Re: IBM Thinkpad boot problem

Get a new inverter. You shorted-out the one that you had while trying to replace it while on. A new one is necessary now. Make sure the power's off, the battery's out and you're grounded to something.

When booting screen is black just about make out the IBM Thinkpad logo.

It appears you have a backlight problem. This fault is caused by either a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to determine the fault and possible fix. :-

Hand-me-down IBM Thinkpad 600E 2645 has blinking LCD video XP O/S

This sounds to me like either your flourescent lighting tube is beginning to go bad ,,, or the inverter is going bad ... or even both. :-)

The cheapest and easiest solution for you is to simply replace the LCD screen (replacing the inverter or the tube are actually a bit cheaper, but not quite as easy to do - most computer repair centers will try to talk you into a new screen anyway). This is actually very simple for either you or someone you know who is an avid "do-it-yourselfer". IBM makes ity very easy. You will find easy, detailed instructions in the ThinkPad 600/600E (2645) Hardware Maintenance Manual, IBM S10L-9619-03 June 1999 available for FREE downloading in .pdf format on IBMs website. Follow this link to some really sweet deals on LCD screens for your 600e on eBay for under $35.00.

Remember you can always connect an external monitor to your ThinkPad until your new screen arrives if you have one. The manual should also give you instructions to change out the tube if you wish to save a few more bucks and try that route. Hope this will FIX-YA! Please leave your feedback and let me know!

Verical Lines in five or ten seconds after booting R50e ThinkPad

Possible loose connection from the inverter to the screen. you can try pushing the edges of the screen cover towords the center working your way around the problem area especially. But it could be just a bad inverter. Can you hook it up to external monitor? That will tell you if problem is before or after inverter.

Since you have replaced the inverter and the unit works with an external monitor, then probably problems would be with:
  • CCF lamps (backlight);
  • inverter triggers and/or B+ supply.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Try using a flashlight at different angles and let me know if you can see a faint image of the desktop If so It is your inverter board that needs replaced.

Boot sequence

161 and 163 error means you have to change your CMOS battery. open the laptop, change the cmos battery and you should be able to set the date and time.

after which you can access the bios by pressing F1 upon boot up and change the boot sequence after that

How do I find my Thinkpad 2647 cmos battery, to change it?

It is unlikely to be the cmos battery as there are signs [music] that your laptop is booting - shine a light into the screen if you can see an image but it is very dark then it is likely that the screen backlight is not working. If this is the case the most likely causes are a faulty inverter or a faulty screen cable - both can be obtained as a kit quite cheaply on ebay if you have the ability to fit them.

I would suggest changing the inverter first as it it the simplest and cheapest solution. inverters for the thinkpad can be picked up on eBay for a couple of ponds.
