Replaced the battery but the WIFI card isn’t being detected anymore Wondering if you guys might be able to help me solve a issue where we removed and replaced the battery and now the WIFI card stopped working. I can’t remove the WIFI card as it is soldered to the motherboard. Only parts I removed was the IO board cable and the battery to remove and install the new laptop battery. Any ideas? Windows does not detect the hardware since the battery was removed. Update (09/14/2020) Manage to fix it. Not sure how. I took out the cover and IO board cable again and reinstalled it. Seem to fix it.
Hi, Get into BIOS and check: BIOS > General System Information > Device Information and check if WiFi device is shown as detected BIOS > System Setup >Wireless menu > Wireless Device enable to check if it is enabled. Here’s the service manual for the laptop which may help. It details how to get into BIOS and what all the settings mean.
