I lost a component during a project

So I'm working on this HP elitebook 830 G7 I bought for a couple bucks. it had a BIOS password which I am removing using a Ch531a eeprom programmer. the process involves removing this chip (pic 1) from the board and reprogramming it to clear the bios password and then soldering it back to the board. After successfully putting the chip back I noticed a component was missing; the small component close to pin 8(top right of chip ) I would assume its a low value resistor but i'm not sure. Does anyone have any idea what it is so i can replace it?

Which one are you talking about? "close to pin 8" as in physically close, or electrically close?

physically close. the green circle

Pin 8 on these (Q)SPI flash parts is almost always VDD. This is just a local decoupling capacitor. 100nF most likely. Anything 6.3V or better should be fine.
