Hp laptop 15-dao326tu 5 long blinks & 3 short.

1. My laptop won't boot up sometimes and shut down immediately after a few fan noise when I press the power botton.

2. Sometimes it boots up after I keep the laptop for a while and plug the charger in when I press the power botton.

Can you get into the BIOS/Setting screen? 5-3 flashing could be the system board. Lets narrow it down a little. Try taking out the battery, hard drive, DVD drive if there is one and Wi-Fi card. If two RAM modules take them out and try one at a time in each socket.

Plug in charger, without battery and see if you still get the flashing light codes. If not them reinstall the Wi-Fi, HD, etc. one at a time until the flashing code comes back. That is the defective component.

Let us know what happens?

I haven't tried some of your method, i.e., taking out wifi card and reinstalling them. Others I have tried. I am thinking of flashing bootloader, will this help if the problem is the system board?

Thanks for answering

@slemuk9 I think you mean the BIOS/UEFI but yes it is worth a try. They do get corrupted from time to time. Hard drive may have some weak sectors.

What is the exact model number of your laptop? And you would get a much better response if you asked a new question, with more details about what happened and what you tried, rather than tacking on a comment onto a much earlier question. Give it a try.

This happened to me after a windows update. Just before this started happening my computer was grinding to a halt. It's when the computer went to sleep it would do this. Also, just before this happened Windows "Hello" failed with my PIN with a strange message saying, "Something went wrong and your PIN isn't available"

This worked for me.:

1) Hard kill: When laptop is on (HP envy 360) is on, or when it is crashed with the blinking caps lock button (5 long 3 short) then just hold power button until it powers off suddenly. About 5-6 seconds.

2) Depress and HOLD the windows key and the letter B key at the same time.

3) While still holding the two keys down, Press and hold the Power on key for at least 3 seconds until it starts to boot up.

4) With luck, you will see it restoring the entire BIOS and then it will boot up with all your settings and files and windows in tact.

This could be your shot across the bough that the motherboard is about to go. Back up your stuff!

Hope it helps,

Replace the battery on the motherboard. Took me about an hour to fit a new CR2032 button cell. All is good now.
