I have an old laptop which I no longer have the charger for. I ordered a new charger for the same laptop series, but the plug is too large, and it is unlikely that I will find the same adapter (Acer is difficult with their proprietary plugs).
I have an idea to connect the power supply directly to the laptop. 15.2V is the battery voltage. The charger provides an output of 19V at 3.42A.
Is it possible to do something like this?
Laptop model: Acer Aspire V3-371-558L
Title is slightly inaccurate. It's more whether it is possible to switch out the power supply of the laptop from a battery to a power supply, akin to a desktop, which are non-portable but function off wall power. – Anton8000 – 2016-06-09T20:33:09.757
Title has been changed, this one should be more accurate. – Anton8000 – 2016-06-09T20:43:23.840
That is better, but it is still unclear. You say "connect the power supply directly to the laptop", then mention battery voltage and charger voltage. You are not clear on how you intend to connect the power supply nor what its power ratings are. – CharlieRB – 2016-06-09T20:47:15.553
The exact model would also help to clarify how it deals with the battery being absent and how the built-in power supply or distribution is handled to see if it would tolerate your transformer. An even more important question is whether that new power supply is switching, which is the main characteristic of computer power supplies and increases their price threefold. If it's not a switching PS, you should just forget about the whole question as you'll ruin your computer with it. – Julie Pelletier – 2016-06-09T20:58:16.497
