Yoga won't boot. Red light comes on for 4 seconds no blink.

Q: Yoga won't boot. Red light comes on for 4 seconds no blink.

I had previously hooked this up to my big screen via the hdmi. The next morning I went to turn it on and got nothing. Holding the power button down with power plugged in, not plugged in any combination for 1 - 120 seconds produces the same exact result. The little light on the " i " lights up for exactly 4 seconds and then nothing. I have tried a different power cord and get the exact same result. I have tried using the emergency reset with a needle on the back of the device...same result. Any help would be great.

A: Yoga won't boot. Red light comes on for 4 seconds no blink.

Can you clarify when you say it "lights up for exactly 4 seconds", is it a solid light or a blinking light?

Hey there, everyone.I've got this 2 year old ThinkPad Yoga 12 that was working fine one day, and then won't boot at all the next. No screen activity, no backlight on keyboard, nothing except for a solid light on the "i" and then nothing. I've tried taking out both batteries, I've tried all kinds of combos of power button pushing, and I tried the reset switch. That caused the light to blink three times and now it's not doing anything. It does blink when I put the power cord in. Is my mobo borked, or is there something I haven't tried? Thank you!!!

My Yoga 3 was bought 3 months ago at a local retailer. It had been an open box model. A couple of nights ago while using it, my wife got a Blue Screen of some variety. Since then, the machine doesn't work at all. When I push the power button (or the reset button next to it), the KB backlight comes on and power light comes on for about a second and then they both shut off. This cycle is repeated indefinitely until I hold down the power button at which time everything goes off. That is the only response I get from the thing. This machine is only 3 months old but I cannot find any way to get in touch with Lenovo for any kind of support, so I thought I would try here first. Any help would be greatly appreciated. Thanks!

  Hello World.   I'm not able to power up a Yoga Ideapad 15.  When I press the power button, its led starts blinking, in synchonicity with the power light indicator, making a short blink every almost 5 seconds.   I've dissasemblied it. Fan cooler tries to start, but suddenly stops. This issue repeats every 5 seconds, same time as the laptop blinks.  I've tried common steps (like keeping the power button pressed with no battery and no charger). So, if anyone has a possible solution, I'll appreciate your help. Thanks a lot!

I ordered some new stuff, sound card, headset. So, i wanted to clean up my

computer before it got to the house. so i cleaned out everything, looking nice. i

put in the new Asus D2X and connect the Roccat Kave headset and the computer

only started for a split second. at this point only the fans and such connected

directly to my PSU would jitter / light up. So i took out my g

GFX card and...waaala. It worked, so i messed around playing with the cool Asus

software listening to 5.1 demos. Anyway I Talked to one of my friends who told me

to reconnect the video card into the primary slot instead. So i tried it and it did the

same thing again. Also i tried my backup video card with nothing doing. blinked

and stutterd for a millisecond and stopped, as it did before. Now, it is clear, i felt

relieved all it was, was the video card. so i can just use onboard until i find a good

deal, because my audio setup cost me 260$. Basically the question here is

why does it not work now as it did before i tried to setup the GFX card again. It

acts like the graphics card is still in there shorting it out or something.



please help, Thank you,

fter connecting the AC power supply to CPU and on pressing start button , CPU light does not blink spontaneously ,It took 3 to 5 minutes to start blinking and window start immediately as light start blinking on start button .Reliability report does not show any error.Pl suggest me some remedial action

A:CPU light does not blink spontaneously

Ehm, CPU is "central processing unit", a computer component. It does not have a light linked to its operation. If by CPU you mean the whole machine, call it "computer".

If that led is close to a symbol that resembles a lightbulb, then it's the power led, and tells if your computer is actually getting power or not. It should go on when you press the power switch and remain on until you shut down the computer.
If it is close to a cylinder symbol, it is the memory usage led, and tells if your computer is reading from its main internal memory device. It does blink randomly when in normal operation and if you don't experience other issues you can safely disregard it.

Other leds can indicate the wifi connection or whatever the maufacturer thought to place there, if it's not one of the above, try to describe it or find an image of it from google.

Please follow this tutorial to fill your system specs (step 7 to do it automatically), so we can know what is the thing you have in your hands. Without knowing more, help provided will be limited.

Hi,

I upgraded my HP Pavilion a1540n Desktop to Windows 7 a week ago. Ever since, my hard drive light constantly blinks. After looking at the disk activity in the Windows Resource Monitor and doing some research I am leaning towards the page file as the problem. I am not sure if that is in fact the problem as there seems to be quite a few processes creating high disk activity, including Firefox profile cache, $Logfile, and MpWppTracing.bin. I only have 1GB of RAM. Would I be better served to add RAM before doing anything else like using Cacheman?

After coming back, it now refuses to even POST. I tried every power cycle I could think of, in various combinations, and browsed several forums. In the end I found no functional solution. Current Status: System responds in no way other than the 'i' light (in the Thinkpad logo) blinking three times when the charger is connected, or the same when the reset button is pressed while the charger is still connected. Nothing else illicits any sort of beep, light, or otherwise. Any help is greatly appreciated. Thanks and regards.

I have Lenovo Yoga 910. It's a couple years old. Suddenly I experienced lagging with the keyboard. Every button must be pushed at least a couple of seconds to appear or response. Some buttons are worst than the others. I called Lenovo and was advised to try to do hard reset by pressing down the power button for 45 seconds followed by pressing the Nuvo button but that didn't work. The problem was still happening. It's not windows upgrade related because this issue was also happening in BIOS when clicking on the arrow buttons and pgup/down buttons. I also tested it in Safe mode and it's still lagging. I even tried restoring the original windows version that came from Lenovo and still didn't work.After researching on the net, some were saying to unplug the battery cable and plug back in to solve the issue. So i did that, I unplug the battery cable but NOW....I have a different problem, worst than before.Pressing the power button doesn't do anything, the laptop doesn't start up. When i plugged in the charger, orange light next to it is blinking. According to Lenovo manual that this means the battery is under 20% but I left it charged overnight and it's still the same (orange light blinking). Also pressing the power button still doesn't do anything. But i noticed if i keep on pressing the power button, it will blink white lights every 20 seconds or so.The battery was in good condition because I did Lenovo diagnostic before I unplug the battery cable so I don't think this is batter...

First of all thank you for trying to help!
My pc is rather new (3 months) and hasent been causing any problems untill now. In the last couple of days, i've noticed an odd increase in the hdd led activety. after reading up on the web, i figured this was probably due to vista background stuff. However, the problem got worse- to the point where the os couldent start after restarting. (it would start up fine from the cd drive). after a few restarts it managed to start up, and since then the pc is super slow, with hdd led always flashing.
this happend around the same time i downloaded and installed vista SP1.
I checked the sata connection to the hdd, but it didnt help.

i guess my question is this- is it hardware for sure, or could it be software? i can format if it's software, just wondering if i should. maybe the hdd is just dead...

Hello people...>!

I think I had been trying to fix this laptop for the last few months but was really stil not finding the root of the problem. Basically i had a problem with being able to charge my laptop when on or off. When it is on, the charge light will keep blinking but when it is off, it will flicker every 7 seconds. I had remove the battery and tried with the ac only and it does the same thing.

I also had replaced the dc jack and problem was not solved. My only guess is the ac adapter but I wonder if anyone have had the same issue like I am and hoping it was the ac adapter. I really do not want to buy an ac adapter and later on to find that it was not it but the motherboard so it will be a waste of money.'

Any suggestions or inputs will be appreciated.
 

A:Compaq R4000: charge light flicker every 7 seconds

You are definitely right...! Finally, it works again after I bought a new AC adapter. So the real culprit is the AC adapter. Anyone who has the same symptoms as I did, please make sure you suspect your ac adapter first before tearing apart your laptop. Good luck!!

Just AC cord in. Last night, as i was setting up a Wi-Fi router at home, i left it on for about 3-4 hours.When i finished, i powered it down normally. This morning, i took it out and set it on the dinnign table, and when i powered it up, the leds from the sound, wi-fi and mouse pad stay lit, the fan starts up, the leds from the caps-lock and num-lock blink once, but no bios or OS boot. I powered it down, removed AC cord and reset holding power button for 1 minute+ 3 times, then power cord in and powered it up and the same thing happened, but this time i got 2 blinks from the caps and num lock, then 5 second pause, and another 2 blinks: BIOS corrupted, right? Since i have customed my laptop with an HyperX Fury SSD drive 240Gb from Kingston, i don't have the partitions from HP Recovery or HP Tools, so i tryed to get the BIOS file from HP Support and created a BIOS recovery flashdrive. The BIOS file is not the latest BIOS update tool from HP, it's Winflash, so doesn't allow creating a recovery flash drive directly, so i extracted the contents and put it in a 4Gb flashdrive, formatted in FAT32, Renamed HP_TOOLS, and tryed the whole reset process, then hitting Win Logo + B keys in and pressing Power button for 1-2 seconds to recover BIOS. Worked once out of 7 tries!...

My daughter's laptop has died.  When you push the power button the power light on the side comes on and stays on and the hard drive light blinks momentarily then not at all.  There is a blink code on the Caps Lock key that appears to blink twice - one blink followed by a second about 1 to 2 seconds later, then a longer wait and the code repeats.  There is no LED on any other key.  I've tried the hard reset by pulling the battery and pushing the power key for a long time.  No change. I've looked up the blink code which says it's a corrupted BIOS and used the Windows key/B key combination before pushing the power button and nothing happens except the blink code continues. This is all that I can find to try with this laptop and the daughter needs it for her online college courses.  She bought it from Amazon and it is a refurbished unit.  Any suggestions? Thanks.
