Lenovo Flex 2 Screen wont turn on

My Lenovo flex 2-14 20404 has suddenly stopped showing any display.

It was working fine and then i put it back into a laptop case, (without shutting it completly down) and opened it a few hours earlier and no response. The battery light is flashing and it seems to power on and off but nothing else.

I have read alot of things suggesting that i should take out the battery but i couldnt do that with this model as the battery is connected to the laptop as i found when it was opened up.

Any advice would be greatly appreciated.

 

Thanks

Re: Lenovo Flex 2 Screen wont turn on

I have read the lengthy post which seems to indicate that this may mean that my laptop is in fact stuck in sleep mode.

It seems alot of people are able to turn their laptop on sometimes and change the settigns, mine however is stuck and has no display at all.
I saw the post about taking out the battery but i am just unsure how to disconnect the battery from the motherboard and not a tech guy at all so i dont want to break my laptop completly

Re: Lenovo Flex 2 Screen wont turn on

Hi conorquin , 

 

Welcome to the Community Forums. 

 

Power status indicator :blinking may indicate sleep mode (page30).

Screen blank state : (page 25) may need to be pressed hotkeys (page 5) .

 

Directions to power drain by removing the battery here on the hardware manual (page 39). 

Checking / reseating LCD cables can also help.

Service training for the model here .

 

How about connecting the laptop to an external monitor? 

 

Update us how things go. 

 

Regards

Thanks for the response! Any help is appreciated,

 so I've tried removing the battery both normal and caos battery but didn't get anything. The fan starts up and lights on the side turn on but nothing else.

i have connected it to another screen and nothing.  It's only about 18 months old so really hoping it's not the end of it

Hi conorquin , 

 

Greetings. 

 

Would tapping on caps lock and numlock show any lights?

You may try to remove the RAM and see if the system would beep. 

You can remove the harddrive for now and see if there is any display.

Use one memory at a time (even without the harddrive ) isolating it from each slots available. 

 

Check if there is any loose parts like heatsink and fans ( check if need some thermal paste on CPU)

Note that if you need advance skill or tools to perform better have it done by any service center available nearest you or call in tech support to send it for further test and isolation. 

 

Update us how it goes.

 

Regards

Re: Lenovo Flex 2 Screen wont turn on

So I brought it into a shop and they checked everything. They said they don't know and said they only thing left to check again was the motherboard which would cost around 300 pounds.

 

very disappointing that a laptop which cost nearly 500 pounds 18 months ago is now broken beyond repair and there's nothing I can do, no way I'll be buying Lenovo again.

Hi conorquin , 

 

As from what is happening , graphics chipset may be the probable issue . 

We had similar case that ended up for a reball / reflow but as such requires very advance steps.

 

Refurbished motherboards may offer lesser pricing and other parts of the laptops would still have a good resale values. 

Your data in the harddrive would also be viable as well as the RAM , CPU and LCD. 

 

You may review your options as what is best for you. 

 

Regards

Thanks,

 

is it worth trying to sell for parts? Or will not knowing the problem with it stop any one buying it ?

Re: Lenovo Flex 2 Screen wont turn on

Hi conorquin , 

 

Having worked with a lot of laptops of different brands and makes , they do happen most on laptops than desktop.

Laptops are meant as a mobile device , compacted to an enclosed chassis and embedded VGA cards on the mainboard. 

 

As technology increases software and hardware wise , the features and demand on each parts also increases .

Motherboard level of troubleshooting are advance steps that requires a lot of time to isolate as it would be easier for servicemen to just replace the entire board. (example as with the highlighted case) .

 

In part of the troubleshooting the issue , hope I was able to answer it technically as needed. 

 

Regards

Re: Lenovo Flex 2 Screen wont turn on

I have a similair problem. After I put my laptop, a Lenovo Ideapad Flex 15 that I bought back in 2014, in sleep mode last night, it stopped working. When I tried to turn it on this morning it flashed the power and battery LED, started up the fans and then did nothing. So I tried it again and again and again, but the same thing kept happening. Eventually it even got stuck in a loop, flashing the LEDs and staring up the fans without me pressing anything. I have already tried removing the battery. Pluging and unpluging it from the powercable. Everthing I tried failed, I searched every messageboard and forum for a solution, but the only real solution I could find was waiting and praying to the lenovo god that maybe, possibly, someday my laptop turns back on. I'm now done with Lenovo laptops, the not working touchscreen, not working side volume rocker and the not working of the laptop in general. I have a more than 5 year old laptop running windows XP, that works better than my current laptop. I really hope that somewhere, someone knows how to fix my laptop.
