Microsoft Surface Pro 4: Surface Pro 4 won't turn on at all after battery replacement

Fri, 02 Aug 2024 18:48:33 -0700

Hey! So I followed the guide here on iFixit to replace my battery. Unfortunately now my Surface Pro 4 won’t turn on at all (unplugged or plugged in). Nothing happens, not even the fan goes on.

I can’t really figure out what the problem might be. Maybe someone can give me a clue where to look next or what it might be?

A few more notes:

When I tore off the screen I broke one of the three antennas at the top, but I would guess this wouldn’t cause this problem.
When I first tried to turn it on, I forgot to connect the fan back to the mainboard. I fixed that very shortly after.
After it didn’t work the first time, I removed the battery again and put it back in, but that didn’t help either.

I hope that is enough information!

Microsoft Surface Pro 4: After replacing sr pro 4 LCD,won't turn on battery mode unless plug it

Sat, 02 Aug 2025 11:19:12 -0700

After replacing the surface pro 4 LCD, it won't turn on the battery mode unless i plug it with the charger

After i had replaced a surface pro 4 LCD, won't turn on battery mode unless plug it.

Before taking off the broken screen the pro was working good just the screen was broken, so i turned it off then started working on it. after taking off the old broken screen. i tried to connect the new LCD on to test it but no response at all.

it does only work when i plug it in the charger and it does show me that the battery is 100% full on the screen?

also i did put a piece of paper between the connects part for the battery and the motherboard. it does show me an X on the battery icon on the screen when i turn it on

but i couldn't resolve the problem for 1 week now and i have been searching online but no one has had these issues before.

so how can ifixit ??

Microsoft Surface Pro 4: Can I replace the hinge or kickstand of my Surface Pro 4

Sat, 11 May 2024 08:08:22 -0700

I accidentally stepped on my Surface Pro 4, and one of the hinges on the kickstand broke. Rather than replacing the entire device (I do have a warranty) I would rather try to fix it myself. The left friction hinge still works fine, but is not strong enough to hold the device alone. The kickstand itself is not cracked and would not need any replacement, only the right hinge is damaged.

Thanks.

Microsoft Surface Pro 4: Can Pro4's Samsung screen being replaced by LG's?

Mon, 28 Oct 2024 20:06:00 -0700

Unfortunately, I also suffered LCD screen failure of Surface Pro4 like the most of people. I don’t know how to called this issue but I believe you know.

Now I’ve purchased a brand new LCD pannel from Chinese Taobao to replace its original pannel Samsung LTY123YL01-005 (AIDA64 shows -001 though). I’ve learned from forums and websites that Samsung’s screen for Pro4 has flaws and Microsoft switch it to Pro5’s LG LP123WQ1 at the last batch. So I also purchased LG’s.

The seller told me that connector cable also needs to be replaced because Samsung’s is not compatible. After a few days I received my new scrren and connector. But after installation I can see nothing showing on the new screen, it was totally black including the backlight.

I’m confused. Is that old Surface Pro4 model incompatible with new LG screen? The new connector can connect scrren to mainboard correctly and OS boots normally but I can’t get any image.

Another thing is I discovered this new connector’s solder joint having some problems. AIDA64 cannot find new pannel’s name(viewed from Microsoft RD) and I doubt that the seller sending me a bad connector.

Now I’ve bought a new connector from another seller and it’s on the way. But I still holding the question. Can Surface Pro4’s Samsung screen being replaced by LG’s directly? Did anybody also completed the same replacement?

Microsoft Surface Pro 4: Is there anywere I can get a glass screen replacment

Wed, 22 Mar 2017 05:44:13 -0700

I have just dropped my surface pro 4 today ad its go a minor/bad crack in the screen, there is nothing else wrong with the machine so the LCD display doesn't need replacing. I've googled it but no suitable places have come up and not much information is being given. if anyone has any suitable places then I would love to give them a go.

I live in Hertfordshire so anywhere around there would be great

Microsoft Surface Pro 4: Surface not turning on - burned diodes

Tue, 10 Aug 2021 12:03:11 -0700

Hi dear ifixit users!

I have an Problem with my Surface. It's not turning on anymore after someone changed the screen on it. I quickly dissasembled it and spotted these 3 diodes that looked burned (I circled them in for you too):

Now my questions is can anyone tell me which diodes these are? I want to try to replace these 3 to see if it works again. It's currently not even turning on even with the charger plugged in. The Charger lights up tho. Do you guys think this might be the solution that fixes it? Or might be there something that is also broken that doesnt let the surface start?

Thanks in advance

Microsoft Surface Pro 4: Blurry texts and screen flickers

Wed, 08 Jun 2022 06:54:07 -0700

Texts are blurry, screen flickers and video/image moves under frozen one.

How to correct it ?

Image and text on the screen use to tremble, up and down, from time to time. When this happens image and text become blurry.

When video is playing,sometimes, one frame freezes, while in the background the video is still playing.

Is it a software related problem or a hardware malfunction ?

(once I hooked the Surface to a monitor, the video played fine,while the problem persisted on the Surface screen)

Microsoft Surface Pro 4: Battery Not Present After Battery Replacement

Wed, 01 Dec 2021 08:35:39 -0700

I just replaced the battery in my SP4 using ifixit’s excellent guide. I have not adhered the screen to the base yet because I wanted to test first. Attached AC power and turned it on. Everything works except it is reporting “Battery not present” and dies as soon as I disconnect AC. Device manager also has nothing under Batteries. Any ideas? Thanks!

Microsoft Surface Pro 4: No power when disconnected from AC Adapter

Tue, 12 Mar 2024 15:34:49 -0700

So the problem I'm having with my surface pro 4 is that it dies when not connected to the AC adapter. Instantly as though it has no battery power. Now I know, most of the time this would be the battery. So here comes the unusual part that has me wondering if it really is or not. Battery Report shows that the battery is there, fully charged and functional. And the battery meter also shows fully charged and plugged in. I've Updated drivers, windows and have even reinstalled windows hoping it was a software problem.

Any other suggestions or can we conclude it is just a faulty battery? Thanks in advance.

Hi everyone,

I am in the process of doing my first screen replacement on a Surface Pro 4

I've got the screen off and disconnected all the cables without an issue following the guide here but I accidentally snapped one of the WiFi antennas during the screen removal.

The only website I can find for the part is :-

http://www.powerbookmedic.com/Microsoft-...

However they are out of stock

Anybody know another place I can get one? Tried searching for the part number (X939878) online but that's the only useful website that comes up.

Help!

Microsoft Surface Pro 4: Is there any possibility that a Surface 4 has Surface 5 LCD?

Thu, 06 Apr 2023 19:17:21 -0700

I have Surface Pro 4 (This is the gift I have received) I dropped it and broke the LCD.

I bought an LCD, for Surface Pro 4, to repair it, from eBay. I removed the broken LCD, but the new one did not match the original cable.

I searched for letters written on genuine LCD, the letters is LP123WQ1. When I searched I got it was for Surface Pro 5, 1796.

I don’t understand, because mine is written 1724, behind the back.

What should I do?

Why is there another version of LCD on my Surface Pro 4?

Can I fix it with LCD, bought eBay?
