Laptop Won’t Turn On Unless holding down some keys 4

I must say that this is bar far one of the strangest issues I have ever seen on a Laptop. It get stranger yet as the solution is so far removed from the issue that you may never guess it. This issue is the Laptop Won’t Turn On Unless holding down some keys.

Now the keys that you have to hold on to for the Laptop to boot up may vary with this issue. In my case I had to simply press and hold any key and the Laptop would boot up fully. If not it would not boot up in most cases and simply reboot within a few seconds or go black and be in a loop. At best you may get it to boot up on a few occasions but it would simply reboot again.

As for the keys to hold in some cases you may have to hold down shift, control or so on. But you get the idea. The problem is a real annoying seeing that you cant tell when your Laptop will reboot and holding the keys in some cases brings you to login and you can use the Laptop but you don’t know when it will simply reboot at random.

What device did this Happen with?

Do note this will and can happen with any know Laptop that’s on the market. In my case it was a Acer in this case. Expect this can happen to Toshiba, Dell, Samsung,Asus and all other Laptop brands.

Whats caused the Issue?

The issue is caused by a faulty Keyboard. A damaged keyboard can be caused by many things such as damage due to shock, excessively pressing keys as kids will do sometimes, dropping your Laptop, spilling stuff on it or the keyboard simply died naturally or prematurely.

How to Fix this Issue?

In this case the problem was caused by a Faulty Keyboard. Chances are that if you ever dropped your Laptop the issue might not show up right away but it can lead to this issue.

The problem is though it can seem as if the issue is caused by something else but in order to fix this problem you will need to replace the defective keyboard with a new matching one.

You will need to find a replacement keyboard that matches your model and then replace it and the issue will be fixed. Do note it will take some skill to disassemble your Laptop and replace the Keyboard if you are not up to the task take it in to a professional before ordering the keyboard.

Also make sure the Keyboard matches your Laptop before ordering as this is very important.

What Can I do while I wait for the New Keyboard to Arrive?

Glad you asked in most cases your keyboard will either work partially for a while and then will most likely go dead and leave you without a means of inputting text. In such cases:

Use onscreen Keyboard: The on Screen keyboard can be found in Windows 10 at start (Windows logo bottom left of the screen), Settings (Gear icon), Ease of Access, Scroll down in the left panel to Keyboard, where you see: Use the on-screen Keyboard turn that option to on.


Hold down Windows key + CTRL + O if your keys partially still works.

You can now input text with the on-screen keyboard as you did with the physical one using your mouse.

Use a External Keyboard: Go ahead and get or buy a USB keyboard or a wireless one and connect it to a empty USB port. You will be able to type using the external Keyboard easily until the replacement arrives for the Laptop keyboard.

How to Replace your Laptop Keyboard?

Most keybaords are replaced in the same way and its a relatively easy or moderately easy task. The problem is that there is one keyboard that pops right out when being replaced and another that’s deep within the Laptop and behind a cutout through which the keys popup through.

I will show you how to change both starting with the simple and then the more complex one in two separate videos.

Simple Keyboard replacement:

Laptops with simple keyboards are designed to be changed conveniently and best part you don’t need to take the entire Laptop apart to do it.Written guide here.

Laptop with Complex Embedded Keyboards:

Laptops with Complex as I like to call them Embedded keyboard require you to disassemble the entire Laptop to change a simple Keyboard. You can read the written guide for these Laptops here.

    Great job, Ricardo. You nicely explained the cause and solution of the laptop won’t turning on. I hope people will able to deal with this problem after reading your post. I liked your HP 15 Series laptop damaged keyboard replacement video guide. Thanks for including.

    Wow, I have been a tech for over 20 years and this one had me stumped. HP Z book G15 was knocked out of my car using HPTuner (OBD2 interface) by my dog. It didnt hit the ground that hard but it would get to the HP logo and then / by 0 loop, 3 beeps and 1 white flash on the caps lock key. There is no HP error code as far as I can tell. I did get it to boot normally and work once. I thought it was okay until the next time I tried to restart, but it wouldn’t do it again. I was able to get to HP diagnostics, mem and hdd checked out fine.

    I thought it might be something with the video(it has 2 video cards) so I thought it might be the NVIDIA card become unseated, or 2 of the 4 ram slots could have someone unseated. Tore it apart, cleaned and reheated video card and ram, same deal. I started holding down keys as it was in infinite loop and holding the control key it would start boot and go black if I let go of the key, same with a few other keys, but the ‘windows key’ would get me to the desktop, but as soon as I released it, blank screen.

    That led me here, and the keyboard issue makes sense, but it turns out it was some issue with the NVIDIA card. Switching back to the sucky Intel graphics let it boot normally. It still could be a DMA conflict issue with the keyboard. I will see one day if I have nothing better to do. Keyboard is working fine for now .You have to really pull harder than I would like to get the keyboard out , and there looks like a high spot on it. All the keys work.

    It took forever to find the drivers for the NVIDIA card, and it didn’t seem to make any difference, although you have more control options.

    I hate Hewlett-Packard desktops, non laser jet printers , but i have got to say they do make good and durable laptops. I like the Zbook for the extra ram (32 gig’s max) slots and dual video. I did have to replace the MOBO a couple of years ago because some gooey liquid somehow seeped upwards, and killed the power controller. I still dont understand how that happened. But it takes a lot of abuse. I have an old Elitebook 15 that I use as a backup and other than the backlight being broken, it works fine with a monitor attached
