Question about Lenovo ThinkPad X41 PC Notebook
The backlight on my laptop does not start up until about 10-12 minutes at most after the computer starts up. Until then, I cannot see anything unless I lay the screen flat down on the table and view it from an angle.
Is there a driver I can install or something to fix this?
I'm afraid you won't be able to correct this with a software patch.
Two things can happen relative to the LCD backlight which is your developing problem.
- If the fluorescent tube has either lost gas or darkened internally, it will have to be replaced. These cost ~$80-$100 US.
- The inverter that produces the high voltage may be dying from a bad electrolytic capacitor but this isn't likely to be repaired anywhere since many of these boards (if separate at all, some are,others not) have components on them placed by robots that aren't good candidates for manual repair. The inverter boards should be available from the manufacturer or an 'authorized' repair station but they may not want to sell it to you and may ask you to send it in to them. I can't give you an estimate on the potential repair cost and they may replace the entire top section because they can charge you more and spend less time on the unit. If you can still see the LCD at an angle, it hasn't failed, but they may toss it anyhow.
