I have an IBM T40 that worked great until yesterday. When I powered it up, the 4 lights (battery, etc) flickers but the laptop does not power up. I removed the battery, paused, tried with and without the battery ~ same problem. Can someone help? Thank you

There are a few things left you can try. First take the battery out and make sure the unit is unplugged. Next push the power button a few times to discharge any power inside the unit. Now put the battery back in and while plugging in the unit see if the charge light comes on or flickers at all.

If it flickers and goes out, you have a bad power cord or worse a bad jack on the laptop's main board. If it never comes on, you have a bad power cord or mainboard. The battery is probably dead (doesen't have a charge left in it.)

You said this happens regardless of if the battery is inserted. Have you tried powering up the unit with no battery installed and just the power plug?

I'd see about gettting a replacement cord first. If that doesen't do it you probably have a bad board.

Check the power supply.Hope the notebook receives power from the battery or the Ac adapter.We need to ensure there is no issue with the power supply.boot the notebook to the safe mode.If it boots to the safemode perform a system restore.In case the notebook does not boot to the BIOS,connect to an external monitor.If we still do not get a display,its the video card

My IBM T40 boots to a black screen with the "z"(light at top to right of power.


Try these steps:

1. Remove battery and unplug AC adapter
2. Press power on button for 30 seconds or so (one min is also too)
3. Attach battery and plug into wall
4. Power "ON" as normal

If you are still getting the "Z" and a black screen then I would have the video card or hard drive looked at and replaced. Start with the video card and then look at the hard drive

Worked fine yesterday - will not turn on today - kitchen


When you say the machine is dead do you mean you are getting no LED lights at all or do you mean it is not booting up? No power and no post are two different things. With no power you get absolutely nothing at all. With no post you may have some LED lights but nothing comes up on the screen. You said power and power supply tested ok. How are you testing it? I need more info please.

I have an IBM think pad T40 that does absolutely nothing when I try to turn it on. It's actually my daughters, she sid it was working just fine then she shut it down and when she came back an hour later it...


Try taking the batter out and booting using just the power cord and Vice Versus'. Also when the power is plugged in does the charging light (Battery Indicator) blink or light up? If you know the Power Supply is good, then the Mother Board may have fried. If it's under warranty, take the Hard Drive out and send it in.

IBM think pad t40...the screen stays black. Shows


Are the activity lights blinking like the computer is doing something? If so the monitor may be disconnected from the unit or damaged. If so this is a pc repair issue, and a little tricky to do on your own.

My IBM Thinkpad T40 2723 will not boot up


The first thing to try is to unplug the power adapter from the computer then remove the battery. Then press down the power on button for a second or two. Put the battery back in and reconnect the power adapter and see if it boots.
