Acer Aspire 7540 Laptop Powering On. Screen Not Coming On.

[@John_B_Gage]

UPDATE: I tried changing the CMOS battery and the screen still doesn't come on. Seems more serious so the laptop has now been thrown away.

[@SatimoDZN]

im on the same stuff right now but there's hope if you get the body of the display off you can see a cable going from the battery to the display, the cable is the issue all you need is to repair it

[@Mr1991STE]

Flu issue needs reflow

[@lumirindrak2000]

Thanks guys, i replaced the BIOS battery and it works!

[@ryanlockhart2255]

Its the cmos battery. Its a cr2032. Took me 10-15 min to get the laptop apart to get to it. I have this same model. Take all the screws out of the panel on the back to access the harddrive and ram area. Remove the hardrive, remove the battery and the 3 screws under it. Remove all the screws on back of laptop. Take the part above the keyboard off with a flat head pocket screw driver and then remove the keyboard. Take out the 4-5 screws under and around the keyboard and lift the bottom panel where the mouse bar is and the battery is underneath it. I didnt even take the whole panel off just lifted in that area and pulled the cmos battery out. Replaced it and it works fine.

It's that lil battery thingy

[@nicolasb.2223]

Thanks Ryan, followed your clear instructions works !

[@deborahgallo6730]

thank you so much. when I turned mine on the black screen was gone and a faint white screen was there which usually happens just before turning itself on......however this time nothing happened the acer symbol never came on...anyway I did what you said about holding all the keyes down...the screen went black...and when I turned it on again it had fixed the problem...the system is running as it should all because of your video...thanks so much from Aussie land..

[@mjhoogendoorn6201]

Ive had the same issue until today, i replaced the CMOS battery and it worked

[@jamesfedevich9458]

Changed CMOS battery CR2023 and she booted up fine. Undo about 8 screws from back gently pry open from front below touch pad one inch to access battery. Change then restart. Good luck

[@John_B_Gage]

I tried changing the battery and it still didn't work so I threw it away.

[@MikeVarga]

Thanks for your post.. The CTRL-ESC-Power button helped.. After changing the HDD to an SSD I couldn't get any video.. After doing what you prescribed, it powered up correctly..

[@nlartsdesign]

Well mine worked as you said Mike CTRL+ESC+POWER and then removing finger from the power button only while still holding down CTRL +ESC and boom! Almost 3 hrs trying to figure out what was wrong with my laptop. Thank God for KZbin and thank God for people in the comment section. Also, I want to point out my issue just in case someone out there has it too: I was playing a videogame (Sims 3 Disc). Apparently it overheated and it shut off completely. My laptop was on top of two speakers leaving an area for wind from a fan to pass by (I had the fan pointing at the back of the laptop entirely while playing). This is not new for me because this laptop has done it so many times. The difference was that it couldn't boot up by itself this time around. This is Acer Aspire 5538 Win7 AMD Athlon 64x2 processor L310(1.20Ghz)4gb RAM 320HDD.

[@musdg864]

Omg you are the best-Firstable i clean my ram and then i turn on with ctrl+esc+power on and boom i have screen thank you bro

[@strudders2112]

Yep this, thanks dude...

[@svenadrian8885]

Can u please tell me how to clean the ram

[@theunknownandunsolved6963]

Yo john, if you didn't fix you're comp yet, and didn't put in a new CMOS battery, do it. I just dropped 8 hrs into fixing my mothers aspire 7550, i had the computer apart twice checked every connection over and over...yeah i changed the CMOS battery and the screen turned on, i still dont believe that the computer don't even tell you to replace the battery, just gives a black screen. Crazy as hell man.

[@supermanel1941a]

it worked for me. Thanks. - Damn this ACER piece of trash. Even on warranty ACER Service Center does not take any fixing.

[@sebastianf7003]

Had the same problem.I just took that acer apart. Screen to the body checked all cables and it's working again.

[@ecv4647]

I had same issue on an Acer Aspire V17 Nitro 2015 model. I disconnected the internal battery pack for several minutes and reconnected again, this fixed the problem. Also my battery is bad have to replace but computer works plugged in.

[@thundercracker3547]

Waste of time, ty

[@masamus6570]

Thank you control escape power worked.

[@flor1008]

the Problem is by the brocken chip called "northbridge" the only way to repair is remove the old Chip and place a New one Inside... But is to Hard without profesional equipment. I have the Same problem

[@toe_tag_9766]

I don't think acer uses northbridge chips. Mostly amd and ati.

[@metalkokorea]

push the start button for 1 min. without the battery,

[@LUNARIAproject]

Thanks so much for the tip on ctrl + esc + power on! I had the same problem, I tried FN key + esc + power on and started it up, but nothing happened more than the regular black screen, but then while it was on I instead held down the ctrl + esc + power on and it restarted and there was the screen! Incredible!! :)

[@musdg864]

Omg you are the best-Firstable i clean my ram and then i turn on with ctrl+esc+power on and boom i have screen thank you bro

[@JoachimLevel]

wow, it actually worked, thank you! well not really - went black a few moments later

[@A7M3D-AS7]

Please I can't understand can you tell me the tips again pleaseeeee

[@MrSegAsh]

Looks like it needs the Onboard Graphics chip reballing John. the solder has become brittle or hairline cracks. Common with these boards.

[@jennymahon54]

Silly question but going to ask anyway, do you think the screen might be broken?As you posted this video nearly a month ago, did you cure the problem?

[@John_B_Gage]

+Jenny Mahon It may be the motherboard or the video card. I have plugged a external screen into the laptop using VGA and HDMI and they are not coming on too. I have not fixed it.

[@jennymahon54]

Ok Thanks for reply. Jen x

[@neilgriffiths4757]

Hi John, I've had this problem from new 7 years ago and should have taken it back, but I found that if you close the screen (shut screen down to keyboard) and then wait for the left blue light next to the clickbar to go to yellow (takes a few seconds) and then open it up and press the power button it will start normally. It usually happens to mine if I don't use it for more than 12 hours. Good luck, hope it works for you.

[@SandervdEnde]

[@patsabpat]

^^^ THIS for the win. My 7540G was exactly the same. Battery change fixed it - just a shame it's in such a hard place to get to (almost a complete tear down).

[@sasindu2164]

Thank you so much

[@John_B_Gage]

I tried changing the CMOS Battery and the screen still doesn't come on.

[@theunknownandunsolved6963]

O that sux man, I've worked on computers for years and fixed many many of them, i never seen a computer that made the screen black wothout a CMOS batt. It blew my mind that was the issue. I was hoping maybe you didn't try that yet. Have you opened it up and reseat the screen connections? The main connection isnt bad to get to, the one one the back of the lcd is a bit harder. But Acer is known to have an issue with those cables.

[@John_B_Gage]

To be honest Getting to the battery wasn't easy. I did damage the keyboard slightly. Acer made sure that it wasn't easy to replace so, it's gonna get thrown away.

[@theunknownandunsolved6963]

@@John_B_Gage send it to me! Lol

[@John_B_Gage]

It would cost more to send than it's worth. lol. I just salvage whats good then throw the rest, ie the RAM and the HDD. Laptops are a pain when they go wrong. I always stick to owning a PC. At least you can replace the parts easy.

[@theunknownandunsolved6963]

[@fcwennekers7588]

Did it work?

[@John_B_Gage]

I forgot all about it. Sorry.

[@fcwennekers7588]

John Gage Thanks anyway, I got the exact same issue. A friend gave it to me and asked if I could fix it and I can't find the problem.

[@John_B_Gage]

I will try the battery just to see if it could be that. That would be a cheap fix.

[@wis2142]

Hi John, try William Yu's excellent "How to fix or troubleshoot a blank or black screen not powering up issues laptop"; if your friend has not replaced the device. Very methodical & fairly easy to follow. Author also took the time to explain the rationale for each step. KZbin's spam filter has prevented me from posting URL's in the past; hence the author & title given instead. After spending nearly a day attempting to fix my Acer 710 Chromebook, found the above cited video, reseated the ram stick & (Allah kareem!), got the screen back.

[@TheAbbaesque]

[@1gamewin]

Working on this issue for a client, same laptop, and in my case, it was the CMOS battery. I have never seen a computer not boot because of a dead CMOS battery, but I guess this one is an exception. To anyone disassembling, you can probably google guides online, but to do a quick instruction to those who are pretty familiar with laptop disassembly, it’s like most laptops that you unscrew from the back, pop out the keyboard, unscrew underneath that, then pop the top off, but with a twist I haven’t seen before: the clips that hold in the keyboard don’t move. You have to take the small panel at the top off that has the power and other buttons, then you can take out the keyboard, unscrew everything, INCLUDING the hinges, unplug and deroute the LCD cable and radio antennas, take the screen off, then you can finally take off the rest of the top case.
