Aorus 17G YD laptop, broken display, could not switch to external monitor

by ArchangelGabriel

Hello guys! I need a little help, I have one laptop for repair, it is an Aorus 17G YD, gaming laptop. Broken display, some cable ripped form daughter board connector, case broken, battery discharged and probably locked, etc. After I did the most tedious job I ever did on soldering back the broken cables (shielded cable) , I measured resistance on CPU and GPU core, 3 and 5 v ps and any coils I find on the board, everything seems to be fine. After I plugged the charger I don't get the power led light on from the charger connection maybe because the battery is locked , but on power button I have

How to force Acer Aspire Series to bootup BIOS/UEFI on external Monitor?

by maralexbar

I ask this question in general as there are many Acer Aspire models with UEFI Insyde BIOS that do not boot to the BIOS on an external monitor (VGA, HDMI, etc) showing only the Internal LCD (LVDS, eDP etc).

If anyone knows how to force the external monitor as primary for Notebooks of those models

I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

OTHER WORLD COMPUTING OWCTB3DK13PSL OWC 13 Port Thunderbolt 3 Dock - Disconnects when READING from External HD at high speeds

by KYBOSH

Weird one and way out of my league but I thought i drop it here in case anyone might have an idea on where to start looking.

I have a Thunderbolt Dock that has been behaving fine for a long time.
Admittedly I have only used it for menial data transfer tasks.

A few days ago I connected a USB-C external hard drive to it and wanted to test the transfer speeds.
I connected the proper high speed cables (USB-C to USB-C) and started the test with BlackMagic Disk Speed Test.
It wrote to the disk just fine. Got nearly 900MB/s+ write speeds but when it came time...
