This Plasma TV loses its menu settings whenever it is unplugged for half an hour or more. TV goes back to initial setting from factory, asking to choose language, country etc. It does this every time the TV is unplug for several minutes even after I go through the process of initial setup. I attach a photo of the mainboard. Any suggestions?

Not retaining settings. For some reason IC1702 comes to mind. But have no idea honestly just a quick guess. I'll let the more knowledgable folks chime in on this one.
I will say probability is high considering winbond is flash memory nand tech. -

It looks like the user adjustable settings are stored in IC601. Is that correct? This set has several eeproms IC103, IC601, IC802Attached FilesComment

by flat-eartherThe charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.
Windows also shows ''Plugged in'' when charger is not connected.
This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
If I let battery run out and say it has 3% Windows will... -

by vf faHi, so i guess I´ll have to make a new topic here, as i browsed through hundreds of other threads but couldn't find a solution to my problem yet.
I got a EIZO CX270 from a friend. He said it doesn't work anymore and wont display any signal or take any OSD inputs. Well, as an aspiring photographer I couldn't say no, could I? Thought it was an easy game, replace a bad cap and have a working monitor. But nooope, it wasn't supposed to be this easy.
So let me start with the problem description. I'll try my best not to skip anything so this might get rather long.

--> [F2] won't let me enter the BIOS. To enter the BIOS, I had to create a shortcut and then type C:\Windows\System32\shutdown.exe /r /fw /t 1 in the destination. This forced it to restart and enter the BIOS.
Once inside, I went to the BOOT menu, but, surprise, it wasn't there. I got the following message:
