My Laptop screen is blank but the laptop is running

HP Recommended
HP ENVY 17-j101tx Leap Motion TS SE Notebook PC
Microsoft Windows 10 (64-bit)

I recently unplugged the CMOS battery from my hp envy 17-j101tx touch screen laptop (because it was taking a lot of time to boot windows 10) and plugged it in then I booted the laptop. I thought this would help but the laptop boots but the display is totally dead (as if its not even on). I tried some solutions offered by hp but it was to no avail. I tried reseating the ram, resetting the bios, plugging it to an external monitor, updating the bios firmware from usb but none of these works for me..Now when I start the laptop, the caps lock and hard disk LEDs blinks once every 5 seconds and after 35 - 40 seconds, the blinking stops and still no display. What should I do next. Please help.

Removing the CMOS battery in a laptop is a TOTAL waste of time -- because all the battery does is provide power to retain the BIOS settings when the laptop is powered down so they don't revert to the defaults.  You accomplished nothing by this and possibly damaged the laptop in the process.


Sorry for the bad news, but when a laptop does not even power on, you have few if any options for getting it working again on your own.

To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself. You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

But if it is NOT possible to run diagnostics, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it. And the problem with that is, while HP does do repair work of some sorts on PCs still under warranty, they generally do NOT do repair work on PCs out of warranty because they are not a general purpose repair facility. You would have to contact them in advance to see (1) if they are willing to work on it, and (2) if they will provide you any kind of repair cost estimate.

Since you live outside the U.S., here is a link to HP Service Centers, by Country/Region:

If that link does not get you a useful page, then use the main HP link:

If you can't get assistance from HP, then you will have to seek out a local laptop service facility to have them examine it for you.

Good Luck
