lcd indicator lights + screen not switching off (inverter?)

Hello everyone, first post, first thinkpad!

I recently purchased an x60s without warrenty from the internet.

The fingerprint reader wasnt working but was fixed by opening the laptop and connecting the wire back to the motherboard. The chassis was bent but after searching this site found a fix by unscrewing the rescrewing several screws under the laptop.

Three problems remain with my computer, can you help?

1) There are 10 LED indicator lights beneith the lcd. Only the far left three are working.

2) The lcd backlight does not switch off when I close the lid. Yes I can tell!

3) The 8 cell battery is a litttle wobbly. Anybody else have this, maybe its nothing to worry about, or maybe a defective battery.

I phoned IBM support and obviously they said they wouldnt touch the machine. Luckily Ray was very friendly and said the indicator lights required a new inverter. Does anybody know if this inverter would also fix my lcd not switching off as I didnt know i had this poblem when I was on the phone. I can live without the indicator lights but I'd like the screen to swtich off and therefore I will only risk installing a new converter if it will fix my lcd backlight issue also.

Look foward to a reply, Cheers

There is a very small magnet built into the LCD bezel which activates a small reed switch located just to the right of where the LCD cable leaves the base. Perhaps the switch is positioned improperly or perhaps the magnet is missing.

If you remove the keyboard bezel, you will see a small "branch" of the LCD cable shooting off to the right and back. The small circuit board (3mm x 4mm) at the tip of this branch, which holds the switch, should be in its "slot" and should be secured via adhesive to the top back of the base.

The magnet is mounted to the inside of the LCD bezel, but can be seen as a small shiny piece of metal if you lift the left edge of the "clear plate" (the decal with the indicator icons).

Look a Item 7 on Page 81 of the following:

Note: You can use the "+" in Adobe PDF Reader to magnify the drawing until you see all the details clearly.
Good luck!

Thanks, I have checked the position of the cable and it is in the correct place. Perhaps there is no maginet, but i dont want to remove the lcd bezel in fear of the circle stickers that cover the screws not being secure when re applied.

Does anyone know a command that can manualy switch the screen off?

Does anyone know a way of switching off their screen without shutting the lid, ie, hold a maginet somewhere. This way i can test to see if its the maginet not working or if indeed it is the inverters problem.

Fn+F3 can be configured to turn off the LCD display. See this:

To test the switch:
Place a very small magnet near the small hole in the keyboard bezel, just to the right of the LCD cable.

wait..
i have a question..
how do you buy a VERY RECENT model thinkpad without any warranty..?
none at all..?
not even the ability to return it as defective..?

Correct. No warrenty. But I didnt buy it from Lenovo/IBM.

I purchased it online fom USA (ebay) I live in UK. The exchange rate was really good and considering computer stuff it 30% more to buy here I decided to go for it. I got an x60s, 2GB ram, blue tooth, fingerprint, atheros WLAN, Sierra WAN, 8 cell, X6 with multi burner, 65w charger for £1300. Would be £2200 if bought from UK lenovo. Some lights dont work and the screen doesnt switch off auto and no warrenty though.

Description said it came with 6 months IBM warrenty but it didnt.

DO NOT BUY FROM THINKPAD WORLD.

please help, would a new inverter solve the screen no tturning off when closed problem?

No, the inverter should not have anything to do with turning off the display. It does provide the voltage needed to light the backlight, but control over turning it on or off is elsewhere. As suggested earlier, your problem could be a missing magnet or a broken/misaligned/disconnected reed switch. Also, you should be able to manually turn off the backlight using the Fn+F3 key combination, at least that's what works on earlier systems.

Is the maginet positioned on the inverter card?

To access the inverter card does one ignore the manual which suggest you take apart pretty much the entire laptop or does one just remove the 9 screws from the lcd bezel?

edit: also does anybody know the part numbers for the stickers that cover these screws as IBM in the uk dont know what they are!

Cheers
