Due to lack of luck, these 2 buggers left their spot when I replaced the BIOS chip. SSD died a month later, but probably because it got too hot, because it wasnt removed from the board, long story. Then I baked the SSD, it worked for 2 months then again, sometimes boots, sometimes says no HDD. Everything should be fine on the board, except these 2 milletric buggers arent there. I dont have the stuff this small to resolder them, so I used the laptop without them. Now Im scared to put new SSD because Im not fully sure this one was killed by heat-gun. Another problem now, fans kick on 100% as soon as I click the power button. What should I do, can the laptop work without these 2, or these 2 are culprits for 1 or both of these issues?

Re: Help with Elitebook 745 G5 capacitors
The two capacitor are likely for the output of the buck converter ic U60400, Yes these need to be in place.
This is a step down buck converter, without the capacitors the output voltage is likely wrong and may have damaged whatever this regulator supplies.Last edited by R_J; 01-08-2022, 08:23 PM.

See attached for the regulator with '1U=' markings datasheet.
Do you have any soldering tools?
It could be an RT8097ALGE https://cdn.badcaps-static.com/pdfs/...7ce396bf51.pdf Ending in E , SOT-23-6 .Marking 1U=
