We have 20 Fujitsu Esprimo V5535. Operating System Windows Vista Basic. BIOS Version 1.03 Date 11/30/2007. After we purchased the we noticed two problems:
1. Does not wake up from sleep mode.
2. Struggles to start on battery. But starts on AC power easily.
We called Technical support. And they found no problem. Upgared BIOS, Video driver. Problem remains. We gave up.
After a year I searched internet again. This time I found plenty of other brand laptop has the same problem. Many solutions has been suggested. I started by downloading New BIOS V1.12. After I upgraded the BIOS the problem number 1 is solved. Even though there was a clear fault the technical support did not admit it. The problem was obviously with the BIOS. They have written new BIOS which has solved problem number 1.
Now problem number 2:
The battery is fully charged. Without AC adapter if I press the power button the laptop does not want to start. I will have to press the power button very hard. All 20 of the laptops has the same problem. If I plug in AC adapter the laptop will start very easily. A very soft touch on the power button with start the laptop.
If anybody has a solution for this problem please let me know.
