Hi,
I formatted the disk with W7 of my cf29 SN 5LKSB93925, I installed w10 and the programs I need for my work but, I don't hear the sound anymore, I tried to install its software but it does not install, someone can help me Thanks Geretto
Various sites report this laptop having Intel 915 chipset, and it is quite possible Windows 10 does not support it. If you really need sound, get a USB sound card.
