HP Laptop Won’t Turn On

Topic

New Reply

I’m trying to help a friend long-distance with her HP Envy 17 M7 17.3.

She replaced the battery with a new OEM battery. Sounded like a simple process once the bottom of the case was removed. A couple of screws and disconnecting the battery connection.

When she plugged it in the power light came on and over a few hours, the light changed from amber to white indicating a charge. However, it will not start when pressing the power button there is no reaction from the PC.  She has tried removing the battery and running off the power cord. She has also tried one solution of pressing and holding the power button with the battery removed and plugged in and nothing happens.

She had not been having any other issues with the PC and only replaced the battery because every now and then she was getting a message about a problem with the battery even though it continued to work normally. The old battery was slightly swollen.

Any other ideas or suggestions? Shouldn’t there be some response from the BIOS even if the hard drive failed?

some laptops need the battery in situ for the laptop to work due to the designed circuitry. Which leads to this

and it still wont work.

Not sure which model of HP Envy 17 M7 17.3 it is, can you give more details? Sometimes there are’quirky’ things to do with HP devices when changing a battery due to the circuitry involved.

I believe this is the model. M7u109dx. The rest of the info Intel i7-7500U | 16GB RAM | 1TB HDD | FHD (1920×1080) | EDGE-TO-EDGE GLASS TouchScreen | NVIDIA 940MX | Windows 10

hope your friend checked the old battery to see if she’s entitled to a free replacement

Thanks. When first installed the lights on the PC indicated that the battery was being charged and had been charged for several hours. Since the power light works I can only assume that the AC adapter is working.

I know she bought the battery so I assume it either didn’t qualify or she didn’t know about it.

Here is a YouTube video which shows what happens when following step 2.

This is gonna sound weird, but… have her power down, pull plug, pull batt, and try reseating her RAM.

When box seems completely dead like this (i.e., as in “maybe-the-power-supply-failed?” dead), you’d be surprised how often this trick works. Box tries to POST, fails on RAM, and just hangs…

Hope this helps.

Does it work with the old battery in place?

cheers, Paul

She did try it and it did not work.

Suggesting the laptop has died.
It may have been the new battery, installation or coincidence.

Good morning! Just came to the forums with this same question. I have an HP Envy 17-t –  17″ laptop with the same issue. It has been working fine last night, but this morning it appears to be completely dead and won’t turn on. It is now plugged in to charge – thinking that the battery went dead overnight – and the orange charging light is on, but nothing happens when I press the power button. I also don’t see any hard drive activity when I do press the power button, and no sounds or lights other than the charging light.

This laptop doesn’t have a removable battery – I think the case needs to be opened to access it, so I can’t try the suggestions above for battery removal.

Is there a way to jump start it with my Macrium rescue thumb drive – but I’m guessing it would need to power on to use that.

It is about 18 months old, and has run fine up until now.

Suggestions welcome! Thanks!

***ETA: OK – Sorry about that. I just went back to check and removed the USB for the mouse and it came right on – wasn’t even actually “off” – so I tried a different mouse and seems OK now. Sorry to have jumped the gun – hopefully this is OK now – but will keep an eye on this thread and post back if it happens again! Thanks for bearing with me!!

Just to update. She removed the HD and installed it in an external housing and she can access the files on it so we know it wasn’t a failure of the HD.

Here is the service manual for this laptop model:

http://h10032.www1.hp.com/ctg/Manual/c05282360.pdf

Did she make sure that the computer wasn’t in hibernate when she changed the battery?

In the manual, to get into BIOS it says to press the power button and then to quickly press the ESC key and then press the F10 key.

She did power it off prior to replacing the battery.

It appears that the M7-u109dx model does have a battery for the CMOS and RTC. See 2:24 in this YouTube video for the round CR-2032 battery which is located just left of center within the computer with the bottom cover removed.

https://www.youtube.com/watch?v=LgeHzELkp0w

It might be worth removing the CR-2032 battery, waiting 5 minutes and the reinserting the battery. Also check that the replacement lithium battery pack’s connector is fully seated. There are a few connectors underneath the replacement lithium battery pack. Those connectors should be checked as well.

After checking everything, simply attach the bottom cover without any screws, flip the laptop over and plug in power, and then try booting it.

If this doesn’t get the laptop to boot, check the broad ribbon connector cable which attaches to the top edge of the motherboard, the cable of which rests under the battery (seen at 2:58 in this video, and also shown in my attached photo):

https://www.youtube.com/watch?v=lqDIIZzH5gk&feature=emb_logo

This broad ribbon cable may have either been excessively creased by the original swollen battery or may have been pulled slightly loose by the bulging battery. She should check this flat cable’s connection to the motherboard. If the connection to the motherboard is good, then she should check to see if the flat portion of the cable is deeply creased by the bulging battery. If the latter, then this cable should be replaced.

I’d suggest unplug the battery connector and take a really close look (with a magnifier or loupe) at the connector, both on the cable and on the motherboard. Look for damage to a pin or to where the pins are soldered to the motherboard.

Appreciate the suggestions. I’ve been passing them along. I will post if something suggested fixes the problem.

She’s tried these suggestions this morning including replacing the CMOS battery with no luck. Thanks for the suggestions.

Have her unplug the AC adapter and remove the battery. Then she should press the power button for a full 60 seconds. Then reinstall the battery and plug in the AC adapter. Hopefully the laptop will power on when she presses the power button. If this doesn’t work, then it most likely is a dead motherboard.

I watched a few videos by repair technicians. They don’t seem to like HP laptops since the motherboards just die for no apparent reason. There are some dead motherboards (for parts only) for sale on ebay — no power, no video.

She has tried this more than once.
