Most likely there is nothing wrong with the adapter but just in case test it with a voltmeter to make sure the output voltage is correct. Unplug the AC adapter, remove the battery and wait for 1-2 minutes. Try reseating the memory module, just remove it from the slot on the motherboard and install it back.
I finally managed to recovery the BIOS with a help of USB flash disk. For my computer and the BIOS version I use, the two files are 306DF15. Actually this model can be found in “BIOS Setup” (we can’t start it as the CMOS is bad)3. FD to USB disk’s root directory and rename it to 306 Hold the Power Button for 5 seconds, then release.9.
When you plug the AC adapter the power LED and the battery charge LED light up.
When you press on the power button the laptop powers up but will not start. If the power LED lights up it indicates that the laptop is getting power from the AC adapter.
Turns out muting my line-in in my sound control panel fixed it.
If your laptop does not start at all or it starts but will not boot properly, it’s possible that you can fix the laptop at home without taking it to a repair center. I’m not sure if I can cover all situation at once, so I will update this post as more examples come into my mind. First of all in this situation check the AC adapter. If you cannot do that, find a known good AC adapter and use it for testing the laptop.
Currently we accept Wi Fi whitelist requests for AMI, Phoenix, and Insyde BIOSes.
