  • How do I check the voltage of the old battery? Do I need to reconnect it to my laptop? Thanks so much for your help Jack! If you have Ko-fi or amazon wish list please let me know so I can thank you properly.
  • And it's working! Turns on, charges, stays on when charger is not connected, all looks great! I tried with the new charging port first and it didn't work. I switched to the original charging port and it worked right away. Seems like it was probably the battery all along! Thanks for your help! One more quick question, how…
  • Hello! New battery arrived and I installed it. Whilst installing it I noticed a slight difference between the battery numbers. The top battery is the new one and has the code A1CP5-57-80 whereas the old one has a code of A1CP5-57-81. Is that okay? I don't want to accidentally install the wrong type of battery and blow my…
  • I never had any problems with the screen/picture at all. It would just shut down after being on for a while (usually I would turn it off once it got to hot). This only happened when I played the Sims. Apart from that my laptop worked perfectly. I have ordered the new battery. I'll let you know how installing it goes. Silly…
  • I guess I'll try and replace the battery for now. If that doesn't work I suppose I'll have to send it off to get repaired and hope it costs less than a new laptop. How dangerous is battery replacement? I noticed the battery has tons of warning signs on it about not piercing it and being careful. How does this one look?…
  • Ah reversing the probes gives me -19.18.
  • This is what the screen looks like on the new charger. There is no plus or minus.
  • Thanks for the help again. I measured both my old and new chargers. Both came out around 19volts (new one was 19.11 and older one was 19.18). The polarity of the new one is +, not sure about the old one since the sticker came off.
  • Hello! I've got my multimeter. Reading through the instructions now and seems kinda complicated but I'm a faster learner. What on my laptop do I need to measure? The charging port?
  • Hello! So the charger arrived and... nothing. Plugged it into the laptop and turned the plug on, and nothing happens. I have tried with all three charging ports I have. I have tried multiple plug socks too. The charging light doesn't come on and the laptop won't turn on at all. I'm going to get a multimeter to test the…
  • Great! I've ordered it, should be here in 3 days! I'll post an update when I get it.
  • Thank you both for the help! Just double checking here, is this the right charger? https://www.coywood.co.uk/acer-swift-3-sf314-41-charger-76834-p.asp
  • I have a feeling it could possibly be the charger. Do you know where I can get a new one and what type I need? The sticker has come off the bulky bit.
  • I don't unfortunately. I could probably buy one. 
  • It isn't lighting up at all.
  • Update! Eventually, my laptop stopped turning on completely. I brought a new charging port (the one I linked from ebay), plugged it in same way as old one (it has a longer wire, but I can't find one with the same length of wire) and it didn't work. Old wire also doesn't work. I ordered a replacement wire in case that one…
  • Would this one work? https://www.ebay.co.uk/itm/325153891490 It has the same part number "450.0E70B.0001" as the original wire label. 
  • Thank you for your help. I am looking online now. From reading online I've seen people say you need to get the correct length of wire? Mine has a very short wire and I cannot find any of that length online. I am in the UK.
  • I contacted Acer but unfortunately, it is no longer under warranty and I cannot afford the £45 handling fee. I had a look at the charging port using a youtube tutorial. It seems easy enough to replace. Does anyone know which port I need exactly? The model number? There's a sticker on it but it's rubbed off, can only see…
  • Hi, I'm not the best techy person when it comes to hardware, would Acer be able to fix it for me? I sent them a repair request 3 days ago but haven't heard back yet.
