Solved My laptop charger isn't working

Acer / 5820t series
November 9, 2013 at 13:27:14
Specs: Windows 7, Intel Core i5 CPU 2Ghz / 4GB
I have a Acer Aspire 5820T running on Windows 7 and I have my charger in it but it's not giving any power. If i fidget with it, after a while I get it in the 'sweet spot' (in works!), but now I can't even hit the sweet spot. Also, it's not one of those where it say 'Plugged in, Not charging'. Its' plugged in but not realizing it. What do I do?!

✔ Best Answer
Either the cord on the charger is broken or the power jack on the motherboard is breaking loose. You could try a new charger and see if that's the problem. If that doesn't fix it, you will have to take it in for repair.

Charger units seem to be somewhat less than robust a lot of the time...

Often they run close their stated output; often run "a little warm" - some might say warmer than is desirable... When chargers "warm" the risk of failure increases... - as it does for all electronics...

Also they have a history of cable failures; often/usually close the plug that goes into the laptop... "Some" replacement chargers are now being made a little larger (physically) but not noticeably so; but also may be using better components - or at least are designed to run a little less warm...; and thus hopefully have a slightly longer life - in that they won't die of internal component failure - too early...?

What you describe - fiddling around to find a connection that works as it were... suggests the cable has failed - and likely at the laptop end...

If you go to somewhere like Amazon and search for Acer 5820T mains adapter - or Acer 5820T charger - you will get more than a few sources...

I've had two Acer compatible chargers via Amazon - and been very happy with each. The first/original one that came with the laptop (8yrs ago...) failed I think internally - rather than at the plug end; the replacement - made by Liteon (as are most chargers supplied by Acer...?) - went somewhere in the cable (I think), The one I have now is branded as genuine Acer item; doesn't seem to run quite so warm though as the others did...

Incidentally the reason I suggest Amazon is because overall I've found the widest and best selection there; and Amazon do appear to support you should there be an issue with a vendor and duff/faulty charger still under guarantee... eBay does similarly I know, and I have been happy with eBay support etc. But have bought my replacement chargers various form Amazon...

Prices vary - cheapest isn't always the best... Check carerfully the models covered by a given charger; read any reviews/comments from those who have bought one. Also note the guarantee offered; some are a miserable 6 months, many 12 months, and a few 18 months...

I did a quick look-see and note they seem to go for around £12 - £25...

If you're in N. America check; and if elsewhere then whatever Amazon version is in your area...

Whichever charger you buy... ensure that the plug when in the laptop socket is "firm' snug fit; and doesn't wobble or seem to be a little loose... If it is loose etc.... send it back and ask for another... And also confirm with the vendor (seller) what size the plug is - if you have to return a charger with loose plug connection. They can be either 1.5 or 1.7mm pin diameter, and the outer/overall diameter is usually 5mm - depending on the make and model of the laptop...

But if a given charger is described as for your model Acer... it ought to be OK...

Hi Catrio,

here in the UK, the last Laptop psu I purchased from Ebay UK, a few months back, cost £5.29 in total including postage. It was not the cheapest.

Often forgotten is the www is truly ww, and with e-commerce it can be cheaper to purchase from one country (from ebay/amazon/whoever) and send to another country, even when including postage. for example:-

a) laptop battery from UK to Italy was 1/3 of Italy cost
(actually came from Chinese company with UK warehouse)

b) computer game from Greece to Italy was 2/3 of UK cost

Good Luck - Keep us posted

Whenever something changes when wiggled the fault is usually very close to that place. As often as not a poor connection - could be cable or something needs re-soldering or tightening.

Always pop back and let us know the outcome - thanks

Hi Derek,

my experience with these, is generally the psu dc cable fails where it enters the dc power jackplug. This tends to be caused by the plug being straight, which when in use the cable needs be bent, and this is the stress point where bending occurs.

If only more jackplugs where bent, or inexpensive 90 degree adaptors where available!

When repairing the jackplugs, as they are generally moulded a replacement is needed, otherwise one has to bodge, and then the repair is unsightly.

Finding a replacement plug can be difficult or impossible as there are many different sizes and shapes (e.g. Dell Hexagonal). If lucky and a plug can be found, it can cost £1.50 - £2. Thus it is easier to purchase a complete psu, especially if an oem one costs around £5.

Regards - Mike

The replacement Acer 1692 chargers I have had (all three) had/have a right-angled plug connector. (I think the original supplied with the laptop when new was a non right-angled version; but since then all chargers been shipped with the right-angled version.) One definitely (not definately as one sumtimes sees on sum forums…) failed at the at end of the cable; just before the insertion point into the plug itself. There other two failed within the charger electronics…

My brother has had several charger units for laptops various over the last 8yrs… (His family all have Acer laptops - and very happy with them overall…) All of the chargers suffered cable failure at the insertion point into the right angled plug. He and his family do seem to plug/unplug somewhat more often that I do… which may account for the cable failures overall? Which having said… I am aware that the problem is not limited to Acer chargers. I have seen Toshiba, HP and Dell chargers available too, at a local parts store;and the shop owner confirmed he does sell more than a few
(big/main name branded as well as generic - Liteon etc.)…

The cable quality could be better; but size may be an issue here, and a consequence too of miniaturisation of kit?

If one was to loop the cable back over itself and then tie it (twist tie or even a little tape) against the strain-relief (the thick sleeve/jacket around the cable at the plug entrance) that may provide some protection at least - and help reduce stress on the more "delicate" cable innards? i.e. tie the cable that is before the usual in-line "junction box" against the plug strain-relief. Would also give a better purchase/grip area too if/when removing/inserting the plug….?

Strangely… Apple moved from straight through connectors on their laptops to the right-angled version; but have retained the straight through style for iPads etc…? When I asked at Apple why the change I was advised it was to reduce cable failures at the plug end… Apple connectors are magnetic too - for laptops at least…; which means they will disconnect easily if one was to trip over he cable - thus avoiding dragging the laptop to the floor and wrecking it or the cable...

Agreed "stress point where bending occurs" makes very good sense. Similarly, laptop screen cables often give trouble around where the screen hinges.

Always pop back and let us know the outcome - thanks
