Hello, on my 700Mhz T20 firdt the clock stated running slow [changed battery - the same] then would not boot beyond IBM screen. Some Error codes indicated motherboard as suspect. I fitted NEW one, but not CPU - fitted original. This ran perfectly for a few days BUT clock still ran slow, switched off normally. Next start up just IBM screen, no error messages, no BIOS entry etc! I cannot believe a new [not s/h]motherboard has failed so I wonder if the CPU is dead? Any ideas very welcome, and where can I get another CPU - i assume it must be another 700mhz one?

You probably need to replace the BIOS battery. This battery is small and on the inside of the laptop connected to the motherboard. It stores the BIOS settings, date and time. If this battery becomes worn out then it will cause your issue.
First try and press F1. Navigate to the last tab and select to restore defaults, then save and exit. If the computer boots up fine but the next time you use it the same message appears then you need a new BIOS battery.
Alternatively your HDD may be damaged if it cannot find a boot device. Check your HDD is recognised on the boot menu by pressing F12, select it and press enter and your OS should boot.
Hope this helps,
Fail safe in the battery has engaged. See if the computer will start without the battery, using just the power supply. If you can get it started then put the battery in and see if it will charge or reset the fail safe. Give it about an hour, then shut it completely down and restart it with the battery in. If it won't start at this point, then you will need a new battery. Also change the CMOS battery inside the computer
Clean your memory card, or reseat it. Clean the edge connector with soft eraser if reseating doesn't solve it. Do this when battery is disconnected, completely turn off and no other power supply is connected to it. If not maybe ram failed already. This is the first step before going to anything.
For additional instructions try to find it in youtube.
Post us some update.tnx
check ur hd for bad sectors...shutting down for no reason is usually this(bad sectors)
also check system information and check device manager..could be software problem/incompatabilty/no drivers installed/or two devices trying to use same resource and shutting down cos cant.
Sound like a memory chip has failed. Try removing the memory, I believe these have on board, but not sure. If it doesn't have on board, you will need at least one chip in. If the problem is still there, try removing the CD drive, occasionally they can cause a no start. If it's not the memory or the CD drive, then try a bios flash. You will need to create a bootable disc from IBM's support site using a different machine (obviously).
If the bios flash doesn't fix it, them the problem will lie with the motherboard.
Good afternoon, Yan! Wish I could give you better news, but unfortunately, the video card is a part of the motherboard and not replaceable.
