinks and 6 white blinks.
I have tried many BIOS versions.
I performed a ME Region clean,
but the issue was not resolved.
The problem appears more frequently when using the battery without the charger....
I'm in need of assistance with a Dell Precision 5820 Tower. The BIOS is locked with "Dell Security Manager," preventing access to the HDD-1 hard drive.
**Background:**
I recently purchased this Dell Precision 5820 Tower from a recycler who salvages equipment from abandoned office spaces. The computer was left behind by its previous owner and was password locked. Given that it can run Windows 11, I saw this as an opportunity to upgrade my setup.
Does anyone have boardview and schematics for Dell Precision 3480 laptop?
Computer shows no signs of activity: 5V 0A is showing when the charger is plugged in. No means to test whether computer runs off the battery since the battery is currently dead.
No heat spots of any kind with the charger plugged in. No shorts that I can see. Both USB-C ports appear to be in great condition. TPS65994bf chip gets 5V but not switching on 20V.
Before I attempt to change the chip, perhaps other areas I can look in?
