My old (kinda old - 2018) Acer Aspire E5 started acting weird by not powering on sometimes. Sometimes it will boot, sometimes it will not. Just blank screen and power LED for 3sec and then shutdown. I did everything I could to troubleshoot this, changed RAM, tried different power adapters, removed every possible component from the motherboard, and so on. Basically did everything that every tutorial on the internet tells you to do in this situation... I gave up since I couldn't resolve this issue myself and just let the guys at a local repair shop find out what's the cause of this issue.

My initial guess was that the laptop is not POSTing and something prevents it from properly booting up, either a short circuit or faulty component, but IDK because it was so random that sometimes it boots up and sometimes it doesn't.

Two days after the guy at the repair shop told me that it's the motherboard issue, something to do with auto-cutoff, which needs further investigation and the price is going to be RM390 (+ RM30 for inspection), with two weeks repair time. I'm still to decide whether to take the laptop from them or keep it for repair. I'm kinda skeptical since I've never had anything repaired by someone else and I want to be sure that I'm not being scammed. Is this a reasonable price for this kind of repair? I'll be glad to see what you guys think about it, maybe there is a reason for this whole thing that I don't know or it is easily repairable...

have u tried with a different ram module? but this looks like a mobo issue.

Nevertheless try this

1. Pull the battery

2. Unplug the power

3. Remove the memory, hard drive and any cards like WIFI

4. Plug the power only back in

i think it's a rip off....did he tell you what wrong first? IC burnt? What? If he can't tell, then he can't fix and probably just selling you another old spare mobo from somewhere by doing a total replacement. He will check and tell u what's the problem and cost first.

There is a guy in Garage Sales...he fixed my mobo before....an middle age Malay unker. Can't remember his Nick though...you go search.

Yes, as I said, tried everything I could, even bare motherboard with no RAM, no HDD, no cards, no battery, and fan - power cable only, still shuts down in 3 sec

best to bring to several shops to check what is the issue. But i suspect it's a mobo .

No... he just said that it's a motherboard issue with auto-cutoff, and he will TRY to repair it... He didn't say the exact issue. As for the spare mobo, the price for this laptop is around RM1000+ so I don't think he'll try to replace it...

Common issues if not due to water damage is faulty EC chip or chipset issue. You can also open up your motherboard and see if got any component smelling funky

For aspire e5 with i5 4210u where chipset and cpu are on the same package, might need to teplace cpu if chipset issue.

My Dell Latitude E6540 refused to power on via AC adaptor or charge the battery. It can power on from battery thought.

Replaced with a new AC adaptor but in the end, it is the 3 MOSFETs on the motherboard kaput. Replacement took about a week and cost about 300 bucks.

IMO, it is quite expensive to repair locally as u can buy a refurbished motherboard from AliExpress for the same price and wait about 2 months.

If the board costs you almost 500, not worth for me

Buang je, i wont consider to repair laptop mobo. Would be better if you buy new.

Ehh.... why repair until RM390? You bring back to Acer service center ka? Go to IMBI and the repairs generally cost under RM200.

Usually, when it comes to fixing a computer, it's a hassle to narrow down the exact problem. So sometimes computer shops just try to troubleshoot a specific area i.e. motherboard and conclude that it's easier to just replace the entire thing rather than fixing the actual issue. Sure it's costlier, but that is for the customer to worry. And you can't really blame them. If the problem only requires a simple replacement part which cost RM5, then there is no guarantee if the repair won't cause other issues, apart from the minuscule profit made from the repair versus the time consumed (small components are much harder to replace than an entire motherboard).

As for the price quoted, it could be the shop is thinking to get a refurbished motherboard and replace it to yours.

You looked at the wrong place to fix the laptop. If you have an Acer machine, you should have send it back to Highpoint ( Acer Service Center in Glenmarie) . When you say, the 2 weeks repair time, I already suspect that the repair guy just send it to Highpoint himself and charge you for commission. When I had an Acer laptop long time ago, I sent to Vital ( very big repair shop in Lowyat and has many outlets in KL, in the end come back unable to fix, then missing screws) . Only Highpoint manage to fix it for me, a motherboard replacement costed me 400+ , my laptop was RM4k+ back then.

Mobo died good luck get repaired. I fried my msi laptop (water dmg), and msi won't honor warranty and gave me repair quote price of new same laptop minus 1k. That is to say it will cost me 4.8k


Edit: check my old email frm msi.

Hi, i know the cause of your laptop sometime can and sometime not power up problem. and i can fix it.

my name is Ang. 0122980599.

I think your laptop battery is built in right?

once you plugged in your acer laptop, 19V DC from adaptor will enter your motherboard and stop at first N-ch power mosfet. The mosfet is like a valve in a water pipe, valve open water can pass, valve close water can not pass, valve open a bit water pass abit. this Mosfet open/close is control by charger chip model bq24780s.

Acer design the board that initially it use the battery power (11.1v) to trigger the mosfet, so if your battery power is low than it will unable to trigger the mosfet.

your case is sometime on and sometime can not on mean your battery now can hold power just at bottom line of minimum power to trigger mosfet. after some time your battery become weaker and you will totally can not power up.

so replace the battery can solve your problem or modify the circuit a bit so that the mosfet use adaptor power to trigger mosfet instead of battery.

If you cancel repair you still need to pay for send in checking fees.

To me the price for a motherboard repair RM390 and a RM30 consider cheap price.

Don't be a cheapskate if you want professional help.

During learning stage they did paid a hefty price for experience. You think about it what they paid to be here today.
