All in One Lenovo computer - display not working

I purchased All in One Lenovo computer, in Sep '23, sparingly used, (almost new).

I switched it on after couple of months (3-4), the display does not come on. Even the keyboard doe snot work. My son had a look, changed the batteries in keyboard and mouse. Still no display and keyboard doesn't work? He removed the power cable and pressed power button for 30 seconds, switched on, couple times, but no luck.

I called Lenovo customer service, they say it is more than 12 months, so not covered.

Hi @kbunique

What is the full model number of the AIO as shown on the product information label on the back?

Hi @kbunique

From your description it sounds like it is a Lenovo IdeaCentre AIO 3 27IAP7.

Does it mention either a model number of 27IAP7or an MT (machine type) number F0GG on the product information label on the back of the device?

This is just in case parts are required so as to link the correct ones.

Are there any beeps heard when first starting the AIO?

What is the status of the power light when the AIO is turned on, i.e. on steady, off, blinking slowing or blinking rapidly?

With the AIO turned on is there a display seen on an external monitor (TV?) connected to the AIO's HDMI port?

Thanks Jayeff for your interest !

Machine type is F0GJ

Product family is IdeaCenter AIO 271AP7

I do not hear any beeps on starting AIO.

Power light (white color) on the power switch itself comes on, steady. There are no other lights, indicators or buttons on AIO.

I connected the AIO to TV on HDMI 1 input, there is no signal / display.

Hi @kbunique

It seems as though the AIO is not even starting the power on sequence after the power button is pressed.

Things to check and try:

Check if there's 20V DC on the output plug of the power adapter for the AIO.

Check that the cable from the power button board is securely connected to the systemboard - see p.71 of the hardware maintenance manual for how to access the power button board.

I realize that your son tried a power refresh which was unsuccessful but sometimes a full power refresh is required to reset the BIOS if it has been corrupted for whatever reason and is causing the AIO not to start.

There's an RTC (Real Time Clock aka cmos) coin cell battery on the systemboard that needs to be removed so this can be done. Unfortunately for you, it is located on the underside of the systemboard so it will have to be removed from the case - see the procedure on p.78 (82 of 90 pdf) of the hardware manual.

Once the battery has been removed from the systemboard, measure its voltage. If it is <2.5V DC replace it. The battery model number is on the battery.

Having the battery out to measure its voltage gives enough time for the BIOS to reset as now there's no power on the board at all.

Reinsert the battery (or its replacement) in its holder on the systemboard (usually +ve on top as marked on the battery) and reassemble the AIO, connect the power and check if it turns on OK.

If it does then there may be a message stating that the date and time are incorrect. This is normal, as the BIOS has been reset. Once the date and time have been corrected the message won't appear the next time the AIO is started.

If it is still no good then there's a problem with the systemboard and the schematics for it would be required to find out what's wrong.
