If you you can dig into this...I would replace the eeprom. What you are saying, LOGO froze is the best indication. Replacing an eeprom in the field is not easy. In many cases a replacement board (also called, signal or main) will be replaced. As suggested, try to save programs first. Thanks for asking, Matt of Martins TV Repair.

I repair televisions, and computers are exactly the same. I have seen this problem many, many times in a TV. If I knew the location on the main board I could pin point it for you. The problem is a defective eeprom. The eeprom consists of eight pins. Four on one side, four on the other. These are now SMD’s (surface mount devices). You will in your case need to replace the main board. Also, the power supply may have one or two bulged capacitors (not good). Sorry….you may have to buy another laptop.
