IBM T30 won't boot with LCD, but will boot OK with external eonitor
Water got spilled on the laptop, IBM T30. Dried and cleaned it. Now after pressing a power button it will work for 5 seconds and after that will shut itself off only when in LCD mode. If I switch it to external monitor mode it boots up fine. (Since it is not enough time to engage the external monitor with Fn+F7, I switch it with a lid close switch). Could you please give me a suggestion on what it might be? Thanks in advance!

It means computer developed oxide on some contact, and this is causing a short that forces unit to shut down, laptop must be taken apart, dried properly, and eventually cleaned with circuit cleaning solution. If problem stops when you turn to external display, then probably it is water or oxide in LCD ribbon cable connectors.

The bottom left key is labeled in blue, Fn. Hold down this key and press the F7 key at the same time. Repeating this will toggle between an external monitor and the LCD. If this does not work, try connecting an external monitor to the blue 15 pin VGA connector on the rear panel of your T30 and try this again. If you get external video you will know your video chip is working properly, but your LCD may not.
You didn't provide enough description of your problem to help you further.
Either you can hook up an external monitor or access BIOS setup (Basic Input/Output System) to replicate if the horizontal line appears. This step will check if the problem is with the video card or the LCD.
If you get the horizontal line on the BIOS or never get it on the external monitor, then surely the LCD screen is beginning to fail. You need to reinsert and/or replace the LCD inverter or LCD itself.
However, if you see the horizontal lines on the external monitor but not on the BIOS, try to update the video driver. If this will not resolve the issue, you need to replace the video card or the motherboard of your laptop.
Spill damage to a laptop often short curcuits the motherbaord inside and often ruins it. There are some vendors on eBay who offer a flat rate service where they guarantee that if they canntot repair the spill damage, they will return the laptop with NO CHARGE for the attempt.
I've used several of these vendors anit's about a 50% recovery rate so far. If they CAN repair it, they'll give you a quote qhich could be from $125 to as much as $250.
Go to eBay and in the searchbox type in "Laptop Motherboard Repair" and look through the auctions/vendors to find one like I described above. Otherwise, your only option is to find a local laptop specialist (like I am in my town) and get a price for buying and replacing the motherboard.
Do you hear any startup sound when you turn it on? If there is, try hooking an external monitor. If it has good display, replace LCD, if not then it may be a videocard problem. possible motherboard replacement will resolve this issue.
Try to attach EXTERNAL MONITOR to check if you have display from External Display and to confirm that your Laptop System is still working. If you got display from external monitor, therefore you have a faulty LCD / Inverter (gives your LCD a back-light)
It sounds like you may have the computer set to boot to an external monitor source. Try using the fn key and whatever "f" key up top that toggles the monitor source. if this doesn't work, try pressing f8 when booting up and boot into windows safe mode to see if it may be a driver issue or some kind of resolution issue.
When you connect a data projector or a monitor to the video output connector on the laptop you can toggle the display in various configuration by press and hold the blue Fn key and then press the F7 key (once or a couple of times as required) this key has a blue symbol of a pair of monitors.
Press it once the LCD will switch off and the display will switch to the external video output.
Press it again and the display will be on both the LCD and the external video output.
Press it again and the display will be only on the LCD.
You are lucky to have an external display! That means that your motherboard nor video card did not fry. Two possibilities here: the ribbon connector from the mobo to the lcd has been disconnected or your cathode tube/exciter is bad. You must have some electronic repair experience and laptops in particular for success here.
Every screw must be remembered as to its original location -lengths vary. ESD precautions must be observed (look that up if you don't know).
Follow the remove/replace procedures for the LCD and do not ever force anything. Here is a guide:
It is not difficult if you organize and use caution. Good luck, Steve Medley
